In this video I make a 2 meter 5 element Yagi Antenna that weighs just 21oz. In a later video I will show how well it works on FM and SSB.
Dimensions,
reflector - 20 1/8" x 2 1/4" in from end of boom
driven - 19 5/16" x 2 11 3/16" from reflector - insulated from boom use nylon washers and all thread
dir. 1 - 18 3/16" x 2 17 3/16 from reflector
dir. 2 - 17 15/16" x 2 37 5/8" from reflector
dir. 3 - 17 11/16" x 2 58" from reflector
Boom is 1/2" aluminum tubing 58.5" long

Got to love the directional antenna. I've busted so many pile-ups on 10, 15, and 20 meters with the Mosley. Making a 2 meter yagi looks like a fun project. Maybe even do some fox hunting, or add a 73cm component and do satellite work. Man, you insoired me to get creative. Maybe I'll do a tutorial on antenna modeling software.
@KK6USYHamRadioAdventures
@KK6USYHamRadioAdventures 3 года назад
Chris I have a ta33 and even at 10' testing it was amazing. I have never had a pileup on 2m until using this antenna on a POTA. This is a fun antenna to make use square tubing to mak it easier, thanks for the comment and for taking the time to watch!

Yours and Adams are way slicker! You guys are keeping my local harware store in business. Keep making these videos; they keep me inspired. Good to see you 73 de Bill. ps - what pole is that, and how far up is it?

So on 146.520 did you spin yagi around to vertical? Also what was best distance on fm vertical and ssb horizontal? Thanks!!!
@KK6USYHamRadioAdventures
@KK6USYHamRadioAdventures 3 года назад
Mimi Heaven , Yes For FM vertical and SSB horizontal, the antenna covers both parts of the band with swr at 147.0 1.0:1 to 1.3:1 at 144.0. The day I test I had contacts up to 100 miles with the antenna at about 10' or less most of the time. I didn't have a lot of time I had already finished a POTA that morning and needed to packed up and head home. I was also at 6000' elevation and that doesn't hurt any Lol. I will have a second video out soon with a better look at how it was constructed and materials used. Thanks for the comment and for watching.

Did you manage to reuse the arrows for anything? Perhaps you can mount them into a tube so the outside conducts. Is there an explanation as to why the 1st director is so close to the driven element? Thanks

dose one need to put this on an SWR meter or dose one just build it and it will be good enough? The reason I ask is I don't have an SWR meter and would like very much to build one
@KK6USYHamRadioAdventures
@KK6USYHamRadioAdventures 3 года назад
Sam if you build it to the dimensions I posted below and use the same materials it should be very close I used the link I posted and didn't change anything and it was good. It is always best to check the swr though maybe get the best swr meter you can afford you will always use it later. 73
