Why not just set up a decent antenna on the house with a base inside. I get not wanting to drill holes but you would only need one hole for your coax. I just build a wooden shelf inside my kitchen cabinet. The power supply sits on the bottom then my base is on the top portion with a 2.5" hole directly under the speaker. I actually installed an electrical box and just made a hole in a blank faceplate but thats really not necessarily, you could just make a line size hole straight through and use silicone around it. If you own the house why not customize it to your liking. My antenna is attached to the side of the house and sits at around 30', this allowed me to use a 30' run of lmr400 to minimize signal loss.
