On one repeater frequency at my QTH, the noise over-rides the signal. All other repeaters, even further away are fine. It was suggested that my QTH is in a null of its transmission pattern. The repeater "hears" me perfectly. That repeater is important because it is my organization's net check in repeater.
I'm currently using an omni-directional vertical for 2 meters/70cm. It has been suggested by several folks here and elsewhere that I try a small 2 meter yagi and test the limits of my HOA.

If I go that route, here are options:
1) Keep my vertical, plus install the yagi below it, run a SEPARATE cable to the shack and switch between the two in the shack. The yagi would remain stationary pointed at that useless SOB repeater.
OR
2) Eliminate my vertical, and install the yagi with a rotor.
3) Something I haven't thought of.
Your thoughts.
