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.

(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.
