Testing the Arrow 146-3BP 2M Yagi Antenna

I tested out the Arrow 2M Yagi antenna that I got a couple weeks ago, by hitting the Pottstown repeater on 2.5 watts from my yard. The repeater is about 25 to 20 miles away. I spoke to another ham who said I had some background noise but was intelligible.

To attach the antenna to the camera tripod, I made an adapter from a piece of 5/8" aluminum rod. I turned one end down to fit into the antenna boom, and then drilled and tapped a 1/4"x20 hole in the other end.

There's about 2" of rod in the antenna boom, while there's about 1/2" of engagement with the mounting screw on the tripod head. This is a temporary, light duty setup, but it's easily portable.

As a follow up, I was able to have a QSO on 2M FM simplex with a friend using this rig. Distance was about 22 - 25 miles. 5W on my end, while he was using 50W into a Kenwood 2M mobile with a tape measure Yagi on his end. (He would've lowered power but forgot how and didn't have his rig's manual handy.)

We also tried it with a Baofeng HT connected to his tape measure Yagi, but all I could hear was static when he called me, even though he was able to hear my transmissions clearly. The Japanese radios definitely have better filtering than the $30 Baofengs.
