N6LF says “60 years ago Tom Erdmann, W7DND(SK), told me that if I had $100, I should spend the first $90 on the antenna, the next $9 for the receiver and the final $1 on the transmitter. Of course prices have gone up bit but those proportions are still sound advice. I can honestly say I have a lot more time and effort invested in my antennas than in station equipment. “

My ham (amateur) radio "antenna farm" when I was a teenager. The horizontal one was called a tri-bander (10, 15, 20 meter bands).

The tall vertical was a Shakespeare Big Stick for 11 meter CB band but could be used for 10m ham band.

I also had wire antennas for 40 & 80 meters.

My parents didn't mind the crap all over the house. They thought it looked cool and knew it mostly kept me out of trouble.

Neighbors complained of TV interference. "Not true!" 😆

A dipole cut for the center of the 630 meter band (475.5 KHz) is
982 feet 2 inches for the total length or 299.99 meters.

This for me is the holy grail.

Came across this beautiful microwave link station in #norway, a site which operates in a very special way: the signal is aimed towards a reflector in the mountains and from there it is bounced towards its destination 📡👌🏻

It’s not uncommon to do this, but it’s the first time I’ve ever seen one, real life 😃

While visiting sites like this, it’s always a good idea to look at the installation - in this case the waveguide feeds, the dimensions of which reveal the operating frequency area, likely between 8-12GHz.

@Stormgren Hey, that's pretty neat. Do you know any machinists (or are you one)? Could probably whip up a small adapter with the correct threads on each end.

#introduction

Hey everyone here is my introduction.

I am a 43 yr old Canadian guy who is a machnist/welder/fabricator by trade.

I am interested in all things technology and have been a licensed ham since 2018.

I am a fairly open book so if you want to know something just ask.

there was a time when I hit every #thriftstore in the area and bought anything with #antennas on it to #hack. 😂 #hamradio #hsmmmesh

I'm starting to get the antenna itch again, and looking at the Chameleon Tactical Delta Loop. It looks like a great option for quick deployment and recovery, and the majority of reviews are quite positive. But $$$.

The biggest problem with #Calckey is that it shows you people you've #blocked/#muted in all sorts of places; when your #followers #boost them, in #antennas, #search results, in #lists etc: https://codeberg.org/calckey/calckey/issues/9995#issuecomment-952968

You basically can't get away from abusive users when you use Calckey

Draft visualization of the electric field of the shortened #HF #antennas that @OpenResearchIns is working on.

Looks good in simulation so far. Prototypes had very good #SWR. Next, we'll be moving into the phase of building more examples and getting them on the air for some practical #hamradio testing.

All of this work is #opensource.

I did a little #casemod to my #beeLink #ryzen #miniPC to add external #antennas so I can pick up my neighbor's #xfinitywifi #hotspot better and I think I did a pretty good job! The clearance for the m.2 slot is pretty tight, but other than that I think it turned out pretty good.

Now to see if I improved the #wifi reception or made it worse 🤞

Excited, my next big #hamradio project is testing out a cool project that @smitty is developing for #satellite #antennas.

It’s not omni vs directional.

All antennas are directional, some are just more focused than others.

Please, please, show examples how to use #antennas !

IMO this is the least documented feature of calckey.
