Yes, the double bay Gray-Hoverman outperforms a ChannelMaster 4228 significantly, by roughly 3dB. Being twice the size, it would of course pick up twice the signal. 3dB, by the way, is double the signal.

If you can get the parts cheap enough to save some money or if you really need an antenna larger than ChannelMaster can supply you, then build this thing. Otherwise, you can get a ChannelMaster 4228 or 4221 (depending on what you need) with a lot less hassle and it'll serve you well.

I use a ChannelMaster 4228 to receive HD signals from 45 miles away, despite mountains (multipath) and my refusal to put it on a tower on my roof ike I should, instead putting it in my attic.

I putting in a splitter (which attenuates 3dB plus) showed me I could even do this with a 4221. Too bad I didn't know up front, a 4221 is cheaper, easier to get into the attic, and easier to reorient in the confined space of my attic.

The single-bay Gray-Hoverman is 32"x40" and performas similarly to the 36"x40" ChannelMaster 4228. But they don't do this comparison in the article. They compare the 20"x40" CM4221 to the 32"x40" single-bay Gray-Hoverman. And they compare the 36"x40" CM4228 (which is basically a double-bay 4221) to the 75"x40" Gray-Hoverman. The Gray-Hoverman picks up twice the signal in both cases, by virtue of being twice the size.]]>Apr 6th 2008 1:36PMhttp://hd.engadget.com/2008/04/06/diy-gray-hoverman-antenna-promises-better-ota-reception/http://hd.engadget.com/2008/04/06/diy-gray-hoverman-antenna-promises-better-ota-reception/Apr 6th 2008 5:29PMhttp://hd.engadget.com/2008/04/06/diy-gray-hoverman-antenna-promises-better-ota-reception/http://hd.engadget.com/2008/04/06/diy-gray-hoverman-antenna-promises-better-ota-reception/Apr 6th 2008 12:52PMhttp://hd.engadget.com/2008/04/06/diy-gray-hoverman-antenna-promises-better-ota-reception/http://hd.engadget.com/2008/04/06/diy-gray-hoverman-antenna-promises-better-ota-reception/
Perhaps if your local VHF station is also on 12, you can use a UHF antenna to receive it too.

Note that I don't use a 4228 to pick up KNTV-11, I actually find that they are on VHF to be a huge advantage. I use a Yagi to pick up KNTV-11 and use a VHF/UHF splitter reversed (in combiner mode) so that the yagi picks up KNTV-11 and my 4228 picks up the UHF signals. This is advantageous because KNTV-11's transmitter is in a different location than some of the others, and this lets me aim each antenna better.

If your channel is in VHF-Hi (7-13), you can use a much smaller yagi than you think. This is helped by the better signal propagation of VHF over UHF.]]>Apr 6th 2008 1:40PMhttp://hd.engadget.com/2008/04/06/diy-gray-hoverman-antenna-promises-better-ota-reception/http://hd.engadget.com/2008/04/06/diy-gray-hoverman-antenna-promises-better-ota-reception/

Do you have instructions on how you built yours? Material, parts list, etc. Did you use the dimensions on the sketch at the link?]]>May 30th 2008 10:13AMhttp://hd.engadget.com/2008/04/06/diy-gray-hoverman-antenna-promises-better-ota-reception/http://hd.engadget.com/2008/04/06/diy-gray-hoverman-antenna-promises-better-ota-reception/http://www.digitalhome.ca/ota/superantenna/
