Today I discovered that I have had environmental ingress beneath the outer jacket of some ~8 year old LMR-400. What I saw was a white powder like substance between the woven shield and the foil. Also

Back in the early 2000s I had a long conversation with the guys at Times. The ultra flex on many of my jumpers had cracked after only a couple of years in the FL sun. His response was the ultraflex w

I find this interesting, especially Bill K4XS' comments. My comments... LMR400UF has a thermoplastic elastomer jacket that is good for "in excess of 10 years" outdoors. Most of the other LMR400s use

From the description it sounds like plenum rated coax... not for outside use. We've used LMR-400 Times , five repeaterss, so far so good, been seven years in the sun on the roof of hi-rise, lots of U

A loose, 3 turn coil of LMR-400 will do the job if properly supported. It acts much like w very large watch spring; loosening in one direction and tightening in the other with very littlr bending goi

I used DX Engineering DXE400MAX, and only one large horizontal turn. The cable experiences only bending, and no twisting. It's EXACTLY like Davis RF's BuryFlex400 but without the higher price and add

I have been using BuryFlex here for 7 yrs or so and it looks as good as the day I put it up. The "PE" type jacket appears to be the reason which is what the DXE4000 says it has. Has anyone else compa
