80-160 antenna for the small garden
I decided to make a trapped 80-160 meter vertical dipole with the feed point at 11 meters

Portable Vertical Antenna for 75m & 40
Designing the Antenna for 3.8 MHz With a regular vertical: 62 ft. mast is required Too long Radial length 60 ft. Too long Use a telescopic mast, 27 ft.and a 3 wire umbrella on top Radial length 27 ft. Same as vertical radiator height
Loop antenna for Rx on 80m
I have been experimenting with loops and found them to be very good Rx antennas. They have a useful null and provide a wonderfull drop in noise to bring the DX
Vertical 80m balloon antenna
The antenna could not be simpler - 1/4 or 1/2 wavelength of thin copper wire I used 35 SWG enamalled copper wire. This amounts to 20 or 40m of wire
The Double Bazooka Dipole
The Double Bazooka Dipole is a very efficient single band antenna

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
