I was going to try to put up a antenna for the ARRL 160 contest and got to
hinking - why not use the zepp I use for 80-10 meters on 160 by shorting the
450 ohm
feedline , sticking my antenna tuner outside and running a few radials. It is
far
enough away from the house that I should get out well enough to have some fun...
I was looking at the ON4UN antenna book and this would be considered to be a "T"
antenna . I have about 60 feet of vertical 450 ohm open wire feedline and 44 ft
on
each leg of the antenna so 1/2 of the antenna would be not to far from being a
1/4 wl
Inverted L on 160.
I was looking for some tips on how to feed this so I don't have to stick my
antenna
tuner outside everytime I want to get on 160. I was thinking of doing the
following :
* Build a 2:1 UNUN and put it at the bottom of the antenna. The SWR is probably
close
enough that I could get the SWR down with the tuner (bypassing the balun in the
tuner
and feed via coax jack) in the shack.
* Get a variable air capacitor ( I think I need 500-800pf ??) and put it in
series at
bottom of antenna. Anyone have a source around Atlanta or willing to part with
one I
could buy ???
Anyone have any other tips/ideas???
Thanks, Jeff
ps : Condx were real good here last night. I heard ZD8A and several EU
stations Q5
with the antenna in the zepp configuration..
