N connectors by Huber&Suhner for example are rated 5.2KW@20MHz, 3.5KW@30MHz, 800W@1GHz etc. Amphenol specifies a peak power of 10KW no frequency given, so certainly low frequency only. 73 Peter Notic

For that matter frequency can't be high or low... That's the wrong measurement... It's actually just more or less often, right? Something being high is relative to the observer. _____________________

For a long run down a tower, you need to tape the cable to the tower at about 3 foot intervals to stop things moving. For a crank up, fold over tower, my recommendation is a 5/16 inch diameter 'messe
