oh awesome, thank you! I shall have a look into this :)

edit: how important would antenna placement be? I assume it's not just like receiving an commericial FM music station signal in a building eh? I could mount it on the roof; but setting up a big mast would be an issue landlord wise! "As the crow flies" I'm fairly close to the airport

Should be fine to do an interior antenna at the distances you’re talking. Enjoy!

Sweet! Thanks so much :)

Half the transmissions come from airplanes, rather than the tower, so signal distance and strength will vary.

Any airborne aircraft are easy to hear, due to line of sight.

The tower and anyone on the ground are usually the trickiest signals to receive unless you're close to the airport.

Line of sight, so you'll probably pick up the planes fine but not the controllers.
