Antennas / 82-43 for 4:1 baluns
Last post by N6TDG - January 04, 2024, 07:07:59 PM
Hello All, 

New to this forum.  The name is Jeffrey and I am from the Gold Country of Northern California in the Sierra Nevada Foothills. 

My question regards making a 4:1 balun using the 82-43's for a say 20w set up.  I would be using this to construct Rybakov style antennas for portable operations.

Would one or two 82-43's be needed to handle the watts going through using say 22g wire or maybe even something lighter like 26 or 28g wire.

I suppose I am asking what are the parameters for this sort of mini balun/unun for slightly above QRP work?

Thanks in advance.

Thank you Gil! the manual is huge help.

Would you know of any source to get the Speaker, like the one in your video? I'd like to find the whip antenna that goes with this. Or any other accessories? I really dig that speaker.

Thank you for everything you do, and I really enjoy watching your videos.

Merry Christmas!

Here in the USA we have been experiencing significant delays in banking transfers ESPECIALLY PAYROLL DEPOSITS. With the multi-year impacts of job killing COVID restrictions, inflation/weakened buying power and more, this is very significant damage to many Americans' home budgets. 

This is a key reason to keep some cash in locally useful currency, a source of safe drinking water, and food on the shelf with a way to prepare it.. If you have a bug-out location in mind, ensure that you have fuel to get there at all times.  Sitting in a potentially hostile long gas line is a bad plan.

This video shows how to make a antenna for VHF with duct tape. A very good idea for a backpack.


Enjoy.

I just got my irish Ham license and am travelling to France next week, Ile de Re to be exact. I was wondering are there any repeaters on the Island or should I just connect to the one in La Rochelle?

Merci,

Paul

Check with your license to see if you are able to transmit with a reciprocal license in France. Some countries want you to register with them in case of "problems" with having a non licenced amateur (in theory) operating in their country.

Oh! I had never thought of using leader wire, and did not even know that it came in a copper/copper wash. Thanks for showing up how you do yours.

Antennas / End Fed Trolling Wire Antenna
Last post by L1berVir - August 21, 2023, 11:14:28 AM
Here's an end fed antenna with a 1:9 unun I made. I put about 50 yards of 30 lb test copper trolling wire on a chalk line reel. You can use it as either a random wire with a tuner or just measure out the various bands and put a knot in the wire to mark where its resonant at, depending on if there's enough trees or whatever around, if you have enough cordage, etc.

I typically use about 30 foot of rg-316 when I'm running portable and I have a string of ferrites on one end of the cable near the radio so the coax pulls double duty as the counterpoise though you can obviously use a dedicated one if you want.

I'm pretty sure this antenna was NVISING on 40 (blue) given how relatively close the FT8 receptions were on pskreporter.

Anyway if anyone's been looking for an antenna that's easy to set up and take down for portable ops, here ya go.
