Half the length of your whiskers. Most people are using 7" whiskers on the coathanger units. So a 2x4 is 3.5" tall and works perfectly. To get the upper range of UHF you need slightly longer ones though. For philly market I needed 9.5" IIRC

I just built one of these - it works very well. Instead of coat hangers, I used copper clad steel welding rod. The sticks are 36" long and were $.59/ea. I needed 5 of them. Much stiffer and nicer material than a coat hanger, and cheap, too. I mocked it up on a 2x4, and tack welded the welding rods together with a MIG. Found the 75/300 ohm transformer at ACE for $3.50, so I have just under $7 into the thing.

the length between the "V" and the reflector?

that is a great desine and works great.

Has anybody made a fractal dtv antenna that uses Kock's Snowflake?

Seems like it would be made of one lenght of wire like the old uhf loop antenna.

@athlon866 For the price though a homemade one is well worth it, I didn't have to buy a single thing because I already had everything needed to make one. Don't ever throw anything away, you never know when you might need something that most people throw away.... ;) It amazes me all the things people throw away that could still be used...

@athlon866 I got one from ebay as well, $5 total for both types. I couldn't wait though and bought one from Radio Shack before my ebay one came in... For the price it works very well but I have been using a basic $10 or so store bought one for about a year now that I have mounted outside and it works a lot better. I just hung it from a nail outside and it actually gets more channels than the one I built.

@athlon866

thanks!

@em0rox I had to get it from ebay. I can't see them at dollar store, and the radio shack is too far away from where I live. I have already made a successful one. It works awesome!
