Re: Best coax for short jumpers in repeater cabinet? It's easy just to use some practical rule of thumb guidelines for coax runs. One doesn't have to use ultra over kill coax in every application.
How long? - Length being enough to cause a loss, desired or otherwise (...and yes there is more than one case for a desired feed-line loss) Does the size matter? - Does the diameter of the cable make it practical to fit the application and are the connectors fairly easy to deal with in both size and price? Large RG-8 diameter size coax can become unwieldy in tight corner and space limited locations. Price? - Is the resultant purchase a good dollar to performance value and is the actual performance "good enough" for the application? One doesn't have to go high dollar overkill spec all the time. I'm also a fairly big fan of RG-233 Coax for many repeater system/equipment applications. RG-233 seems to be the ignored step child of the coax family, which means it's not instant shark bait every time it pops up on Ebay and the surplus radio world market. I found a fairly decent price on some pre-made RG-233 Coax runs on Ebay: Cable Assembly RF Coax 7 ft RG-223/U N-Fe to SMA Male Ebay Item number: 190175957842 My offer to the seller for 2/3 the asking amount was accepted and I now have a fair number of those lines in my collection at a much better than the $3.10 (Tessco) list price per foot. Not a bad deal if you want to take the plunge... cheers, skipp skipp025 at yahoo.com www.radiowrench.com "See you at Dayton!
