Looking for a multi band #HF vertical #antenna (I’m space constrained). Any recommendations?

Should be available in or for shipping to Australia. 😬

@N4JAW Looks like more #HamRadio fun ahead for you! Enjoy having (even) more antenna choices in the field! #Antenna
Why yes that is 9 20' cb antennas. I'm getting ready to finish a project I started a few years ago. It'll be a 9 circle array for directional reception on 160/80/40. #hamradio #antenna
To those who responded to my earlier request for 6m antennas, thank you! I've narrowed it down a bit to a 6m squalo-type, as pictured. However, the site https://www.kk5jy.net/6m-halo/ doesn't have exact dimensions. Not a huge deal, but I need two dimensions specifically: The gap between the wires looks to be about 10cm or so, and there is no detail on the matching system at the feedpoint. He says "a loop to add some inductance" but that's about it! #6m #antenna #HamRadio I have emailed, no joy.

I tried to make a 5/8 wave length ground plane antenna for Meshtastic, I had one N-connector for that one left.

82mm for the radials, 205mm (start with 1 cm more and cut later) for the straight radiator and 2 windings around a pencil as a matching coil (the wire was 270mm in total I think).

The NanoVNA showed a SWR about 1.07 at 868.5 MHz and a short walked confirmed a good signal:

Distance: 931m
SNR: 5.50 dB
RSSI: -86 dBm

Later I will go further.

Very thankful after days of high winds to get a fairly low wind day in time for the Indy 500 so I can watch the race with my digital antenna instead of having to deal with the Fox Sports app I hate worse than anything on Earth.

Quick & Dirty Sunday DIY Project. L-Match for 27MHz.
Toroid : T80-6 with 23 turns (~2.62mH)
Capacitor : 2pF - 30pF
Network Type : L-Match

Wait for better weather to test. But with 4.4k resistor I can match a VSWR 1:1.1

Free stainless steel garbage cans around here. I am so tempted to make this into a dipole antenna, so I can call it a "trash can antenna".

(If you have a couple of spare Cybertrucks, we could do the same thing, but on lower bands).

Wow! Finished building my first 868 MHz ground plane antenna for Meshtastic!

Still needs SWR measuring with a VNA and maybe shortening a bit, which will be my first time doing that, too.

For a test it already got too late but I will keep you updated about the results. Also I would like to try different antenna designs, it's quite fun!

@finn 👍

Wann kommt die #Amateurfunk-Lizenz? 😀

@ls Oh ha... E-Technik ist schon so lange her, ob ich das noch gebacken bekomme?
@finn Klar... es gibt jetzt auch eine neue Einstiegsklasse, und es gibt auch Upgrade-Prüfungen falls man später eine höhere Lizenz anstrebt. Die Fragenkataloge gibt es online, falls Du Dir einen Überblick verschaffen willst. Alle Lizenzklassen kann man auch ohne Studium schaffen.
@finn Es gibt jetzt auch eine neue Lernplattform: https://50ohm.de/
