First time post, but have done a lot of reading/research before posting. I have learned a lot from this site over the last few weeks as I have ventured into the OTA world.
Issue: I live about 2-2.5 miles from three transmitter towers (ABC, CBS, NBC) and approximately 20 miles from another tower with Fox KPTM and CW KXVO. Without any antenna I can pick up ABC, CBS, and NBC. Same with an indoor antenna, but can sporadically get Fox and CW. To pick up the Fox and CW stations, I installed the Winegard Free Vision antenna where my DirecTV dish was mounted on the roof. Now I can receive Fox and CW, but ABC, CBS, and NBC sporadically drop out. The other PBS stations seems to come in just fine with no problems.
To help eliminate the overload from the close towers I put in place a 4-way splitter with 7db loss and that seemed to help. However when it has been raining the reception will still drop out on these close proximity stations. I even put in another 2-way splitter, but still am getting sporadic signal drop out. But I am able to get Fox and CW without any problems.
I also ran the FMFool report and found a close transmitter less than half a mile away. I picked up an FM trap for a few bucks from Radio Shack and installed that just in case, but haven't really noticed any change in reception.
I did place an order for an adjustable attenuator, but wanted to see if there was anything else I should try.
TVFool Report:

Data from FMFool:
KIOS = 0.4 miles 55 kw Rx dbm = 3.1
KEZO = 2.2 miles 95 kw Rx dbm = -3.4
Antenna is facing approximately 185 degrees (neighbor's tree in direct line to Fox at 219 degrees). Trees immediately east and north of house. Trees across the street (South) approximately 150 feet away and 75 feet high.
Antenna connected to distribution point with RG6 quad. 3-way splitter at distribution point with home-runs to TVs. Only two TV's in use at this time, but plan on hooking up the third tv soon. Longest run is no more than 75 feet.
One last thing -- I did try an RCA ANT751 directional antenna pointed toward the Fox/CW tower, but that seemed to make things even worse. Seems like the gain was too high and caused constant drop out on ABC, CBS, and NBC.
