Gentlemen:
I need some advice on a project I now have time to undertake. Some good =
info at this point could save a lot of tower cranking. (including =
"forget it.....no free lunch", hi)
Presently I have a 60 ft tower with beam & use a sloper wire along with =
loaded, elevated radials for effective 160m work. Growing trees are =
forcing removal of the sloper wire, so am looking for another way to =
top-feed my tower. I like top feeding because the current is higher =
above ground. This gives a better shot over high, thick trees & I =
understand that the further away from ground the current/radiation is, =
the less loss to ground I will have, not having a good ground screen. =
(The tower is mounted on the side of the house w/ half-acre lot.)
Per the GAP patent, a .68 X 1/4 WL length of coax coiled & shorted on =
the far end , will provide a near lossless, non-radiating element for =
the RF to push against. The bottom half of the antenna would then be =
the top loaded tower plus a set of four elevated radials, with lengths =
adjusted for resonance.
Will the beam, working as a capacity hat, function correctly, connected =
to the mast & tower only a few feet below the feedpoint? Any advice on =
this proposed setup will be appreciated. I realize this is eccentric, =
but experimenting with space-restricted 160m antennas has become =
fascinating to me!
