I use good rg-213 for all connections except Beverage or other RX antennas
that I use RG-6 for.

Im re-cabling a 4 transmitter station and am looking for feedback on what
you are using for interconnect coax after your amplifiers?  I'm using double
shielded RG8X for the low power connections to the low power bandpass
filters then to the amplifier inputs.  Looking to see if good quality RG213
/ RG8 (95-98% shield) is ok past the amps to the high power 4O3A filters or
should I use something like LMR400 / BuryFlex for those connections to keep
down the potential inter-station interference?

Thanks...
