It should be noted that I have an antenna on the roof pointed East towards Philly. I use the Sangean tuner which has excellent sensitivity.
Then you have a
big advantage over the typical listener (with a line cord antenna or wire hanging off the back of the radio) which breaks down roughly as follows:
1) Moving antenna from 4 feet AGL to a roof top at 30 ft AGL -- about 15 dB improvement
2) Using a directional gain antenna cut for the FM band, rather than an untuned piece of wire -- at least 6 dB additional improvement
3) Mounting the antenna outside the house, where the signals aren't encumbered by foil-backed insulation in the exterior walls, house wiring, pipes, HVAC ductwork, other nearby metallic objects, drywall, etc. -- let's call that 5 dB
Add it up, and that's about 26 dB more "raw signal" into the receiver; equivalent to a power multiplication of 400. And, on the rooftop, your antenna is further away from computers and other household appliances that generate noise. Plus, with a directional antenna, you have the ability to reject interference from undesired stations, not to mention the excellent performance of the Sangean tuner.
I'm using an attic antenna and getting good results with the Accurian HD receiver in northern Chester County -- but with the supplied Rat-Shack-Tail antenna, indoor digital reception is very poor. In this kind of terrain, anyone who lives outside the 70 dBu contour of a station needs to keep HD coverage limitations in mind. It's not a cure-all for weak or noisy RF signals.
By the way, I'm just curious to know if you can receive WDAS-FM in digital with WIOV so close, or B101 with 101.3 "The Rose" not that far away.
