Mike, in reading your original post I'm unclear if the above comment refers to a DB408 or one of the glass Diamond sticks. Anyway, there will be no up or downtilt with a 408 because the dipoles are fed in parallel. The pattern does become broader, with a decrease in gain at the horizon with departure from the design range. As others have said, they still do work very very well in the ham band. The series-fed types (usually fiberglass at these frequencies) *will* tilt their patterns when moving away from their design frequency. Laryn K8TVZ
