Run coax to the roof with a bias-t fed low noise amplifier at the antenna providing enough gain to overcome the loss in whichever type of coax you choose. Much simpler and more flexible as you can switch out receivers, filters, etc inside your "shack."
Failing that, I would feed DC to the Pi via a passive PoE arrangement. This limits you to 100mbps, but the Pi isn't much more capable than that anyway. Definitely use 23ga ethernet cable if available (most cheap cat6 is), and use a "wall-wart" style transformer instead of a switcher as these are lower noise. Shooting to feed with 5.3v or so would be ideal.

The PoE hat is useful if you have PoE infrastructure already. If not it's relatively expensive and leaves some things to be desired.
Like one of these: https://www.amazon.com/Raspberry-micro-USB-PoE-cable-set/dp/B00T68D7S4
Requires a 5v supply with a 5.5mm barrel connector instead of your usual phone charger.
If you already have a poe switch, you can get just the Pi end - https://www.amazon.com/Revotech%C2%AE-Standard-Splitter-Ethernet-Connector/dp/B01H6JRBE0
