[SixClub] Recommended Coax?

[cboone at earthlink.net]

IF you can get some 3/4 in CATV hardline, use that...the loss is better than 7/8in Heliax at UHF (Even with the SWR loss added in)...You can use 3/4 to 1/2in brass compression unions to mate PL259s to the hardline. In flexible areas, you need something like RG8, etc...but for long runs that are tied down, 3/4in CATV line is great and dirt cheap!
