- In general, RG-numbers are not a specification for coax. Rather, they define little more than the characteristic impedance and approximate physical size. This has been true for at least 50 years. The

- That will work great. That's what I use. Try to find some decent UHF female connectors for either the LMR-400 or RG213. Or use N type connectors. Seal them up well! Remember to make your last wrap of

- Hi Terry, Flexibility has to do with the mechanical characteristics of the cable... Outer Jacket: PVC is softer and therefore more flexible than PE. The trade-off is it's not as UV-resistant.Shield:

- I always thought a top connector was a good way to ground the coax to the tower at the top. It also makes it a lot easier to replace the loop if need be. 73 -- Larry -- W1DYJ --Original Message-- Fro
