I see several WISPs deploying the 450d, but I suspect it's because they don't like reflector dishes, or because of the 40M license key.

Cambium has indicated the 450d has a little more antenna gain than the regular 450 SM plus a reflector dish, but the spec sheets say 25 dBi either way. What are people really seeing in the field? Is there a performance difference in an apples-to-apples comparison? How much? I'm not going to get too excited about 1 dB.

Otherwise, we're looking at the connectorized 450 SM. Or the connectorized 450i SM, which is pretty pricey.
