I am 5 -6 miles away from the broadcast towers for the DFW area. I can see them clearly out my front door. I can pick up more digital channels with my rabbit ears than with the antenna on the roof, which is a Winegard Sensar II non-amplified provided by Directv. I still can't receive Fox, NBC or ABC which I would really like to receive. HELP!

I was pulling my hair out trying to get local digital channels in Philly. I'm 7 miles from the towers. I tried rooftop antennas and nothing really worked. Then I borrowed a Zenith Silver Sensor from a friend and it worked! I guess I was overloading my TiVo (HR10-250) with the rooftop stuff. Now I've got the Silver Sensor sitting on top of the TiVo in a cabinet and I get most of the locals rock solid!

Suggestions...

1. try and antenna that doesn't have tremendous gain or amplification.

2. try putting an attenuator on the line to back off the signal a bit.

Good luck.

juju - you may also be suffering from multipath, that close to the towers. That's the big problem we have here in Denver. To solve that, you have to have a very directional antenna. I don't know if that's your problem or not, but if you have hills, tall trees, or tall buildings around you, then it certainly could be.

Thank you so much! I went and got the Silver Sensor, hooked it up in my closet with the Future Smart structured wiring. And it didn't work very well, probably too much interference with the millions of wires in the closet. I took it outside and hooked it in where the Winegard gs1000 use to enter the house. I then just placed it in the garage and I get EVERY digital channel in the DFW area, even ABC which broadcasts on a VHF channel. AWESOME!!!!
