[UK-CONTEST] RG11 equiv foam coax?

[Kerr, Dr K.M.]

Hello all,

Planning a foray into 4 square building but have discovered that 75 ohm
10.3mm foam coax with the higher VF is not easy to get hold of!
This is for a 40m array so approx 40m required.
Does anyone know of a source of cable, type of suitable cable, solution
to the problem? Guess there are a few 4 square builders out there.

Replies off-reflector please.

Thanks in advance
