160 meter vertical antenna's base loading
The following pictures show what my 160M vertical antenna base loading and matching coil assembly looks like. Yes, I managed to shoot a line up over one of my HUGE about 135 feet tall trees. Then I pulled up about 125 feet of wire for the antenna itself.

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
