If the coax is routinely getting warm due to the transmitted energy being
applied to the coax, and the load (antenna) is properly matched,
then it's the wrong size coax for the application.
If your coax is getting warm under the conditions described below, you are
losing power in the coax which
could result in a fire safety hazard (not to mention lost QSOs). I'd check
the VSWR to be sure it's as *flat* (as close to 1:1) as possible.
That will ensure any heat problem with the coax can be isolated to a
component in the line (connector/switch/adapter/lightning arrestor, etc).
If you still wish to operate this way, move up to higher power-handling
coax, such as LDF-4, etc.
