Hi Gang,
Here's a funny thing. I have just replaced my two parallel connected
dipoles (one cut for 80, the other cut for 40, connected together at the
apex and fed by a 1:1 balun and RG58CU coax) with a double zepp with
just one set of radiating elements cut a little longer than required to
resonate on 3.6 MHz, and fed with 450 ohm balanced line connected to a
4:1 balun just outside the shack and a short length of RG58CU to the K2
with KAT100.
The apex of the new antenna is some 12 feet or so higher than the old as
I now leave my wind-up tower fully extended. (Extended height is about
45 feet). Seems to work well, except that I noted considerable broadcast
station breakthrough on the 80 metre band that was not experienced with
the old dipoles. However, when the Tune button is held and the KAT100
does its magic, the breakthrough disappears.
Curious.
