Flagpole

I added some sections to the flag pole to reach 37 feet, and I increased elements on the home-made yagi from 2 elements to 4 elements. Upon adding elements, I needed to stretch the driven element a couple millimeters longer to tune it. In testing, I’m seeing about -100 RSSI listening to W3GMS on a Quansheng. It was about -105 RSSI when mounted lower and only 2 elements.

Tilt-up Flag Pole

I figured out to do a tilt-up flag pole against the house reaching 25 feet into the air. It sits on a stake in the garden, and is secured to the house with paracord in an eyelet and hook screwed into the side of the roof.

2-Element Yagi

I built a new 2-element yagi using an online calculator It tuned OK with the banana-clip adapter directly connected to the driven element. I first tuned the dipole, and then added the reflector element. As predicted, it shifted the tuning slightly, so I trimmed the driven element to retune. The nice thing is that the spacings and sizes of the original elements don’t change as you add more director elements, so I calculated it with 2 or 3 directors, but put none in for the first iteration. I can add more elements later.

I gave it a try to reach 985 with the TYT TH-9800 running 50W. It was scratchy, but copy-able. I have more flag pole sections ordered to make it a little higher.
