You will need a ground connection such as half-dozen, shallow-buried radial wires, between 10 and 20 feet long. Include any metal water pipes with the radials. An overall wire length between 100 and 150 feet does better on the lower HF frequencies and on the MF broadcast band. Between 40 and 100 feet does better on the higher frequency HF bands. They'll never get it. It's too simple. ---- Reg, G4FGQ w3rv ============================================== anyone have a good ideia to build a multiband wire antena? Carlos Poinho CU3FT |
