[amsat-bb] Re: Best type of coax to use between preamps and antennas

Did you diagnose what your problem was ? Water in the coax ? Where is  your 
preamp mounted ? If very near (10 feet) the antenna you can use RG8. If you 
feel intimidated by N connectors (many folks are), Henry Radio and others 
sell a two (2) piece N connector that is installed much like a PL 259 which 
you have probably installed many times. Check out Henry Radio on Ebay. If 
you need more info on this email me direct. I think they get around $4 a 
connector. A short run (10 ft) of RG8 at 432mhz or 144mhz is not too 
prohibited, in my opinion. Or you can have somebody put together a jumper as 
you have noted. Self reliance provides better quality control in my opinion.
