Topband: 160 meter vertical

[Milt Jensen]

Bruce,

Our 160 Meter antenna at XZ0A was 40' of Bangkok 25 (Rohn knock off),  a
short insulated section, then 100' of Bangkok 25.  The top 30' to resonate
the Ground Plane was made of three sleeved sections of aluminum tubing.  12,
1/4 WL insulated elevated radials completed the antenna.

The results speak for themselves.

Milt, N5IA
