[Boatanchors] Coaxial cable question

[jeremy-ca]

For long runs to the 4 towers Ive been using 3/4" to 1" CATV hardline since 
the late 70's. It is used here up to 1.3GHz.

It has the lowest loss for a particular diameter and it was also free when 
the installation crew left town upon completion of the system.

For microwave Im using 7/8" Andrew Heliax, also freebies when a local 600' 
tower was replaced, since their connectors are rated for those frequencies.
