[Amps] QRO Questions

[Craig]

Hi Ron

Times Microwave also makes a similar coax to RG142 called FBT-600. 
This coax was designed for high power jumpering. 

FBT-600 coax is flame retarding in nature,,, designed for running in ceiling and wall cavities. It has impressive power handling capabilities like RG142 and RG393.

I picked up a box of FBT600 jumpers at a hamfest, it came from a TV station. I chopped them up to make some 4:1 baluns.

   There is a PTFE coax about the size of RG-58 with less loss and more power handling
capacity than RG214 so what you mention is a lot more than probable.  (as is 1/4"
superflex)  I like the Times LMR products, while not as efficient as above, many are "direct 
burnable."  (polyethylene jacket)
