The 1.5 kW PEP is at the amplifier output. That has been clarified with the FCC multiple times. Tuner, feedline, antenna system losses are your problem. You are diminished by those losses unless you

It is important to understand one's adapters. An F connector in the outdoors absolutely needs help for sealing. Also the female F connector has a built-in problem which is due to its diminished size:

Modern toys, that's what happened. But there are some emerging, very efficient antennas where the old methods can't possibly tell you enough to know what to do to tune it to an efficient spot. They h

Oh yeah. SWR is sooo great when everything is lossy as all getout. More and more radials will show you where it's actually tuned, for sure. As to tuning method, text on ma160v at DX Engineering says

Be careful to never, ever use THHN (with insulation NOT stripped off) outdoors. Also personally, I would never use it for RF transmission line. Do not confuse Z0 with efficiency. What part of the Z0

Really not much to learn. UV and likely outdoor wetness turned THHN into a MEASURED linear resistor at RF. What IS complicated is how so many clearly have some kind of stake in it NOT being true. Mea

Stripping insulation from a 500 feet spool of #12 THHN from a big box store is easy-peasy. Once you've seen it done, you'll kick yourself in the butt for ever buying bare wire from the online stores
