80-10 Mtr Hamstick Experiment?
 

Some zany thoughts on an 80-10 mtr shorty antenna:

1. Two 80 mtr hamsticks in a dipole configuration fed
in the center with ladder line & an appropriate tuner.

2. The same as above except with a 4:1 balun in the
center of the dipole. The low impeadance end of the
balun would be at the center of the dipole.

Either configuration would be placed 65 ft above gnd.
Is there any merit or possibilities concerning the above?

1) Why waste money on the balun?

2) If you have 65 feet run a random wire and tune it.

3) The 80 meter hamsticks are mostly turns of wire that radiate poorly.

4) Hamstick dipoles are always a compromise antenna. The two 80 meter
sticks on 80 meters will have very narrow bandwidth, very low radiation
resistance, about 4 to 6 ohms, and very low efficiency. They will not be
much better on the other bands.

5) Your secret weapons is: you have 65 feet so run a sloper and a tuner.

Marvin,

1. It'll work. Not very well, but it will work.

2. Why? It isn't needed and is just another point of failure.

Are there any merits or possibilities for either? Sure, just
depends
on how limited or restricted you are about antennas. Would
either be
preferable over a full sized antenna at a half or third of the
height?
Not even close! The 'rotatable dipole' may have some benifit
being able
to 'null' out signals, but I seriously doubt if it would be
worth it.

I was under the impression that a fair/poor hamstick
dipole up 65' in the clear is preferable over a 65'
random wire ant located between 2 bldgs?

Marvin,
I guess that would depend on the random wire, how well it
performs. I can tell you that an 80 meter HamStick isn't the
'best' thing going by a long shot, either in normal mobile
use, or as you described. You would almost have to 'work at it'
to make some random wire antennas be as 'bad'. Then again,
'some' random wire antennas won't work as well as the Hamstick,
which is normal.
If the two buildings you talk about are anywhere near 65 feet
tall, then neither antenna will do particularly well (also
normal),
and any other antenna less well than if it were clear of
surrounding
buildings/objects. I can't say what the differences would be
and
neither can anyone else. Give one of the two a try and see what
happens. At least then you'll have a basis for comparison.
