50 MHz Omnidirectional antenna - Horizontal polarized omni directional 50MHz Antenna. This antenna is intented to use in a contest station as a second system beside the stacked yagi beam system. An omnidirectional systeem can be an advantage when it comes to short openings on wich the operator must react quickly.

EggBeater Antenna for VHF UHF - This antenna was conceived mainly for high-speed digital transmission via satellite. The antenna is made of two full waves loops , mounted at right angles to each other. Then coupled together, 90 degrees out of phase over a horizontal circular reflector. With this configuration the antenna is omni directional and circularly polarized.
