Review: I've been an amateur radio operator for 45 years and I know that if you are operating on UHF you need LMR400 coax. I operate a UHF digital repeater for DMR radio and I wanted to make sure the best coax feedline to run to the top of my 50 ft tower. After looking at all the radio sources I could find I came across the listing on desertcart.ca. This is the best price I could find for LMR400.
Review: These are great low loss cables with solid 75 Ω "N" connectors!
