K6ARK 2 Element Yagi Build

I have had this antenna build on my to do list for a long time. Well the other day I finally got around to building it

I asked a friend to print the brackets as I don’t own a 3d printer.

It helps to have a metric measuring tape as the measurements are all given in millimeters.

Here you see it built (incorrectly, I swapped the driven and reflector elements)

And handheld

The SWR was below 1.5 across the entire 2 meter band. It looks like the minumum SWR point was below the bottom of the band but since the SWR was pretty good I decided not to tempt fate.

The antenna breaks down without any tools and packs down nicely.

It is a little unwieldy when collapsed but it fits nicely in a 4"x36" shipping tube

Because it’s so light, it’s very easy to rig up on a mast. This is the antenna lashed to my painters pole. I broke out all of the knots I knew, using a square lashing to attach the end of the boom to the painter’s pole. I then used a bowline knot to secure the driven end of the boom to the top of the mast. And where this line intersected with the reflector I tied a clove hitch to maintain the yagi in a vertical orientation.

This worked very well and I was able to work the 146.670 repeater from my house with just 1 watt of output power. That repeater is 10 miles away as the crow flies.

Overall I am very impressed with this design, it comes together quickly, breaks down easily and requires no soldering and minimal tools.
