Since it's supposed to have good rejection at the back, I've heard recommended to also turn the antenna around and see in which direction the signal is most rejected as you get in closer.
It has been single digit temps in NY overnight a while now. When the sun comes up in AM my solar panels put out great . We got about a foot of snow from last storm. With that antenna you can use a attnulater on HT to drop signal when get close. Same one you use on tiny SA . Just a outher fox hunting trick. 73
Thanks for pointing out the durability and small tear down size. I should fix up my old Zed-Ell special (one of the dowels split where the nail goes through it to mount it to the boom), make one of these, and compare. The quality of the null is the thing. For the usual organized hunt (as opposed to tracking down a bad guy) gain isn't actually desired, what you want is F/B ratio. Since dipoles have a pretty good null off of the end, they might be interesting to try, if you can keep the feed line from becoming an element. Maybe twin lead fed? Or a scattering of beads with a good balun at the feed point. A J-pole turned horizontal is another possibility. What I've always wanted to build is an electronically rotated antenna (using PIN diode switching on 3 or more antennas mounted in a circle) so that you can compare the rotation phase to that of the FM modulation that it imparts upon the signal to read relative bearing. I think it an issue of the old "Ham Radio" magazine that had one of these several decades back, using a CMOS analog mux in a switched capacitor filter, driven from the same counter that was switching the antennas, to extract the phase from the receiver audio. (About 60,000 RPM, or 1000 RPS, to give 1kHz modulation, so that it's comfortably in the audio pass band.) Now where did I put those PIN diodes?
Cool video Steve. Where in AZ were you when you filmed this? I went to college up in Prescott AZ and worked in Phoenix for 5 years before moving back to NY. 73, Bill KC2KNA
Fun project, that I have never done for some reason.
slacker!
These are fun to make. I made one when I was looking for an inexpensive way to work satellites. Added an extra 90* PVC piece at the end for a handle.
I've seen them with 45s at the end as well. Good tip!

Exactly!
You read my mind. I bought the stuff to do this last night 😂
I'm always one step behind greatness!
Awesome I may have to stop over an visit or have you pop in over here while you are in town. It would be a real kick getting to meet you.
Email me.

Stay warm!
Oregon is 50 degrees at the beach…. No wind yesterday
Come on you’re from Wisconsin that ain’t cold. It was -23 here this morning perfect timing. I want to build one of these.
Gotta be dramatic on camera, its the rules.
Thanks Steve, You do a great job of explaining things. Stay Awesome.

Thanks, you too!
I would suggest adding some weight to the end of the handle closest to you for better balance
That is a most excellent idea!
Nice work, very creative, tnx Man!
I had a lot of fun building it!

There is always so much to do in this hobby... just look at all my browser tabs!

This was in Benson
The directions showed a scope with an antenna pattern. How is a scope used to display an antenna pattern?
Beyond my knowledge, but I'm interested as well!
Hey TO fun video as always. Are you back here in Benson Arizona?
I'm in Benson until end of February now.
I like our style, very intuitive. Keep it coming. 73 de DO7FLY
Thanks Christian!
