I have never had a beam and am thinking of buying a PDL-2 or Moonraker 4. Is the Moonraker really that much better than the PDL? My objective it to talk 60 miles,station to station. Attached is a picture of my tower.It is 40' I think or a tad less.Is this tall enough for a beam to work well? There are no obstructions such as neighbors,trees,buildings etc.
