Looks like a "meander line" antenna. Not uncommon to see an entire antenna done this way on 433MHz and up radio modules. I swear, every 2.4GHz transceiver module must use the meander line antenna. --

N2VIP, not sure if you have read the other comments (Jeff KN8A & James M0JMX) in this thread. I didn't claim to know either way (yes/no) if any ARRL (or any other US predecessor) publication covered

"N2VIP Which ARRL era publication would have published this?" You said hams were discussing this antenna design for three decades, "a very old design HF antenna (post WW2 apparently from the

Sam The antenna does work. I struggled with keeping it all in line at times. I tried a couple of ideas with a few different prototypes in my practical experiments I may have it somewhere still John

Jeff K8NA, It took about a year of design, several jigs and a two & three person effort to get the assembly working as the elements needed stringing with wires that always sagged until we came up with

Thanks James M0JMX, the original article (1950s) is what I used to model practical antennas that can be made from now on. There were couple of versions, possibly a technical paper as well but I didnt

Not enough coffee yet...

It sure sounds like this: https://www.n5ese.com/notebk_ant.htm The date of the article is probably around 2003, given the comment here: https://www.n5ese.com/notebk_ant_comment.htm In the 70's and

It appears to be mentioned in this amusing radio club newsletter from 1963: https://rsars.files.wordpress.com/2013/10/mercury-4.pdf Apparently a version of it enabling an operator in Bradford to cause

Very interesting. I have a small space for the antennas and up to now I never had something for 80m. How can we understand if we can build it with the equipment we have? Pietro I2OIM

Correction: NEDA = non-inductive end loaded dipole antenna. That's pretty much the theory of the system I can figure out. I wrote GNU octave code to produce geometry and then did antenna analysis on

No no, not a vertical. Horizontal orientation models only. There wasn't a name for this antenna in a 1958 article by M. J. Heavyside, Ph.D (G2QM) he published theory and a report of his work. So,

Apparently it's a type of vertical (1' x 1' x 12'). Is there a reason to think this design is not included in the ARRL publications of the era Ken, N2VIP

What general type of antenna is it? Joe n1khb Sent from the all new AOL app for Android

Can you ship a picture or drawing. Would help to visualize. Also forwarded to another group of smarter hams. W4DBL Doug Lynch President Aries International, LLC D: +1-321-415-2191 M:

Hi, FT-817 QRP users, I am one of the developers of a modern incarnation of a very old design HF antenna (post WW2 apparently from the documentation I have) that was rediscovered/tested by other hams

Complete with both filters on board, already sold

Sorry it already sold

Saad did you sell this?? More info please too alpinewarren@... if not 73!? AB6YA

Those particular driver FET's ae easy to replace. They are surface-mount, but they are SOT-89 cases. Just use some solder wick and the edge of an X-Acto knife to pry the part loose while heating the
