  160 meters Band: DXing on the Edge


My transmitting antenna  is always the same… since 1991.

( Until 1990 I had an old shorter tower with an ”Inverted L”  described here )

A self supporting tower, 24 meters high, with a top loading 15 m. yagi at 28 m.

It is shunt fed with a gamma rod, tapped at 18 m. ( right on the photo) and a vacuum

Jennings capacitor. See all details of the Gamma Match  on this PDF file

The gamma feed was calculated with the help of always remembered Earl, K6SE.

After using in the first years about 60 radials, which had to be taken away in the spring

season, I tried four elevated radials for the summer, and I never went back.

They have been tuned as two crossed dipoles, trimmed to resonance on 1.830 KHz,

and suspended  from the tower with nylon ropes to freely walk around.

Of course I agree on the better efficiency of a wide on ground radial system, but we

have to live with some constrains and, as a matter of fact, I always worked all the

DX stations I could hear (295 DXCC countries on 160 m.).

The shorter rod on the left side of the tower in the photo is the detuning loop. See here.
