I adjusted the contrast/brightness and scaled it up a bit. That should make it easier if anyone else has difficulty reading the original...

Thumbs up Big Thank You

Nothing new here, nor any questions - just a big thanks to everyone involved in posting the Gray-Hoverman design and building tips. With the change to exclusively UHF my old Radio Shack log-periodic wasn't cutting it anymore and I am not really interested in paying by the month for the same old stuff.

I went with a Gen 1 for its simplicity and double bay for the better gain. I used 1" PVC for the frame, 1" chicken wire for a split reflector, 10 Ga copper for the driven elements and 14 Ga copper for the phasing leads. CBC has the weakest signal here and I went from no signal to pegged on both strength and quality.

Now my wife wants to know if I can build an antenna that improves the programming.

Image posting website doesn't EASILY allow it....I would have to post it as a downloadable *.html or *.doc file...
BUT SURE..."only" takes a couple dozen copy/paste actions to embed it here:

I have avoided replicating G-H results found elsewhere. Much more info can be found here: [Grey-Hoverman] [Grey-Hoverman] [nikiml's Optimized Grey-Hoverman & Stealthawk]
