Howdy, and welcome to the forum.
A couple of thoughts. Depending how the tower is attached to the house, you could have a "hum" conducted in when it's windy. In some houses, the wind makes enough noise already, so you probably wouldn't notice (like my house). Just something to think about.
I've never been keen on climbing TV towers (so I've never done it). You might want a way to tilt down the tower with hinges on 2 legs (un-bolt the third). That implies a cable to haul it up and down, and a safe way to detach it from the house before lowering it. Can be done, just need to plan it carefully.
Keep letting us see how the project goes. Lots of us take an interest, lots will have helpful suggestions.
