Agreed.
RG-400 works well to. The only difference between RG-142 and RG-400, is
that RG-400 has a stranded center conductor. RG-142 has a silver plated
solid hard drawn copper center conductor.

The 50MHz power average rating for RG142 is several kilowatts, why do you
think it is inadequate?*If it is a balun problem it is most likely connection
related.*

My six element 6M LFA is showing a high SWR and severe loss of receive
signal. This happened this afternoon as I was working the band with 500
watts from my KPA500.
To this point, the antenna was very nicely matched with a 1:1 SWR over
almost 1 MHz of bandwidth. The antenna is home brew and I made the matching
balun per the instructions from K9YC using two toroids with six turns each
of high quality teflon insulated, double shielded silver braid. I think it
was RG142 purchased new from a reputable vendor in Tennessee. It has worked
perfectly at the 100 watt level for three or four years. I had looked at
the specs on the coax and thought it would be good for 500 watts.
Evidently not.
