Antenna for 6M 50MHz
A double dipole fixed on a boom in the shape of H, which I will call cell. Each element 2 per cell is controlled by gamma match synchronized using a phase shift line

5el Yagi for 50Mhz with a 3.4Mtr boom
This antenna has been redesigned and represents what i beleive to the the ideal boom length for an OWA direct feed 50Ohm Ya
6 meter SLOOP
Omni-directional, and horizontally polarized. Copper is the best possible electrical conductor at normal temperatures, next to silver
70 cm 6/8 Element Beam
Antenna for 432 MHz and built it for use as an ATV receiving antenna
50MHz Power Splitters
The use of power splitters and combiners is widespread in amateur radio but the design of these circuits is often considered to be a black art
