Continuing from here…
I put up a dipole this time, and while I did receive marginally more stuff than before (only in the 2m and 70cm bands), there was also a lot of noise. The length of each leg of the dipole was calculated like this, with the velocity factors estimated for the copper wire and insulation.
(299792458 / 52_000_000 * 0.95 * 0.95) / 4
I did get the copper pipe for making a sleeve balun. Would that further improve things? :3c
Well, I tried building my own ¼-wavelength monopole with the metal railing and everything it's attached to as the ground plane, but it didn't work very well. :(
I'm targeting 6-meter with this, but I thought it'd make sense to use the middle of the band (52 MHz) as the target, so I did (C / 5200000000) / 4
to get the length of 1.44 meters.
What did I do wrong? :( #HamRadio #AmateurRadio
Still not having much luck here. I shortened the dipole to try to cover the 2m band and did get more stuff coming in, but it was all noise. :(
I can't realistically make the ladder line fully vertical due to space constraints. Maybe I just need to build a monopole instead? The balcony railing might make a good ground plane.
Or do folks think an external antenna tuner would be worthwhile here?
Simple cable rim brakes saving my ass as always (at least until the front disc caliper is fixed on my other bike). :P
