What a great group! I have one more antenna curiosity for my second QTH....I
work up north during the week and stay in my RV...I have the good fortune of
having access to the tall pine trees (>100' tall). I installed two antennas....
The first is a Cobra Ultralite Senior (140' linear loaded, fed with open wire
line). This rivals some of the best antennas I have ever had. Tunes 6-160m.
Because the span between trees is about 300', I decided to add a second antenna
in series to take advantage of the set up. This second antenna is a LW with a
total length of 300' or so.
I have compared the two and I prefer the dipole. The LW couples into anything
electronic and I hesitate to use it because it causes interference. It's also
noisier and is virtually the same as the dipole, in terms of signal output.
Hence, it's somewhat of a disappointment. Plus, my signal on 160m is anemic.
Thinking I can convert this into an Inverted L for a better DX antenna.
This would not be a resonant antenna for any specific band, as I don't know the
exact length and I don't have access to the horizontal portion for pruning.
I had to hire a tree climber to install these!! I just want to work with what
I have...
Here are my thoughts....Why not bring the vertical portion of the LW to ground
level (about 100') and attach to non resonant radials?
I can feed it with 450 ohm ladderline and terminate with 4:1 balun before
feeding it to a wideband tuner.
My question is, would I maintain the valuable characteristics of an Inv L and
would this be killer on 160m?
I currently feed this same LW into a remote balun, with an effective
counterpoise on the other terminal lug. Only thing is that it's not a ground
level and I have no radials, per se.
Thanks for the bandwidth. As always, your thoughts are appreciated.
73 and Happy New Year!
