Placing the antenna inside an attic behind trees will yield the following phone call 95% of the time:

Caller: "Hey, my reception is great until the wind blows or it rains. What's wrong with your antenna?"

Tech Support: "Hold please" ... goes and bangs head on wall and returns "Thank your for holding. Is the antenna behind trees?"

Caller: "Of course it is, that was the easiest spot to mount i"

........

Every day occurrence, multiple times a day....

Avoidable mistakes are just that, avoidable. Placing a UHF antenna behind trees rarely turns out well and it's not due to anything that the antenna does or doesn't do. Placing the antenna in the attic compounds the difficulty.

I'd strongly recommend a closer survey of your home to see if you can find a spot where a small, unobtrusive antenna may be mounted in a spot that offers a clear line of sight back towards the Ft Myer transmitters.
