Well, as much as I would love to have a selection
of antenna's, at the moment, I have two only. An inverted "L" about
185' long and a newly constructed Dipole.
The dipole is 135' long and fed with 300R open
wire tuned feeder line about 40' long. It's about 9M high in the centre and
7-8M at each end. UPDATE 2006: I have moved house and no longer have this antenna
So far I have it erected only and I am trying
to feed it. Reading the Web, it seemed like a good idea to fit a 1:1 current
balun at the end of the feeder to allow connection via Co-ax cable (short)
to an antenna tuner.
I built a W2DU balun based on information by VK1OD,
using ferrites from Jaycar, Cat # .LF-1258
Testing showed........................

29th
Aug I fitted up my SG-239 auto tuner acquired
at a recent Hamfest. This tuner is basically a pcb with no housing at all so
needs weather proofing. I found a nice sealed case with a clear lid, from a
local electronics store and mounted the SG-239 into it, with SO-239 socket and
terminal posts for the antenna.
I
connected my Picastar and tried the tuner with low power. It tuned up in about
2 seconds on 80M and 40M. 20M was tried and also ok on 160M so it seems my new
antenna might work. Tuning around on 40M I heard a station calling "CQ
contest" and a dog pile trying to contact him. I called in also and was
very pleasantly surprised for him to call me back with 5,9 reports both ways!
