[Antennas] Hanging more wire.

2004年2月17日 17:56:29 -0500

To hang more wire, or less wire?
I have an 88' ladderline fed dipole, up in the trees about 45'. It works
pretty well on 40 & 20, but doesn't tune well on 75m, being a bit short.
I'm using the internal tuner in my '746, about 10' of rg213, 1:1 balun, and
probably 60' of 450ohm ladder line.
I would like to get better results on 75m, and still use it on 40 & 20. [I
have a vertical that does a decent job on 10 & 15]. What I would like to do
is extend the dipole into a loop for 75m. But, living on a 100'x60' lot, I
just don't quite have the real estate. What I can do is make a loop that is
about 200' [at the same 45' average height], or I could lengthen the current
88' dipole to 130' and give it a "Z" shape.
I could also go with the 200' loop, and add a 'stub' of ladder line to load
it for 75m....
What do you think? Hang more wire, or less wire?
Any suggestions greatly appreciated:-)
