Can anyone recommend a source for determining over the air TV signal strength in my neighborhood?

Here

@ARE_you_kidding_me beat me to it. Also you can check the TV stations website for a reception map.

Thanks, guys! I appreciate your patience and help. This looks to be just the ticket, and I’ll look up the station’s site as well.

Another option for the US is Antennaweb.org .

They give a better map than the FCC tool, showing directions to the transmitters without having to click one-by-one.

Like @Call_Me_Jay , I use AntennaWeb .

Thanks again for the advice guys, but unfortunately, thanks to the freeway and the new noise-lessening wall in my neighborhood, no antenna is going to work here for any of the over the air stations I want. Ah well, so it goes. :-(

@canidmajor You can get one of the newer flat antennas (Mohu Leaf) with an amplifier for about $50. Give it a try before you give up.
If it does not work in your application pass it on to someone else.

Thanks, @LuckyGuy, but that was the exact one I tried, no Joy. :-(
That’s OK, more and more stations are starting to look into streaming, I’ll get there eventually!
