Hello Guys,

Longer element length on beam antennas have been done before.

Infact "different" shapes in order to produce more gain has also been under investigation by the pro's.

I believe, if my memory serves me rigth is that a 1,5 wl long element which looked like a S was about "optimum".

There is of course the point where the mechanical effort doesnt serve the "extra".
And the point of the entire antenna pattern.
These days normal yagi's can be made with a very very tigth FB/FR which is often of more advantage than the slightly higher gain would be.

In aspect to the 5/8 wave length... im sure if you would google edz beam, or end fed zeppelin yagi you will come up with a couple examples.

Dont worrie to much about matching in first place.
The impedance of a antenne is about the only thing we can "solve".

Kind regards,
