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
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
oh oh oh oh oh:
- corner reflector
third-harmonic is still really tempting actually. if only we could get the bandwidth where we want it...
the feedpoint impedance is basically chaos at third harmonic, hah
@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.
