Advertisements It helps to know WHAT stations to expect and WHERE they transmit from, before you install! The FCC offers this basic calculator: DTV Reception Maps But this site returns a VERY useful MAPS and more info! DTV Gov Maps DTV Gov Maps gives you the digital TV tower signal data and maps you need to cut the cord and switch to an over-the-air TV antenna. It helps to know WHAT STATIONS to expect, (Signal Strength wise) at your location before you install! Simply enter your ZIP CODE and instantly see: Callsign / Network / Location/ Channel/ Miles Away/ Direction/ Signal (quality) Note: The results are only estimates and every home or installation is unique in terms of its terrain, obstacles, AND INSTALLATION. These details WILL impact reception and the levels shown. I see that my 'map' is a bit dated with just 26 stations listed and lacks some of the newest stations and transmitters. But in 'the city' most transmitters are clustered on the highest peaks or building tops so the general information remains the same! Only 1 lone station is also listed at 57 miles away and will be 'off the side' of my antenna at about 45 degrees; so IF I see it at all, it's a "gift". Wish Gov Maps offered more info about the test antenna setup used to create the charts? Also sad to see they recommend a 'amplified indoor antenna' for me that looks like a black hot water bottle... yikes. I wouldn't install that antenna in my dogs house. Pure junk antennas with coax so thin that the diameter is slightly larger than boot laces. SOGLAD *I tried to find these sites listed in other posts on 'tivocommunity', but had no luck. IF these are repeats of posts ~ I do apologize.
