Re: 96.3 OFM 209km D-808 with yagi aerial
Yagi's offer antenna gain but they also have the benefit of directionality.
Verticals (whip)s are omnidirectional) and offer no opportunity to null out. Dipoles have a figure-eight pattern and have two opportunities per rotation for nulling. Yagi's have a cardioid pattern and so are unidirectional giving the best opportunity for nulling.
If anyone is having trouble with pest stations on or near the frequency of interest, a yagi might be the solution depending on the relative directions of the two stations.
If the yagi overloads the Rx, an attenuator is a simple construction.

Could you provide more info about that use of a yagi with the little D-808, and your overall opinion of the results?
