Very interesting...all our sites are dense with RF from Public Safety radio systems 800, 700, VHF, etc. No problems in five years. I suspect it has more to do with how the RF connections are made than the LMR cable. Just my subjective opinion of one.
Actually it is the cable. My discussion with two engineers at TimesMicrowave indicated that it was not so much the dissimilar metals that were the issue, but the foil over braid and two somewhat independent shields. No mention was made of this being a termination or connection issue. As with everything, Your Mileage May Vary. I use the stuff in non duplex telemetry applications by the 1000 roll, not a problem. We have some on site in use for non duplex applications, but many well engineered public safety sites will not allow the product on site regardless of the use. My personal preference is a 100% copper shield obtained with any of the smaller superflexible Andrews and other products. I try to use ¼, 3/8 and ½ superflex for those duplexer to the radio and duplexer to the lighting arrestor runs. IMHO, nothing says 100% shielded like solid copper. 73 Daron N7HQR
