[Hallicrafters] Antenna Suggestion?

[Kenneth Laine Ketner]

Mike, I have had good luck with an “85/17.” You run an 85 foot longwire,
and put a 17 ft counterpoise on your rig ground. I have run the whole
thing outdoors with coax to a common mode choke wound with the coax on a
4 inch pvc sewer pipe piece - it is about a foot above ground. The inner
coax lead from this choke goes to the 85 ft. longwire which I run up
into the trees as straight as possible. Then I use an alligator clip to
fasten the 17 ft. counterpoise to the coax shield which goes to the
ground rod very close (less than a foot) to the common mode choke. One
can clip the counterpoise to a no. 14 wire going from coax shield to
ground rod, and run the counterpoise along the base of the outer wall.
Use cable ties to hold the choke together, and support the choke using a
wooden stick. With a good tuner (I use Heath 2060A), I can use this
antenna on 80 - 6 meters. Basically, the pattern below seems to work.

10 meters            counterpoise off
15 meters                                on
14 meters                                on
40 meters                                on
80 meters                                off

6 meters                 experiment

Some of the old tube sets may not even need a tuner.

This antenna is discussed as the “W3EDP” in PRACTICAL WIRE ANTENNAS
(pages 33-34), by John D. Heys G3BDQ, a small paperback available
through the ARRL bookstore. Adding the common mode coax choke was might
thought (which seems to work well), and the coax means no rf in shack.
Use of an ATU further insures against RF. This rig in a 30 ft tree works
as well as my ground mounted vertical, and sometimes better.
