[QUOTE="Jason Glass, post: 68029, member: 2167"] Re: Best coax for paddles Hi Silas, Thanks for clarifying your requirements. At 25ft., any of the UF or F varieties of LMR-400, 9913, LMR-240, or plain RG-8X would work nicely and be reasonably flexible. The UA874 is an LPDA with an inherent 6dB of gain (over a theoretical isotropic antenna) when the on-board amp is set at 0dB gain. With 25ft. of low-loss cable, the lowest setting of 6dB boost is too much total system gain (12dB) for optimal performance, since it also boosts noise and undesirable signals. It also causes receiver desensitization by slamming the RX front end with signal. For those not aware, on-board antenna amps should be used only to make up for calculated cable losses and never as an attempt to extend the "over the air" reception range of a system. [/QUOTE]
