Looks like the YCCC has obtained W2PV from what I see on the FCC ftp
filez...apparently K1XM is trustee....
I am glad to see this callsign NOT go to a 2MFM shack on the belt guy.

Subject: elevated radials and stuff like that
Message-ID: <199609250107.VAA16235@vixa.voyager.net>
Hi Jay,
I seek your input as you seem to have a good handle on 4sq's with elevated
radials.
I have a full size 160M tower, 25G, on an insulated base. About the base I
have laid down nearly 30,000 feet of copper wire to form a ground screen of
sorts. The wires, over 100 alone are #6 and #8 copper about 100' to 150'
long. Also I have laid out 25 rolls of chicken wire each 2' wide and 150'
long. As I added the wires, (all spare wire gets put to this purpose) I
checked the feed point with my MFJ and as expected the feed point of the
vertical dropped as more wire was added. This in an unsophisticated way told
me that the ground losses I started with may have been eliminated, or nearly
so. The feed point is now fed with a toroid un-un to match the 28-30 ohm
antenna to the 75 ohm 3/4" hard line. It works very well on 160. :')
Moving on....I recently (last summer) added an 80M 4sq array, supported from
this tower. It is a 75 ohm system (ON4UN). Each element is mounted on fence
posts which put the feed points about six feet above the aforementioned
ground screen. The phasing lines are 1/2" aluminum hard line with W2DU
current baluns at the ends. The thinking here was that I wanted to avoid
having the 160 vertical see the 80m elements as turned up radials. I would
have elevated the 4 sq further, but couldn't figure how to make the harline
survive swinging in the breeze.
The four 80m elements are spaced in a square 66' per side, straight vertical
and parallel to each other. Each has four radials the same length as the
vertical portion. (264/f)
The power at the dummy load with 1500W at the input of the phasing network
is only about 20 watts at the design freq of 3.75mHz. At 3.5 mHz, the power
at the dummy load goes nearly to 400W. I can add a couple feet of RG-11 to
the phasing lines and lengthen each radiator and radial and get the array
resonant in the cw band easily.
Hope this isn't boring you..... Given the current thread, what do you think
the effect of the rather large 160m ground screen has on the elevated 80m
radials? Maybe I would be better off is I just tied into this screen and fed
the 80m verticals at ground level without the current baluns. I still worry
that the 160 vertical would consider the 80m radiators as up-turned radials
and spoil its performance. Well, I really don't have the time or
instrumentation to investigate this system in depth. I was hoping you or
someone else on the reflector that is in the know on these matters could
offer some advice.
On 80M the array is directive, but not so much as I had hoped before I built
it. On the long distance stuff, sometimes I see f/b on the order of 20 dB.
More often, 10 dB. Checking f/b, f/s on close in high angle signals, the
differences melt away, 5 dB mostly. I think the array is performing OK, but
I sure would like to optimize it. Problem is, I don't quite know what to
change and more importantly I don't know why.
Once I hooked up a relay at the base of the 160 radiator so I could ground
and unground it remotely. I could see no difference in performance of the
80m 4-sq either way so I leave the tower element ungrounded. 375' of 3/4"
hard line away from the feed point is an Ameritron antenna selector box. The
un-used antennas are grounded at that point. Both the 4-sq and the 160 vert
are fed from this remote switch. Each with 375' of 3/4 hard line.
Sorry this takes so long to explain.....

Bruce

Would one of you guys who can make the FCC database dance check out how the
Tucker family of La Mirada, CA has done with new calls?
THere are 4 family members. All have 2-letter calls with their initials or
close (how tacky!). As of last year, they had 23 club callsigns among them.
How many of those club calls are now "cool" calls? Did they scoop all the
calls with their initials for suffixes?
I don't think they're contesters. I hope they get active. Think of the rate
you can have running Tuckers!

That is because N7ML is in zone 4 not zone 3, same zone as me. Funny move
all the way from Illinois to Montana and Im still in the same zone!
