I use TMS LMR240 & LMR400 exclusively for 2 reasons.


1. the loss at these frequencies (27.185) is only .64 dB per 100 feet. I appreciate the advantages of using virtually lossless lines. Line attenuation is the killer, not VSWR.

2. where the rf shielding attenuation for conventional coaxial feedlines with a single shield conductor seldom exceeds better than > 40 dB, LMR240 and LMR400 are manufactured with a dual shield which provides increased levels of rf shielding attenuation to better than > 90 dB.. That eliminates a lot of "unwanted" coupling.
