Base Moxon

And Reduced Size and capture area of a "full-size" 2 element yagi...IMHO
Moxon work best Horizontal, can be mounted Vertical for local traffic.
Then you loose the noise reduction, of man-made interference mounting vertically
If the majority of your use was local, probably not the best choice, unless you have noisy neighbors. Very quiet backside.
Obviously wouldn't rival a 7 element Yagi for gain, but a good light weight, simple-ish, first time beam that can be made on a budget and rotated with an Armstrong rotor. If you like to homebrew.........

Agree with Crawdad. Guy 15 miles from me made a Moxon and everyone struggles to hear him.
He mounted it vertical. 12’ to the coax feed point. “Armstrong Rotor”.
He made it to talk 11 meters. It sucks. He has his Amateur Extra ham license. Been saying for a couple of years he’s going to raise the Moxon but hasn’t.

Please post your results and opinion, I for one would be interested to hear how it works for you DX wise.
Thx

A very fine dx antenna. Homebrew.
The key to any horizontal antenna is "height"... for DXing it needs to be high up...where verticals (if clear) can almost be "on ground".
I agree with those who are positive.
If i was forced to "pick" just one antenna and that only one would be there for the rest of my life....and i would not be able to change / touch it ever again....
It would be the Moxon.
1- It has 6dBi Gain...you will need to go to a 4...maybe 5 elements to notice the gain difference.
2- It has bandwidth..not only in SWR but also in "performance" (FB/FS/GAIN)
(some yagi's lack at this, "peak performance is great...but 500KHz in the other direction and its not that good).
3- There are NO parts that will breakdown ( refrashe that...breakdown easy hi... no gamma-matches etc).
4- It is direct fed, when constructed "heavy duty"...the amount of power it will handle is beyond what 99 percent will ever use.
5- it has a relative small footprint.
6-Maintenance is not an issue... sure a nice alu-brush is always welcomed ! but other then that ..it is a "worker"...always....a heavy duty moxon is very trust worthy.
If i wanted to complain ....it would be:
Beeing a 2el its opening 3dB beam-width is rather large... 10degrees rotating wont make a difference.....
Another "thing" could be...
It has to be carefully constructed/tested, the sizes of the antenna are a bit critical.
But if you have it "spot on" .... the back door is amazingly tight for 2el... and overal performance will be beyond what one expects from a 2el.
From my perspective...it actually is one of the few antenna...which is considered a compromise ...but due to that compromise it actually feels like an improvement... for me.. it isnt compromised at all.. im sometimes thinking it is optimized...and the "luck" which came with it ...is that smaller footprint.
Yes...there are better.... but without a doubt...im a fan !
Put time in it ...test/verify...and im confident you will enjoy !
Kind regards, H.

1. Did you use horizontal?
2. Did you optimize it fastidious?
3. Did you use aluminumb tubing? Far superior to wire model.
4. Did you get it up as high as possible above the ground?
They work at any height, but on a short pole like the majority with 24' more vertical antenna above the pole is not a comparison at all.
