I was amused that in the middle of all this discussion about running excess
power, there was a posting which referred to the "ON4UN mod" to the FT1000
which prevents you from smoking the sub-receiver when it is attached to a
separate antenna. How appropriate.

OK, guys: I confess that I recently went into a diner and ordered
and ate a SOFT-BOILED EGG for breakfast, and on July 4th in the evening, my
daughter & I set off SPARKLERS in the back yard. (Believe it or not, both
activities are illegal in the Police State of New Jersey). God, I feel

Subject: Ground Plane Height
Message-ID: <9407151331.AA389851 at rs2>
I have used a ground plane on 40 meters for a couple of years with
very good results. It is elevated only 20 ft and has 8 radials drooping
from the base. I had this same antenna elevated about 12 ft at one time
and it seemed that it actually performed better there - I'm not sure
though. My question is: Is there any information out there on what
height off the ground you need to be for the radials to start looking
like the ground? I think I could manage to get an 80 meter ground plane
up 15-20 ft (maybe). By the way, I am talking about fullsize 1/4 wavenlength
antennas, not loaded ones. Another question: would it be possible for a
50 ft (or so) top loaded vertical to work well on 160m in a ground plane
configuration? Say, elevated also about 20 ft.
BTW, the reason I think I was happier with the 40 meter ground plane at
a lower height is because the radials were more horizontal, giving me
closer to 50 ohm match. Probably didn't actually radiate better.

Randy - I have a 20 ft mast with about 8 ft down in the tower at the
moment. I am getting interactions between my TH7 and 402CD and want to
put a few more feet between them.
If you think of the mast as a vertical see-saw, and the thrust bearing at
the top of the tower as the pivot point, all lateral (tilting) forces
generated by wind load are tansmitted to the rotor.
Since I will be increasing the moment-arm by extending the mast above the
thrust bearing, addtional force on the rotor concerns me. Putting a
second (not third) thrust bearing a few feet above the rotor will absorb
Makes sense to me. If I'm missing something, let me know... 73 Barry

But what's your point Randy? You didn't make one.
Sure, my allegation may have been unfounded. I've never been to W5WMU's
station. I didn't have to. I have a pretty keen knowledge of HF
propagation phenomena combined with lots of on-the-air experience.
I believe top contesters, even without the theoretical knowledge of
propagation, know what's going on around them (propagation wise). They
know where the band is open to and they know what kind of range of
signal strengths to expect, given the strengths of others on the band
from similar geographic regions.
Is this perfect? No. Does this mean W5WMU was surely running very high
power? No. Nothing's perfect, Randy.
But sometimes we have to shake up the troops in order to get some
useful discussion going. That was part of the reason for my message and
my tone. I've never been one to slam others without a reason.
It seems that only Dave (WX3N) and perhaps a few others have addressed
the real issue here.
What if W5WMU really does run very high power? Just because he lives in
a "propagationally disadvantaged" area, does this give him the right to
be 6 dB louder in Europe on the low bands than his peers in 4 and
5-land? I don't think so.
True, he's got probably the most impressive set of antennas I have ever
heard or seen. I was floored and impressed when I read that. And it
makes me think he doesn't run as much power as I originally thought. But
people are allowed to speculate in a forum like this.
Only through peer pressure will we stop the kinds of things that we all
have agreed at one time or another are ethically wrong.

Sounds like whining to me. Why did you move back to W1-land? So you
could have an advantage in DX contests. At least that's a legal
and ethically acceptable reason. There still remains no excuse to run
illegal power in contests.
Hey, if you really want to win, guest op from an area or station where
you could win from. You know how to do that, Randy. So do most of us.
But still, running high power is ethically wrong, not to mention against
FCC Rules and Regulations.
If W5WMU truly doesn't run very high power, my apologies to him.

Yes, but did you inhale?
