4-Square Info
Band - 80m
Phasing system - Comtek
Bernard first setup his 4-square in 1998 and it is only operational during the winter months as he is using a cow pasture field. 
All the elements are free standing and home made using TV mast surplus and a military whip with linear loading.  Each vertical is around 50 feet high and individually tuned to around 3.750KHZ and the whole system is resonant at around 3.780.  Each vertical has 50 radials on the ground.  The verticals are fed via 75 ohm CATV coax and a unun.  The main feedline and control cables are around 150 ft long and Bernard has a remote relay switching system that allows him to switch between the SSB and CW band segments.
