I found my RG58A/U at a local radio supplier called Walker Radio. It is also available an other GOOD radio & electronics supple stores. I bought Mil-spec stuff in a 100' section. It wasn't too expensive, and I haven't had any problems with it yet. I also bought a good quality coax stripper there. Another excuse to by a neat tool!! Walker will ship whereever you like.
