On Tower Talk no antenna is ever sufficiently patterned, no tower base ever deep enough, nor wide enough, nor is cable greasy enough, nor is any guy anchored stoutly enough. Such is its nature. [Cori

Your low dipole, MAY be coupling to the yagi, that's the concern, right? And if so, if you detune it, the amount of interference would change. So my idea is to NOT go out to the antenna feedpoint and
