Here's two photos behind my modified antenna switch. www.w0btu.com/files/misc/F-connector_1500+W/
Towards the red antenna switch is a short, brown-jacketed section of RG-59; then a double-female F barrel; and then black F-6 which goes outdoors to my transmit antennas. The brown RG-59 gets *slightly* warm on continous 1500W carrier, but neither the F barrel nor the F-6 is above ambient temperature. BTW, F-6 (the CATV version of RG-6) has the same power handling capability as RG-213. 73, Mike www.w0btu.com On Fri, Dec 7, 2018 at 8:22 PM Mike Waters <[email protected]> wrote: > Hi Tim! > > That's an excellent thought, but some people do it. > > As a side point, I run 1500 watts (>2000 into a dummy load!) *through F > connectors* and F-6 coax.
