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:

Newbie Builder

Hello, I'm relatively new to antenna building however I'm learning by trial and error..i have built 3 Hoverman antennas and all work great. My first was a 2 bay with aluminum foil reflector that works great in the attic 25 feet above ground , my second is a single Hover w hardware cloth reflector mounted near chimney 30 feet up outside..that one works great, I'm picking up Daystar channel which is a 2 edge 40 miles away..and my 3rd is another single that is a "mobile" antenna I take when I visit my brother in Syracuse Ny..I tried various sized bow tie builds and suffered through some commercial yaggis that just were horrible..I believe the Hovers are the best yet I've tried..thanks I enjoy reading on your site here..

Hello! Long time lurker. First time poster.

I just wanted to pop in and thank all the fine folks here for all your help.
With the children more and more into their laptops, iPhones, and iPads, I've finally gotten around to cutting cable and going with an OTA set up supplemented with occasional online streaming. I've read all the helpful info you fine folks have shared and completed my first single bay GH antenna.
I average about 14 miles from the local transmitters. All are basically along the same path. My initial tests were promising prior to building the GH for all local channels with the exception of a low VHF channel (CH5). I finally had CH5 licked with a homemade single channel dipole I made and planned to use the dipole with a VHF/UHF signal combiner. With the channel 5 issue solved, I made up the GH6 using honeycomb panels that ended up making the antenna a large flat box. Active elements on the front side, the NARODs on the back side. I modified the top and bottom NAROD's from the straight rods to the top hat style. I used 9 gauge dead soft aluminum wire and a quality balun. Once finished, I placed it in the attic and hooked it up to one TV. I was amazed at the clarity and especially the signal strengths. 41 channels received with 24 that I kept. Each channel was at 95% or more and the problematic CH5 was coming in at 80-85% signal strength, the same as the my dipole I made. I ended up leaving the dipole off as it wasn't needed. The GH now feeds 5 TVs with only minor grumbles from the kids who miss their favorite cable channel.

Thanks again! Ya'll have a fine group here!
