Re: FS Yaesu ft-817nd. Located in Toledo, Ohio. Soon Moving to assisted living location. No Radios allowd. Asking $475 plus shipping.
You know, I dread that day of moving to "assisted" living, too. Perhaps you're allowed a computer and can check into "Hamsphere" or "CWHotline" to stay active in the hobby. I'm sure a local ham would

Re: results of new US antenna design - advice sought
Guys, It seems that you have missed exactly what this antenna is.? The cage acts like a capacity hat, adding enough impedance at the ends to bring the antenna to resonance.? I think you may also be

Re: results of new US antenna design - advice sought
I¡¯m mindful that a dummy load has a pretty good SWR. So what would be a good metric for a new antenna? Likewise, adding a tuner, in my mind, does not make an antenna better, only more compatible

W8LM, Instead of the word "new" what would you you consider acceptable? Technology is reinvented and adapted everyday. What we are developing is practical functional examples of the original

Re: results of new US antenna design - advice sought
A headline such as? "Results of new US antenna design" is somewhat disappointing when all references in this thread indicate it's a revisit of published material from 50 years ago. SWR is NOT --IS

Re: results of new US antenna design - advice sought
yes, finally ! well, almost. On a PCB meander line antenna the radiation resistance equation gets complicated due to PCB dielectric and also co-planar and planar conductive surfaces (other traces that

Re: results of new US antenna design - advice sought
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
