I'm not sure that there's a PA on the market that actually has a high quality LNA built into it. From what I've seen, the amps with built in LNAs seem to have mediocre specs. Your best bet is probably a separate PA at a convenient location along the coax run and a mast mounted preamp (the SSB Electronics preamps can handle 100w RF-switched and the ARR preamps can handle up to 25w or 160w RF-switched (depending on the model)).

What is the best mast-mount PA / LNA on the market these days.
Our old TE Systems amps are now over 15 years old and have only mildly been protected from the weather.
Since I am not hearing as well as some other stations, maybe it is time to replace/upgrade?
The TE systems had a low noise preamp for receive and 100W amp for TX.
We need the amp because we have 150’ of coax to the roof.
Do they still make ‘em?
So whats out there?
