N6LF says โ€œ60 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. โ€œ

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!" ๐Ÿ˜†

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 , 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 ๐Ÿ“ก๐Ÿ‘Œ๐Ÿป

Itโ€™s not uncommon to do this, but itโ€™s the first time Iโ€™ve ever seen one, real life ๐Ÿ˜ƒ

While visiting sites like this, itโ€™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.

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.

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 is that it shows you people you've /#muted in all sorts of places; when your them, in , results, in etc: codeberg.org/calckey/calckey/i

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

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

All of this work is .

I did a little to my to add external so I can pick up my neighbor's 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 reception or made it worse ๐Ÿคž

Itโ€™s not omni vs directional.

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