[amsat-bb] Re: Best type of coax to use between preamps and antennas

Ron,

There are a variety of flexible, low loss cables. Over a 10-15 foot length the differences in loss would be inconsequential. Probably the most important factor is that it has excellent shielding, and preferably double shielding, to prevent pickup between the RX and TX bands. Over the years I have used RG-213, Davis Bury-Flex, LMR-400UF, and probably AirCom around the rotators. I have used the original "water pipe" 9913 only, but I suspect the modern flexible version would be fine as well. Even with heavy use back in the pacsat and HEO days, I have never had a failure of a cable, except for one of my bad connector installations where I did not provide proper strain relief.
