Coat Hanger Antenna

[timmmaaayyy2003]

I just wanted to post my experience with the "Coat Hanger Antenna" that has been seen on the internet.

The process involves creating an 8 element UHF antenna out of a board and coat hangers (as the name implies).

All I can say is, IT WORKS!!!:D

I built mine using copper wire (12 ga). Other than that, the only modification I added to it was 2 6 foot wires added at the matching transformer so it will pick up the VHF in addition to the UHF. Best of all, it didn't cost me a dime since I had all the supplies already.

I have it mounted in the attic of a one story house and my signal strength is in the low 70's to 100 YMMV.

Now if only I could get DTV to add all the sub channels to my AM21.:rolleyes:

You say you added 2 6 foot wires at the transformer for VHF. Did you put one section of 6 foot wire under each screw? Did you pont the wires up like a "V" with this 6 foot addition?
Thanks in advance

This video is just showing how to make a DIY UHF bow-tie panel antenna. But such antennas are already very cheap; mine cost less than $20, and is out-door worthy and came with a mount for a pole.

Still, it's always interesting and fun to be able to make something useful yourself.

Does aluminum foil still work?:lol:

That's exactly how I did it. The one VHF station in my area is now at 100%.

Ah, but with mine I saved $20 and in our current situation....

Hey, $20 is $20:D

Awesome, timmmaaayyy2003!

To me, this isn't a project about $$ (ok $20 is $20), but about having fun building something that is simple and works.

Congrats!

Do you have a picture to share?

Here you go.

nice! Its always fun to build things.

[Tom Robertson]

Again, awesome job!

Thanks for the picture.

timmmaaayyy2003 looks good.

One question though, how far are you from the your local stations transmitters ?

[dodge boy]

Here you go.

Pretty Slick....
How far are you from the stations?

[smiddy]

Nice design. I have put together similar antenna in the past.

By gosh that looks a lot like my CM4228 after I removed the directional screen. Don't have the VHF rods on it however. Nice job.

The top and bottom X or (where the wires cross) Should they be touching or not if I am using Non coated 10gauge wire?

They should not touch. Even if you're using insulated wire you should still try to keep the two wires apart by a 1/4 inch or so where they cross. Have a look at this picture and you can see how Channel Master keeps the wires apart: http://www.solidsignal.com/prod_display.asp?PROD=SCM4221A&xzoom=Large#xview

Looks like a CM4221 with the reflector screen removed: a 4-bay bowtie antenna.

I love RF experiments!

This is basically a 4 bay bow-tie ....performance could be improved significantly with a reflector screen behind the bow ties. I like the modification adding a VHF dipole at the feed point. It does introduce matching issues and will modify the bow tie antenna pattern somewhat, but the key is:

1. It's cheap
2. It's fun
3. It worked!!!

Congrats on your efforts and thanks for posting your little RF experiment.

Your real last name doesn't happen to be Popeil by some chance? :D:lol:

Looks similar (not simular) to several experimental home-brew antennae I fabricated as a kid back in the day. There is very little new under the Sun, just variations on a theme, modifications and improvements.

I once made a bathroom phone with coathanger wire, and a tv remote out of a Prince Albert tobacco can, back before there were tv remotes.

The greatest 'discovery' for youse guys is that you don't always have to get your stuff ready-made at RS or BB.
