There's a few things everyone should know about TV antenna range.
- Unfortunately, there isn't a standardized test to evaluate antenna range.
- No one goes to jail for falsely stating antenna range.
- Usable TV signals do not travel 150 miles.
- The terrain in the signal path a big factor that will determine antenna range.
- In the antenna business the more you exaggerate (lie) about antenna range the more antennas you sell.
Mounted outdoors the average real range of the EZ HD is 50 miles. A little further if the line of sight to the TV transmitters is very good or a little less if the line of sight is poor. Attic mounted in a suitable attic > you can expect reliable reception from 30 to 40 miles.
