[CW] High Power Coax

[sbjohnston at aol.com]

Biggest I've used in my radio stations has been 3-1/8" rigid coaxial line.  Dielectric is dry air or nitrogen.  Mounting and hangers have to allow for the considerable expansion hot days versus cold nights for hundreds of feet of this line.

Some VHF TV stations I've worked with had the 6-1/8" size.

 50 Ohm coax sections. The inner conductor is 6-1/8 inch hardline outer conductor. Big stuff. It easily handles 4 Megawatts peak power or about 360 kW continuously.
