How far from the field are you? Having a metal roof, I was forced, gladly, to put a j-pole outsude and high. Wished I could get about 6 more feet in hight, but its above the quarter wave dist from the metal.
If you can swing it, getting a pole outside and high should get you great reception, already receiving field ground traffic and the transmitters from the attic. Plus, it's alot more fun having a huge antenna attached to the side of your abode rather than hidden, I would think (huge grin)....
