A comparison to any other antenna would be useful. A comparison to a 50 ohm resistor with a similar counterpoise wire would be even more useful as a baseline measurement. If anyone wants to lend me their AX1 I will do that.

I've been impressed by how well my little AX-1 whip antenna performs on 20 meters. Here's a photo of the rig: https://gruner.com/k4rhg/andover_ma.png and the propagation map: https://gruner.com/k4rhg/wspr_2watts_sep16_2022.png A friend, Derek Rowell (AK1WI), gave me a two-watt WSPR kit he had designed -- easy and fun to build. I connected the unit to the AX-1 sitting in a window sill facing west and strung the out-of-the-box counterpoise over a lamp shade and bed headboard. No idea what the SWR is, but it must be pretty good. I immediately began receiving propagation reports and within 24 hours had reports from 240 unique stations. The farthest was VK5ARG (17,276 km) with a SNR of -21. Even though the window faced the west, propagation into Europe was strong with SV9KI (7,800 km) reporting -26 SNR. The propagation report is from http://wspr.rocks/ <http://wspr.rocks/> I've found that WSPR is a great way to evaluate antennas. The AX-1 seems to be performing very well. 73, Ron Gruner K4RHG -- ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to ab7e...@gmail.com
