    how close together are the antennas? are they on the same channel?? try
    moving the antennas as far apart as possible, or orienting them at 90
    degrees to each other and see if that helps. also put them on different
    channels, there are some channel combos that are better than others for
    preventing interference, i forget the best ones now but they are on the web
    somewhere.
