[TowerTalk] Re: TowerTalk Digest, Vol 25, Issue 26

["George Lee" <geokr5c@cablelynx.com>]

Hi Yuri.

I have been turning a TH7, D3W and 2el Cushcraft 40M beam with a Ham IV for 
25 years.

I replaced the ring gear and added the super brake part.  I have forgotten 
what it is called.

Also have a 6 second delay on the brake release that I added myself.

Never run the rotation to end stop.

Ham IV hasn't been off the tower in 15 years.

When it gives some sort of trouble I intend to take it down and re-work and 
put it back up unless something happens that is not replaceable.

Good luck.

73, George

I have done no business at all with Champion Radio (and therefore have
no reason to think either well or ill of the company), but that has
certainly been no impediment to my participation here.

I did try to call the owner of qsl.net but no answer sent emails to let them

A few minutes ago I went to QSL.NET to take a peak at the 80/40 beam
built by a VE6, after seeing a post about it...  Now, Norton Internet
Security is informing me that QSL.NET (or someone claiming to be them)
is probing port address 80 on my computer trying to gain access...
What is interesting is that they got past my Netgear firewall and
Norton was forced to block them... Just a heads up to the gang...

Hi,
I lost breaks on my HAM IV for the 2nd time in 3 years.
All I have on it is TH6DXX only, so here's my question - is it too weak for
TH6? HyGain ad states it should endure such load.
Thanks.

Yup....I have had 6 el 15 meter beams on a 2 inch boom tear up the Ham
IV....upgrade!  The T2X should work fine.

Rich said he already did that -- see below.

Rich also said he made many phone calls that were never returned.
So if we accept his story at face value, he did his best. I don't
know Rich or Steve. Maybe Rich didn't listen carefully enough to
what Steve said he was selling, or maybe Steve didn't explain it
well enough. But there is clearly a problem between them. It should
remain between them, and they should resolve it like grown-ups.
When there are disagreements between people on a business
transaction, the standard way for good people to do that is to talk
it through and meet in the middle if necessary. Perhaps that's
what's needed here.

I also agree that to banish Rich from this list is childish and
arbitrary. If that reflects Steve's method of doing business, I
wouldn't want to do business with him either. And if I had sent the
stuff back by UPS once and it was refused, the vendor could order a
UPS pickup and pay for the return if he wanted it back.

I just finished erecting a hy Gain HY tower vertical which is 1/4  wave for 
75 meters and this one is set up to work only on 75 meters.  The only ground 
I have thus far is one ground rod.  The hard work is still ahead.  The Unit 
appears to work ok with resonance about where I want it but it hears about 
1.5 s units below my slopers. The SWR is very low but I am sure it will go 
up with a good ground field in place.   My questions are. (1) Will the 
addition of a good ground field have the same positive effects on receive 
that I should expect on the transmitted signal .
(2) Will the addition of a good ground field have any effect on the resonant 
frequency that it now has with only a single ground rod.  Van W4GIW

Hi, Tod and TTers;

Tod presents 'an elegant solution."  Furthermore, by optimizing the
length and diameter of the arm versus area of the vane, one can minimize
the wind loading on the tower and mast.

I recall that this aspect of antenna design and the calculations are
addressed in David Leeson's book, "Physical Design of Yagi Antennas."
I don't believe he includes calculations for any of the KT34 series, as
he does for several popular antennas, but he offers all you need to
calculate the wind induced torque.

I'm mising something here. Why would behavior OFF any
reflector shouldn't have anything to do with access to the
reflector?

I'm pretty sure Steve wouldn't do something like that unless
there was a huge misunderstanding.

Hello Van!

Congrats on your new 75 meter antenna. The HyTower is a real winner. I have 
been using HyTowers since 1977 and they work very well.
How well your new antenna works depends on several factors.
Ground radials (more is better) will provide significant improvements in 
gain performance.
The vertical will "hear" stations differently than your slopers as the two 
antennas have different vertical take off angle performance.
The VSWR may not go up much with a good ground system, but that depends on 
other factors as well.
Remember, a low VSWR does not always mean it is a good antenna.
The HyTower (like almost every antenna) obeys the law of reciprocity. What 
ever good/bad effects your ground system has on receive will also be the 
same on transmit as far as efficiency, gain, pattern, etc.

You can view 80 meter monoband HyTower installations at http://www.k3lr.com

73 and Good Luck!
Tim K3LR
