We have a 900 Sm on a mountain top shooting approx. 12 miles. When
first installed we saw much interferrence on spectrum on upper end of band and
used lower frequency to get a link… (Quite a few towers with paging located behind us) Has anyone tried using an external filter or a corner reflector style antenna. We are using the antenna as shipped with the unit in a Horiz Config as recommended. When looking at last mile gear I see a filter that seems to
be a bandpass device which still will allow my interfering paging transmitter
to slide right through. Any thoughts???
