[GCARC] Recommendations needed

[Kenneth Bozarth]

You did not mention your budget.

A 40m dipole would fit diagonally in your back yard. You need at least one
support in the middle of the yard for an inverted V, or a support at each
corner for a horizontal regular dipole. Your chimney could be one support.
Arrange pulley so you can raise and lower it. If that fits, then add other
bands in a fan dipole configuration with one feed line. A vertical is also
a likely success for you to cover 40m. If you can lay or plant lots of
radials at the base, it will work better, unless you get something like a
Cushcraft R8, which needs no radials and is very efficient. I have one.
They are not cheap, maybe $600 or more by now. It must be mounted on a
10-12' pole that has a substantially strong tilt base and it could
bracketed to the house for support. No guy lines are required on the R8
when standing alone. Otherwise, a trap vertical will work, but with at
least a dozen radials on or in the ground, which can be as short as 20' or
so. Any of these verticals must be tuned for the end of the 40m band you
like, CW or SSB. They are wider on higher bands

For 20m and up, for a chimney mounted beam antenna there is the Hex beam,
which works well at low heights and is light. Actually, at 35-40' above
ground, any beam antenna will work. A Cushcraft A3 for instance. To cover
40m, I believe there is a 40m kit for the Hex beam and a rotatable dipole
for a Cushcraft type of beam.

One last suggestion is the Cobweb antenna which is multi band and omni
directional, also very light, great on the chimney.

For mobile, Ham sticks are cheap and work very well but on 40m they are BW
limited, need to be tuned where you wanna operate. Fairly wide on 20m on
up. For more BW on 40m, a screwdriver antenna is good but expensive. I use
a Diamond SD330, which comes with an up-down switch box. They are about
$350 or so, the cheapest screwdriver available. The beauty is that you can
band switch without getting out of the car.
I hope this helps.
