Peter said: >Is RG-174 adequate for the power levels encountered According to the Suhner catalogue, RG174 is good for 150 watts at 30MHz when matched, with a loss of 15dB/100metres at that frequency. Power handling goes up as a straight line on a log frequency/linear power handling scale as frequency goes down - 450watts at 10MHz. Attenuation goes down linearly on log dB/ log frequency scale to 9dB/100metres at 10MHz. hope this helps - looks like the answer is yes, OK, provided the SWR is reasonably low. rgds Peter G3RZP |
