Bill:
I agree with Dan about the three dipoles fed from a common coax line.
That was my antenna system as a young Ham back in the '60s. It's a simple
design and is almost guaranteed to work as well as separate dipoles. I've not
tried a trapped system but can only expect weeping and gnashing of teeth until
you get the three bands to work compatibly with each other.

Bill: I think you are wasting your time with the trap dipoles. You can use
the parallel dipole designs which are much more efficient as well as
simpler. .....

Subject: [TowerTalk] Trapped in antenna trap confusion
Hello,
I seek help in resolving some confusion with respect to antenna traps.
I am an Old Timer, who has been passively active in Amateur Radio since
first licensed in my early teen years. Now retired, I want to pick up from
my all too short youth and recapture the awe, glory, excitement and
satisfaction of radio magic that comes from kit builds and home brew station
set-ups. Winter is now over, my K2 is complete, the J-38 key cleaned, and
my code speed is approaching a respectable 15 wpm. So, with spring in the
air, an OT's fancy turns to ............well, ummm, thoughts of
constructing some simple home brew antennas.
My bands of interest (until higher band conditions improve) are 75, 40 and
20 metres. .........
Bill VE2WMA
