vu2tumA very well written article on #Moxon #multiband #HF #antenna by S21FIA

Brought wife to Target to pick up a prescription, etc., & I gave her a #HamRadio request for her shopping list. She picked me up 2 hula hoops!
I’m excited by the prospect of this much wider separation eating up more element length with less #Reactance of either sort. I’ve a gut feeling this will improve its overall behavior.
Also interested in testing sawtooth pattern vs square pattern. Really got to figure out how to get #MMANA going again.

I've played with the model in #MMANA. I like how easy it can be tuned (the length of vertical wires does not change real part of Z greatly but reactance.). But elevation is about 60°. Looks too high.
Here is the model: https://bin.0xfc.de/?6ee069bb3cb25d92#DCekNgztjPPpuPFM4DuoPfA48YaJurPPyHmpGENSknt3

Giovanni ZL2GX@KI5AYO Welcome. Two things that might be useful are remote SDRs (e.g. kiwisdr.com/public/) and pskreporter.info/.
The first lets you control a remote software defined radio (SDR) over the internet so you can hear how well you're getting out. Transmitting a carrier and looking at the remote S-meter reading can be useful for comparing antennas too.
PSKreporter is a site that reports stations it's heard using digital modes, possibly filtered with your own call. This also lets you see how you're getting out. The reverse beacon network www.reversebeacon.net/ does the same thing but listens for stations calling CQ in morse code.
Finally for a really deep rabbit-hole, have a look at the antenna modelling program MMANA-GAL www.youtube.com/watch?v=o_5H1E…. This enables you to get an idea of how well an antenna will perform before you build it.
There are lots of web resources and YouTube videos on the all of the above.
