  160 meters Band: DXing on the Edge

 

My transmitting antenna  is always the same since 1991.

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 to tune four elevated radials for the summer, but I never went back.

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 heard!

The problem is always to hear all the stations answering my CQ’s.

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