Thanks! I made the antenna easy to change the length of for a reason. :3
Here's the 50-60 MHz graph from the original post, by the way.
Looks like the dipole likes much higher frequencies than I can really make use of with my transceiver. :P
Well, did the SWR analysis of my dipole using my NanoVNA and things aren't looking good. :(
- 6m: SWR never drops below 10.
- 2m: SWR is 2-3.
- 70cm: SWR never drops below 3.
Now I'm wondering if the stucco walls several inches from either end are causing problems, since stucco contains a fine metal mesh. Or maybe it's this 9" turn of coax near the transceiver? :/
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) / 4I 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) / 4to get the length of 1.44 meters.What did I do wrong? :( #HamRadio #AmateurRadio
I did try a G5rv shortened to the appropriate length for the shorter bands, but didn't have much luck.
Would something as simple as this be good?

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?
