Yep, the Make video is the same one as the Engadget and Vimeo one... very tidy build. :)

I'd be interested to see what mclapp or any of the other bowtie antenna gurus has to say about that new video build.

Anyone else notice the guy in the Make video calls the premade 4-bay bow-tie a Hoverman. That's not right, is it?

A suggestion about those new videos...

If you can leave a comment at those video sites please say that he's incorrect about the term "Hoverman" and also put in a link to our site's Gray Hoverman intro:

http://www.digitalhome.ca/forum/showthread.php?t=81982

I find it irritating that on the Engadget site's description of the Vimeo video they have a hot link with the term "We've seen a few complicated DIY antenna projects" that directs to the Gray Hoverman. The GH is easier to build! :rolleyes:

Maybe we'll clear some things up somehow.

In the pdf on how to build that antenna he mentions that the design was invented by Doyt Hoverman in the 1960's.
I don't know maybe he did come up with that design as well.
All I could find is this 1964 patent which is very similar to the G-H devoloped on this site
http://www.google.com/patents/pdf/R_HOVERMAN.pdf?id=TOtiAAAAEBAJ&output=pdf&sig=ACfU3U3znnG25OEwUsxEIgaNuuTY_9Hqmg

I find it funny that in the beginning of the video he shows a factory made antenna then goes on to show you how to build one that has wayyyy different dimensions.

I've never built one of those to field test but the computer models show them to be very bad in the lower UHF channels. Many people have had success with them though.

Ya, the doc you found is for one of the two original Doyt Hoverman patents that Autofils used to design the Gray Hoverman.

I've never heard anyone refer to a Hoverman patent on Bowtie Reflector antennas. :)

Has anyone compiled a step-by-step how-to, with a complete bill of best materials?

Also, would the double design work side by side, rather than vertically stacked? It might be easier to put in the attic side by side.

I'm confused then, I would agree with Engadget that an antenna like this:
http://www.digitalhome.ca/forum/showpost.php?p=767687&postcount=8
Is a lot more complicated than a piece of wood, some coat hangers and screws.
However, I would also expect the GH antenna to operate quite a lot better, especially considering it's size!

I tip my hat to mclapp, perhaps the most knowledgeable and experienced 4-bay bowtie reflector builder on the web, who says that building a GH is easier.

When you think about it, if you are building a GH for attic mounting you only have to bend 2 long pieces of stripped solid wire in a specific fashion, attach them to a piece of wood, and then put aluminum foil on a piece of either plywood, strong cardboard, or styrofoam to attach as the reflector.

For outdoor use the need for solid, weather-proof materials makes for a much more involved build.

My GH10 is attached to south wall of my house.
I constructed a frame using 3/4" cedar nail strips from Home Depot.
It's surprisingly stiff and should weather well. Cheap (under $30 for all parts)
and looks good according to my wife.

The antenna is sheltered and receives little wind load.
If it was attached to a rotor or more exposed I'd probably construct it
out of more stronger and durable materials.

For better performance, especially during wet weather, you want the driven elements only touching plastic (and as little on that as possible too) instead of wood. The reflector parts on cedar wood are fine.
It sounds like on your build you could do that fairly easily with some quality composite decking (scrap or samples) strips, cut to say 3/4 inch by 3/4 inch by the distance you need to space out the driven elements.

I've wanted to try OTA for a while now, and I finally decided to make my own antenna.
Just a tiny fractal deal like this one:
http://www.youtube.com/watch?v=mNRZEM9wJz0&feature=related

I couldn't believe it.
City, CTV, Global, CBC, SRC, Omni iI and II, all in HD - and a bunch of others in analog.

I'm thrilled with the results, and I'll be building a Gray-Hoverman this summer.
Also, I'll be telling Rogers to cram it.

Thanks Digital Home!

Oh, I'm at Victoria Park between Danforth and St. Clair. Line of sight to the CN Tower.

I analyzed UHF 4-Bay (No Reflector) versions posted by babblin5 and MakeTV
versus CM-4221 & mclapp M4 (if remove Reflectors):
http://imageevent.com/holl_ands/4bay
UTube antennas are too small, esp. for reduced UHF Band...and have SWR problems...
Spacing between bowties needs to be much larger than 5-3/4 inches and whiskers
could be longer....

I also posted plans/analysis for 8-10+ dBi gain Zig-Zag antennas for HiVHF band that
I think are perhaps easier to build than the typical LPDA shown in post #1:

I'm very new to OTA... I followed this guide today:

http://www.metacafe.com/watch/762088/coat_hanger_hdtv_antenna_better_than_store_bought_amazing/

I'm in Fonthill so I'm at one of the highest elevations in the peninsula. I wasn't really sure what to expect.

Just sitting in my living room plugged into my HDHomeRun... I was able to scan for 12 digital channels. Got NBC, ABC, CBS, CTV perfectly in HD. No FOX but I hear that's quirky & directional.

I must say I'm blown away. I'm confident enough now that I cancelled my Cogeco this evening. Now I just need to figure out if I want to invest in more than my DIY antenna to get even more programming. Something in the attic should be able to pull much more than this!
