Ok here is what I have so far...
Uniden BC72XLT Scanner
10ft PVC Mast on roof
From what I gather I am relatively equal in elevation to BNA and it is roughly 11 miles to the SW (my house is located under the ILS runway 20L).
I can pick up aircraft in the air around Nashville fine and clear and I can hear tower, ground, and approach at BNA but with a decent amount of static.
How can I improve the signal as to get higher quality sound from BNA?
