  • S-LM-400
Size: 10 ft
I should have read the description better. It is obviously made to mimic the standard LMR-400. I tried to find a datasheet but there are none available as this is a nonstandard coax. Given that I don't know the power handling of the coax. I had intended to use it out of the amp but hesitate to put much power through them. I will replace the coax from the 3 rigs and the line feeding the amp. I will find and order some LMR-400 cable runs. ... show more

  • Connectors are made cheap.
Size: 3 ft
Coax is not marked as to type and quality. Connectors are cheaply made. Will not cinch down when screwed on. They slip. Will not buy anymore gemek.
