Thanks Grant. In a quick search, I found RG179 on Pasternak's website,
but didn't see a relevant power rating at HF. Looking at Belden's
datasheet, VF is 0.695, so a bit more shortening of the feedline will be
required as compared to LMR200-75.

Another coax choice for 75 ohms is RG179, TFE + SCCS conductor +
silver shield. Slightly less diameter than RG400. I've not had SCCS
creep problems in dozens of QRO chokes I've made with 50 ohm SCCS
RG142, but if buying new 50 ohm cable the stranded RG400 is the better
choice. Belden says 1250 watts at 50MHz for the 75 ohm RG179, so for a
160m or 80m 4 sq probably has lots of headroom. 179 is available on ebay.
