Contest Antenna Questions

Tue Jul 4 14:19:26 EDT 1995

Thanks to W3LPL, K3WW, WB5VZL, W2UP,W3ZZ,KY3N, KM9P
N7IXG, WB5CRG for the responses re: antenna farm questions. 

All who voiced an opinion believe that my tall tower should be optimized for
20 and 40 meters, with a 40-2CD at 110' and stacked 205CA's at 100' and
50/60'. Given the low sunspots, I am convinced this is the way to go, and
have scrapped my original plan to put the TH7 on the tall tower. 

It is obvious that I don't have a second tower (yet) which is tall enough to
truly optimize 15 meters for DX work. The 155CA does work extremely well for
stateside at the current height (I had a 188 QSO first hour in the 1994 phone
SS while testing it). 

Having decided what to do with the 100' tower, I am considering options for
the other three (including growing one to 90/100'). 

Again, thanks to all who responded and I will surely advise you as to the
eventual antenna layout. 

By the way, the present 80M antenna is a quarter wave vertical. It works
extremely well here with the good ground conductivity. I am working on a 4
square, which hopefully will be done before the fall season. Last year the
160 antenna was a dipole off the 100' tower. This year I will have the same
or will shunt feed one of the towers.

I, too, have occasionally noted small arcing sounds coming from my towers
when there's lightning several miles away.  It must be cool to actually SEE
the charge flowing down to ground!

I believe this, and the two observations cited above it, are just graphic
examples of simple inductive coupling between the lightning and the ground
system of the building or tower.  

Nothing magic going on here...

One of you EE's out there - this correct, is it not?

I will now resume work on my CONTEST antennas.

Operated with a TH3 @ 50 ft from home.
525 Q's on 10
  3 Q's on 15
217 Q's on 20
212 Q's on 40  - 40-2CD
10 meters was open from the start, with last Q on 10 at 0434 Z.
Had opening on 10 a few days earlier to GI0KOW around 0400Z.  
CO was the farthest west Q on 10 meters.  Sure made it fun working
the new guys on 10.  Maybe work will allow a campout site next year.
