Hey Mike:
Here's your rabbitears.info report (takes about 20 seconds to load). You can actually go the searches there and put in your address to nail down reception at your specific location.

Good advice above regarding amps. Looks like you have both High VHF (1) and UHF channels LOS and 1 & 2 Edge. Perhaps an RCA 751 or similar could work depending on any obstructions you might have, as your mentioned. You might want to think about a good antenna instead of the amps right now. Get up on your roof (safety first!) and find the spot which gives you the best reception.
Just my two cents worth.....
