When you are doing the coax loss calculations, don't just assume a matched load. I don't know what antennas you will have at the end of the run, but is it possible they might have a VSWR of 1.5:1 or even 2:1 at the band edges? That would increase the loss over the matched loss. At some point, open-wire feed line with matching transformers at each end becomes a viable option. 73, Steve G3TXQ _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk |
