Nice comparison of the two antennas.

Horizontal loops exhibit increasing numbers of radiation pattern lobes and nulls when operated above their fundamental design frequency. The New York station may fall in a null in your loop's radiation pattern while the Florida station is in one of the lobes. That may be why it hears one station and not the other.

That is true, but I have tested the loop verses the moxon in all directions (north, south, east and west) and the moxon is always 2 s units better than the loop. The loop is configured in a circular shape.

any directional antenna receive much less noise from other direction, on top of some gain on pointed direction , difference between signal gain and noise deduction are huge. AG6JU

What length is your loop?

The loop is 260 feet with a hybrid balun fed with LMR400, I have compared it to a 17 meter dipole and it beats a dipole every time.

@@johnwofford2708 What is the average elevation of your loop? Most people struggle getting past 30'-35' aka 10m. At higher than base frequency large horizontal loops typically show directivity in the direction opposite of the feedpoint. The typically low elevation makes them NVIS omnidirection at frequencies with an elevation =

What is "the loop"???? Meaningless unless we know what "the loop" is.

I said in the video that the loop is horizontal, 260 feet of wire in a circle configuration, up 25 feet. What more do you want to know???

I am sorry, my chemo brain has really messed up my mind. I just made a video where I gave the loop specs but in this video I did forget to mention the specs.... Sorry, I just finished my final chemo treatment and it really affects my mind.

No problem John thanks for the clarification and no need to apologize...I enjoy experimenting with antennas as you do and was thinking about a Moxon for 10m which is why I came across your video...continue to have fun!

The Moxon is really simple and cheap to build and has decent gain. I have worked the world on 5 watts with it... I made mine out of crappie telescopic fiberglass fishing poles. Have fun!!!!!
