How do you prevent "Ghosting"?

Point the antenna away from obstructions, possibly.

Go to your local Rat Shack and find a signal attenuator. Its a little device with a potentiometer that goes inline between the antenna and the TV, and you can tune the knob to get rid of the ghosting...

Theoretical question...
...is ghosting the TV equivalent of multipath, i.e. reflected signals from the same transmitter traveling different pathways at slightly different speeds and partially phasing one another at your reception point?

I once bought one there that was actually called a "ghost eliminator". It didn't totally eliminate them in a tough reception area, but it helped.
I don't know if they still market the attenuator with that name, that was over 20 years ago.

Essentially, yes.

Re: Theoretical question...
Radioshack seemed to have realy cut back on there comunacation stuff, seems like they are starting to sell more and more satilite stuff then anything else. But I will check into that stuff. Thanks for the help, realy the most Ghosting I get is through the weather segment of the news, does there "blue" wall have any effect on that?

Yeah, anybody go into Radioshack lately looking for RCA cables??? They don't have them anymore!! WTF??

For what it's worth, most tv stations would be delighted to shut down their transmitters. 80% of their viewers are fed via cable or satellite which are in turn fed by fiber feeds direct from the stations. There was at one time a technology that rode in the vertical blanking interval which would allow equipped tv sets to electronically eliminate ghosts, but there was little or no interest.....just get cable.

Yeah but cable isnt as clear as regular tv antenna a lot of the time and also cable takes the fun out of dx'n

Nah, the VIR signal was a colour reference that was supposed to be more stable than just those eight and a half cycles of burst on the front porch.<P ID="signature">______________
