new build technique: pinch the centers of the dipoles a bunch of times with a wire cutter to rough them up and make them fit badly into the mounting holes, then pound them in with a small hammer. no centerpunch or setscrews required!

this one is gonna be a Lot cleaner in overall assembly than our cane lol

really makes us wanna redo our cane, but we're out of boom material now. :(

maybe we can find some round rod to use instead, that would be really pretty

ooh ooh and we could sand the rod square in places to make it fit our handle attachment :blobcat:

now we're being a bit silly but hear us out:
- replace square steel boom with round ???? one (steel? aluminum? fiberglass?? wdfk)
- replace steel directors with beautiful shiney brass
- redo feedpoint and gamma clamp
- as tempting as it is to go third-harmonic, that would be kind of silly


third-harmonic is still really tempting actually. if only we could get the bandwidth where we want it...

going third-harmonic would give us way better directionality in the vertical axis and improve gain too, AND make it look even cooler by making the dipoles hilariously long. BUT it kind of wrecks the bandwidth a lot (that 400 MHz we have now would be hard to let go of) and also it seems really hard to get the front:back ratio to behave itself??

the feedpoint impedance is basically chaos at third harmonic, hah

@diodelass i've had excellent luck running 3rd harmonic on a 40m vertical, the impedance isn't chaotic at all, but will always be higher than what you want it to be. probably entirely inappropriate for VHF and up.

@mngrif for a high-element-count yagi-uda, isn't impedance being too high the least of your worries? for yudas, it's usually too low, and we have gamma matches and stuff to keep the SWR under control.

our simulation applet thinger just shows a pretty bumpy landscape for reactance in the frequency domain for third-harmonic antennas, and the bandwidth is like a fifth of what it is for a fundamental-mode antenna.
