Mike,
My chart in the ARRL Handbook says RG-174 has a dielectric breakdown
voltage of 300 volts RMS. So in theory, it will handle 1800 watts at an
SWR = 1.0 (less at higher SWR) - but I would not trust it at much over
25 watts myself. I like to see a larger safety factor where
transmission lines are concerned. The ohmic losses may be great too,
that all depends on the length and the SWR.
73,

Will RG-174 handle 100W at HF/6M?
I am building a tuning bridge for my Nye Viking tuner, and will be
installing a relay to switch it in and out of circuit.
My K3 will transmit and receive through the NC contacts of the relay.
Mike
