That RG-142 is great stuff. As test engineer at Harris I often had ten, 10
kW TX's on burn-in at the same time with the dummy loads near the TX. 20+
kW of heat generated by each was waaaay to much for the A/C and the plant
got really hot. I had to move the dummy loads 300 feet away into an unused
basement area and used ten lengths of RG-142. It lasted for years and only
burped once when a type C connector arced and left black soot on the
ceiling, and that was due to improper installation of the connector. The
coax got hot but never to a point where you couldn't grab on to it
comfortably with your hand. I retired years ago and to my knowledge the
over half mile of really good coax is still in the ceiling at the plant.

## RG-142 is rated for 10 kw CCS...@ 2.9 mhz...... and only
3 kw CCS @ 30 mhz. What freq were u testing at ??
## other RG-58 size coax that will take power is RG-303..
and also RG-400... both PTFE.
## 10 x 10 kw TX's = 100 kw of heat !
later... Jim VE7RF
