Reducing number of elements in this design
 

Hi,

Would someone be able to advise me how I would calculate new dimensions
to scale the 9-Element Yagi
(described at http://www.qsl.net/ve3cvg/antennas/900b/index.html)
down to say a 4 or 5 element version.

(ie. I would like the same physical construction method and frequency
but shorter boom length - around 350mm), around 7dBi gain would be fine

Thanks in advance

Regards

David

FWIW, if you can't model the antenna and change the design, try
looking for someone else's design similar enough to make the change.

You may just try reducing the number of elements according to your
desired maximum length without much consequence.

Good luck
