A portable vertical antenna for 160m
Having had some success with short 8ft long mobile aerials for ground-wave contacts on 160m, I was intrigued by the idea of making something a little larger for portable use

1.8mhz only 40 meters

160m Vertical 18m long spiderpole
Although this antenna is short for the 160m band, with its top-hat loading it is still very efficient

The inverted L antenna
The dimensions of the antenna are clear from the drawing. With this size, the antenna resonated at 1850kHz. Using a 12.5 meter telescope, the radiator impedance will be around 12 ohms, but the overall impedance will also complete the earth's impedance. If only 2 or 3 radials are used on the ground, the antenna can be powered directly by a 50 ohm coaxial cable


Take off angle of horizontal antenna

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane

A remote antenna switch
