Dipole for 14 MHz
The dipole is half the size of the usual full sized versions and is therefore about the size of a ten metre dipole

20 Meter Ground Plane Vertical Antenna
The portable 20m ground plan antenna is a basic wire arrangement with a wire radiator and three radials spaced 120 degrees apart
20m vertical aerial
About ten feet of 22mm copper pipe and about eight feet of 15mm copper pipe
20 meter Vertical with Balun
The balun is rather easy to make you need only a few items. This is a basic balun for a wire antenna, and it worked great for the flagpole
20m vertical antenna
Vertical antennas with a 1/4 or 1/2 wave sizing. Just a happy few build a 5/8 wave vertical antenna. This is remarkable, since the 5/8 has the lowest angle of radiation and has about 1dB more gain compared to 1/4 and 1/2 verticals

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
