What coax is recommended to reduce loss to a minimum,and to feed a multiband beam with a 2kw amplifier. Hard line excepted due to cost. Regards Ross ZL1WN I needed conventional low loss coax on the job a few years ago. Boss was paying for it, so I was not pinching pennies. Best I could find was the Times LMR400. As I recall, the center conductor is #9; so, it may not fit some brands of N connectors. Unlike the 9913, this will not soak up water. The loss at 50 MHz is 0.9 db, vs 1.6 db for 213 (100 feet). I know you want 20 meters, but 50 MHz is the lowest frequency I have any numbers for. LMR400: 300' at 14.2MHz with VSWR=1.5, loss~=1.5dB Tam/WB2TT -- |
