[Amps] Coax needed

[Bob Maser]

Do a search on Google for coaxial cable specs.  There you will find a 
website called RF Cafe. It is the first one on the Google list.  You are 
looking for ST(Solid Teflon dielectric.  303 is not the only one that will 
fit your need. There's 142A/B, 141A, 400, 401, etc.
