Hi John:

Sounds like the fiber optic solution a la K5NA will do the job, but
there is another way to get an isolated RS232 link.

You can use optoisolators. Of course, I am sure you already know how to
do that, but you might not  know that there are integrated solutions
available. When I was at Maxim Integrated Products, Sunnyvale, CA in the
early '90's, we were developing a hybrid RS232 transceiver containing an
opto interface. intended for UL approval. Functionally, it was identical
to standard RS232 transceivers, but with a 1500 Volt isolation barrier.
And it utilized Maxim's single-5V supply technology. It was intended to
solve the problem of dissimilar AC grounds, encountered when connecting
computer systems running off different electrical panels. This is of
course a common situation in industrial/commercial applications. I
believe the unit is in production, but I forget the part #.

I don't know how it stacks up for RF pickup--Applications Engineering
can  tell you--but it solves the floating AC ground problem, bigtime.
You might want to check it out. The engineer most intimately associated
with its development was Bob, AA6BT. Maxim's phone is (408) 737-7600.

(Disclaimer--I no longer have a direct connection with Maxim. I do own
some stock---luckily, cuz the company is a Rocket.)

I need to know if E-mailing these pieces is possible?   They must also be

as my checking will not work.

I need several knowledgeable contesters to let me know if they can comply or

Message-ID: <19970129223110546.AAA276 at>

Due to low funds available this year (cash is tight), I am asking around to
see if anyone is in need of another high speed CW operator for the ARRL DX
CW contest next month.

I was part of the V31EV team last year.  2nd place North America in M/S
catagory.  4300+ Q's.   -  I was asked to go again this year, but airfare to
Belize was over $700 USD not counting food and lodging, that would put me
over $1000 USD and I just can't afford that much this time around.

I am willing to travel to most anywhere in USA or cheap airfare to Europe or
Carribian.  But I must know pretty quickly if you need me, so I can make
arrangements, etc...

Let me know A.S.A.P.

Message-ID: <n1357564289.76133 at>

Thanks for all the replies to the request for a 160 Quicky antenna.
You gave me some great ideas.

I thought the replies interesting enough to share. Sorry if you have no

First, my original post:

The ARRL DX  contests are coming soon.
I need a real simple 160 mtr antenna I can put up in one afternoon. We have
a 120 foot tower with 20&40 mtr monobanders and an 80 mtr vee. There are
also some low fixed 20 and 15 mtr beams for SS on it.

Any ideas besides another inverted vee for 160?
Or is that the best choice at this point?

Tim - NU6S
Here's what I got. Thanks to all who responded! 


Inverted LUs:

An inverted L is probably quicker and easier to put up and feed and
for dx it should be at least as effective as an inv-v at that height.
its also easier to run feed line to it since its fed on or near the 
ground instead of from the top of the tower.... unless of course you 
already have  the feed line in place.


Probably the simplest and one that I have found works well, is an
inverted L.  The wire length is 126.5 feet.  Start with more, and trim to
resonance where you want in the band.  Feed with coax at the base of your
tower, attach the center conductor to the wire, and the braid to a ground
rod, or the tower if it is grounded.  You don't need any matching network
at the feed point.  Take the wire as far up the tower, vertical, as you
wish (the more vertical the better).  Take the rest off as flat as you
can, but it doesn't matter if it slopes a bit.  The horizontal section of
wire acts more like a capacitance hat than a radiator.  If you have the
time to string some long (600 feet) wire at low level for a receiving
antenna you will hear better on that.  GL and look for you on the air.. 


Try and inverted L...You dont need a tuner, and they seem to work pretty
well. 70 feet vertical, and 25 feet horizontal should do the trick.  Maybe a
coupleof radials if you have room.

I have a "dirt-simple" inverted L. Feed it at the base of the tower 
with 50 ohm coax, no tuner, no matching network, "no nothin'". It goes up 
the tower for 75 feet then over to a handy tree.  Total length is about 150 
feet.  Three elevated radials attached to the tower about 10 feet up, 135 
feet long, anchored to steel posts at the far end (insulated from them).

SWR is under 2:1 from 1800 to 1950.  Maybe I'm just lucky?


Hi Tim- Try a simple inverted L with a single radial under its horizontal
component. Get a spool of 500ft #14 UV protected wire from Home Depot. Cut
127ft piece for the L. Run it up vertically as much as possible, then top
runs horizontallly, however you have to support it. We (6E2T team) ran a
single radial of 127ft on the ground under it (cut from same spool of
wire), connected to the ground terminal on UNIQUE (single wire) wire
tuner, which is also connected to a short ground rod close by. The L is
connected to the single wire terminal on the UNIQUE tuner.  The UNIQUE is
tuned for lowest SWR at freq (1830 for us in MEX as DX), then we connect
coax to UNIQUE tuner output, and run it for 20ft or so to the amplifier, or
"inside"  tuner if it tunes 160M freqs. This antenna worked really well over
salt water ground on beach in Ensenada, and we worked about 45 MULTs in 3
hours on 160M Friday night of '95 ARRL DX CW (which we won). Try it, you'll
like it.

An inverted L hangs off of a tall tower like that pretty well.  Run the end
of the wire up towards the tower, and the "horizontal part" can go at quite
an angle if you have to tie the other support rope to something low.  The
vertical part will then hang down somewhere between 30 to 50 feet from the

It may be hard to get the ground system you need in an afternoon.  8 radials
works ok, 15 pretty good, 50 works great, but you can chip away at this
gradually over days.  The inverted L will beat the Inv. V for long haul
stuff but an inv. vee at 120 feet is no slouch.


Your time limit probably prevents shunt feeding the tower and the
associate radial farm needed. That is most likely your best long-term

The inverted vee is OK, but are you looking for DX or domestic?

If it is DX you seek, why not support an inverted-L with elevated
feed and elevated radials?  This can be done in a day and is quite
effective.  I suggest you hang the L as far from the tower as possible,
i.e., from a catenary rope extending from the tower to a nearby
tree or something like that.

Other Ideas:

     How bout a full size vertical.  Top point near the tower, and then 
     pull the base out till the wire's taught.  Plop down a few radials.  
     We use this type of antenna at 4M5X with great success.  In our case, 
     the base wire is about 50' from the tower.  I modeled it, and there 
     was very little effect to the vertical radiation.


Try the "VNE Special", designed by W9VNE.  It is 5/8 wave long,
supported at the top of your favorite tree. (or tower).  Feed it at the
bottom of one of the V legs.  (doesn't matter which one!).  Connnect a
tuner at the feedpoint (of course, you should protect it from the
elements) with the wire connected to the "single wire" connection
point.  No radials.  Just plug in the coax to the tuner, and you're all

Won't set the world on fire, but it should crush an inverted vee.

Tim - I have an anv vee, apex at 75 ft. Works well enough for me for 
the limited time I spend on 160 during a contest (looking for mults, 
not runs). Also, good enough to work the VK0 last week.


Take a 120 foot piece of #14 wire up to the top of the tower, feed it with
coax, ground the braid to the tower and run the 120 ft. sloper at about a 45
degree angle and away you go.


Look on page 45 of June 1994 QST.  Its an article on elevated groundplane 
80/160 antennas with reverse feed.  Its very simple, and it works.  As a 
matter of fact, I'm the guys the author talks about later in the 
article.  I had just moved to the country before the CQWW and needed a 
160m antenna in a hurry.  

That antenna still works and is just an S-unit below my full wave 160m 
delta loop.

Tim: See CQ magazine Oct. 1996 page 34 for an easy 160 antenna.
If the tower is insulated and you have the room, check out N4KG's article on
page 45 of June 1994 QST.

If you can get the ends of the vee up in the air at all (around
sixty feet or more), I would go with the vee.  There are other
things you could do that might work better, but overall, you will
do okay with it.  It also will work on receive.


If I had a 120' tower I would probably (in order of Preference) do one of
the following.

1) Shunt feed the tower and lay in at least 15 to 20 radials.
2) Put up and inverted L and lay in at least 15 to 20 radials.
3) put up two 1/4 wave slopers (one toward the caribbean, the other towards
4) Put up and Inverted V

Sloper off the tower, pointed East. (Not enough points to your west to
care about.)
You already have the best possible antenna up -- your tower plus the beams
on top will act much like a 5/8-wavelength vertical, provided you do two

Install some radials.  (Note:  no climbing required!!!!)

Install a gamma matching section.  (You'll need to climb partway up the

I'm assuming the tower is grounded at the base and that any guy wires have
insulators in them somewhere near the tower ends.

There ain't no better 160 antenna!!!!  (Except maybe two of these, phased.)

The biggest problem is you'll need maybe 1300 to 1600 pf of either air
variable caps or high voltage doorknobs for your matching section.  Your
gamma 'rod' can be something as simple as #12 wire spaced a foot or two from
the side of the tower.  It may need to extend up the side of the tower
between 50 and 80 feet.

Trust me -- it's great.  I have 22 radials of varying lengths; 75 feet to
150 feet, as distance to property lines permitted.  (Ideally they'd be 130
feet long.)

Another way is a 1/4 sloper. If you use the 1/4 
sloper, don't worry about cutting to resonance. Just measure a 1/4 of wire, 
turn back a lot around the bottom insulator, and tune for best SWR at 
desired frequency. That's probably cheapest and dirtiest, and more bang for 
the buck than an inverted V.

I would make up some 80m traps, put them on the end of your 80m v, and then
add enough wire to make it into a 80/160m trapped v.  W6CYX went over to
W6DU's house and did this last week; it worked out to an extra 35' of wire
on each side of Eric's 80m vee.  The traps you can make yourself from a
short piece of PVC pipe (abt. 10" long x 2" OD) plus some RG-58.  If you're
interested, I can look up the dimensions and pass it along to you.  I've
made these coax-on-PVC traps myself and they work great.

Go with a "K5ZD special". It is a sloping quarter wave vertical with 
elevated radials. Several have copied it and works fine/lasts long time.


The heck with the tower. Try a balloon vertical.

	I have a much shorter tower (40') and have had good success with an
Inverted L.  Basically it is a 1/4 wave, mostly vertical radiator, with
a flat top.

There should be plenty of references in the ARRL antenna book or
possibly at the KA9FOX site.


In response to your request for a 'QUICKIE 160 ANTENNA' let me 
point you to an article in the August 1984 CQ.....

It is the W4TWW Coaxial Inverted "L"......

What it is, is 88 feet of RG-58 and 37 feet of twin lead (300 or 450 

Fed directly with 50 ohm matching or anything.....mine works 
quite well....just last night I broke a pileup on LA7SL in Oslo....2 calls 
using a barefoot TS850.....

More about the antenna and how I make it a 'QUICKIE'.....

Starting at the base.....I use a SO239 chassis mount connector and solder a 
Pomona mini 'bannana to BNC adapter' between the center pin and one of the 
corner holes....the ground pin soldered to center of the '239....You FEED 
THE SHIELD on this antenna.....
Next comes 88 feet of RG58 with a BNC connector on one end....(plugs into 
the adapter)...on the other end, the center and shield are tied together and

to both sides of the twinlead.....the other end of the 37 feet of twinlead 
are shorted together....

I punch a couple of holes in the dielectric of the twin lead and do some 
fancy (hi hi) tieing of nylon string to pull the end up into and over a 

When I have it hanging from a tree....I wrap 3 or 4 radials into the 
remaining 3 holes of the SO239.....I use electric fence wire...stretch them 
out....raise the antenna so the 239 is about a foot off of the ground...and 
feed it with a random lenghth of coax....what ever it takes.....

I have used several 'ALL COAX'  antenna's over the years and find them 
quieter than a dipole or sloper (all wire type) antenna...

This year I decided to take part in CQWW160CW from LY2ZZ contest station.
  I had been listined to the band several days before contest and the con-
dition seemed to be prtty poor!
 By calling CQ I started the contest.Rate of first hour was 103 QSO's.Most
of them were EU and just a few were UA9's. I made QSO with JA for mult during
the first hour.The rate went down to 83 next hour. The third hour I decided
to searc for mult 'couse it was so slow with CQ'ing.
Shortly I found some new mults: 4U1ITU, EA8EA, TA2DS, 4L5A, EX8W, GU3HFN.
I heard some USA stations and VE9AA but it's a pitty-they couldnt hear me!!!
  Again I started calling CQ making local QSO's with EU. UA9's called me
sometimes us well but most of my QSO's were worth just 5pts
  The first USA station I did QSO with was at 0139Z. Actually I wasted lot
of time away 'couse so many EU were calling him and he just couldn't hear
That was NH state. After that I started searching for mult again. I was quite 
happy with JY,EK,9K2,A7,EA6 in my log!!!!!
  It was so difficult but I got answers from NJ,PA,OHIO,FLA,NC,NY.
The condition was so terrible the first night!!!!!!
MY plan was to make as many QSO's as possible untill the sunrise.So-again
calling CQ. That was great to hear answers from TF3,7X2,CT,SV1.But still lots of
EU and USA stations keep on not answering!For a long time I was calling CQ
making 5pts QSO's, just time to time checking band and picking up every new
mult!I was pleased with SV5,KP4,4X4,8p,P4!
  The loudest signal from NA was VE1ZZ who called me and gave a new mult!!!
  So I finished the first contest night having 406 QSO's,72mult,and 14
USA/VE among them in my log.The last QSO was 0735Z and I went on my break up
till 1208Z

  Again just EU and some UA9's.None of mults from 1208Z till 2050Z!!!!!!!!!!!
Just latter I found UN7 and EZ4.Second night I made 29 JA's and total during
test was 31 JA's!!!
  At 2253Z I heard VQ9SS calling CQ and none of takers even he could be
heared so loud!!!
  I made firs USA station that might at 0111Z. Some more USA stations
appeared with better signals than first night! I could make QSO's with them
quite easier!
But when calling CQ I wasn't called by any USA station untill 0315Z
During that time I picked up lots of mults:
                      USA/VE: NF,GA,VA,WV,ON,IL,MI,IN,SC,WI,AR,IA...
>From 0315Z NA stations started calling me and I was glad to make them -lots of
new mults come to my log!!!So that second night I made about 67 USA/VE
  My next break was from 0800Z till 1030Z Hoping to do some mult from
Pacific again I started at 1130Z. I heared VK3AJJ,9M2AX but I wasn't heared
by them!!!
(it's a pitty!!!!!!)
  But anyway, the only Pacific QSO was KC6VW at 1449Z and it was last mult!
  I finished contest having 866QSO's (with dupes) and 99 mults
  During test I heard (but haven't made!!!):
I hope to do all of them next year hi hi!
 So thanks everybody who called me in test !

That means, ground mounted and elevated systems are quite even. According to
your tests no big difference. I was going to elevate my HF2V this weekend
but now I'll increase the number of radials instead. I will send this
message back to the reflector in order to receive another tips.

Thank you and 73,

When you run these tests, did you merely DISCONNECT the other radials?  
Or did you actually REMOVE them from the near field?  Could probably
make a lot of difference.

Got to play with a 756 today for a couple minutes. Looks very interesting.
Lot smaller than I thought. One VFO knob; whit a button to switch on dual
receive. Talk about a stocking stuffer.
