Antennas:   


146MHz -- Diamond Antenna mono band F23H 5/8 x 3, 7.8 dBi. height at base of antenna is 8 ft. tip height is 15ft + 8 ft = 23 ft

3.5MHz to 50MHz --> Inverted L shape wire -- 50 ft width, 8 ft height ( intended for NVIS ) at the end, it connect to MFJ 993B auto antenna tuner in water tight container, and ground of tuner is connect to 50 ft long wire laying on ground.

 

Automatic antenna tuner at base MFJ-993  inside of SOCKiTBOX  and 1:9 transformer UNUN

 

 

Vertical part of Inverted L  about 20 ft high.
