Thanks for all the inputs, much appreciated.
Maximum run length for the 75 ohm cable would be 1/4 wavelength on
28MHz. For other bands just a couple of feet as a series section
transformer in each case.

Martin, Its really first about expected loss for 30 Mhz - isn't it? Why put
1KW into a cable that has loss of 1.8dB per 100 ft? How long a run are you
planning?

Definitely not feeling the Google love today!
Anyone have an idea of the 30MHz power handling capability for RG6A/U and
Belden 9104?
I have some RG59A/U as well but having seen RG58 melt I'm not inclined to
try it at 1kW.
Thanks
