The one point I'd make is that long runs of coax tend to defeat the purpose of using an amplified antenna.
Absolutely. I keep it simple: the antenna lives in a fishing rod holder on the rail when in harbor, with a short run coax of less than 20ft. No need for amplification, and these antennas do not need to sit high up.
Instead of amplifying, use thicker coax. The issue is parallel to that of VHF, where many have RG58 running up the mast. When the mast is 50ft and more, you'll do better with RG213. For reference: at least in my country, commercial vessels will not have their VHF approved if the cable is RG58 and cable length exceeds 65ft.
I use way thicker again to my WiFi.
