[TowerTalk] Antenna Modeling

[Dan Bookwalter]

In late 90's , I had a 40/80 combo , apex 70ft ,  ends at roughly 30ft I suppose I forget which order I trimmed them , but , got both bands working nicely on CW end , never modeled it ... but , from my perspective worked very well ... 
It was "aimed" at EU ... 
I know everyone is onto modeling everything,  I am in the camp of , put it up , give it a try , dont like it , try again ... 
We have lost so much of the "ham" part of ham radio... I used to , and still do , throw a wire out and see what you can do ... other than 160 and probably 80 , you can work a suprising amount of stuff ...
My first 285 countries were with a ta-33 at 18 feet , 100 watts , and no external vfo,  worked several new ones spinning the dial back and forth...

P.s. I miss those days ... oh , and chasing the Russians with the RIT during a qso because they drifted around so much (late 70's/early 80's)

If you have neighbors the answer is neither. Antennas like this cannot 
be choked to kill noise picked up on the feedline, so they tend to be 
noisy. You can't work 'em if you can't hear 'em.

Resonant coax-fed antennas with a serious ferrite choke at the feedpoint 
are the quietest antenna you can easily rig. That's the virtue of fan 
dipoles.
