There seems to be a lot of varied experience with this type of cable. I've tried 9913 on a duplexer UHF repeater before & had the same noisy experience you had Derek. OTOH I have a 40' roll of LMR400 that I use on my 2 meter portapeater & it works just fine. A lot may have to do with what connectors are used & how they're installed. If the shield RF is kept on the inside of the foil, it will never get to the foil/braid interface, where the staticy desense is likely occurring. But this also means that the performance will be dependent upon how well the antenna at the end of the feedline is decoupled from the coax. If there is any RF current flow down the outside of the coax from the antenna, you're in trouble no matter what. Silver-plated braided coax & hardline don't have these issues since the shield material is uniform.
