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
Builda 12/17 Meter Trap Dipole
I wanted a self-supporting rotatable dipole for best performance on 12/17 meter as well
Frame receiving antenna 80 m
In the construction of the magnetic frame antenna and its impedance match with the preamplifier, a PSV standing wave ratio of less than 1: 2.5 was obtained
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
