Hello All,

I have a question for the antenna design guys.

On a 4 element yagi, if the reflector turns
20 degrees on the boom will that make any
difference in the performance of the antenna???


ALmost unmeasureable difference in forward gain.

Nulls won't be as deep, but a pretty small difference.. hard to say numerically off the cuff, but you might go from a -30dB null to -20 or -20 to -15 dB.
