RG-6 used for satellite TV has much lower loss than RG-58,
and is much cheaper and easier to work with than Heliax or LMR400.

Thanks all for the comments and suggestions.
Re my contemplated cable choice, my interest in using Heliax is primarily driven by
shielding and to a lesser extent phase stability considerations. (I also happen to have
some 1/2" Heliax and LMR400 on hand.) I'm currently using approx 70 feet of teflon
thin net (RG58 style) ethernet cable which I believe is less than optimal. I expect
switching to 1/2" heliax would also cut the cable losses by at least 10 to 15dB or
so which would be helpful if the new antenna has significantly less gain.
I'm not relishing installing either Heliax or LMR400 for this application but
I'm thinking if I'm going to buy a better antenna I should upgrade the cable as
well.
