50 mhz halo antenna horizontally polarized
The basic horizontally polarized antenna is a half-wave dipole. It has a radiation pattern that exhibits lobes and sharp nulls

2 meter halo antenna
The antenna I show here is my third generation design. The goal for this next design was to build something that I could get a good SWR
Project 2m Halo for 144 MHz
Polarisation is horizontal while the radiation pattern is omnidirectional
4m Halo Antenna
Using aluminium tubes from 4 and 6 mm The boom (H) is made with an aluminium profile 10/10 mm square section
50MHz halo Antenna for mobile
Six Metre halo be centred on 50.125 MHz so that it can work efficiently in the DX segment of the band but will still be effective on 50.150 MHz and above
