Sometimes when we get a certain combination of cold and snow at our transmitter site (on the HWS campus) then ice will form on the antenna itself. This causes the signal strength to significantly degrade until the ice melts. It doesn’t happen all that often considering this is upstate New York, but it seems like it was happening earlier this week.
We apologize for the degraded signal…and if it happens often enough we’ll start looking into solutions (either antenna heaters or radomes a.k.a. antenna slipcovers).
