Cambium is going to release a 450b connectorized. Also KP had a photo leak of a bracket that puts the 450b mid-gain on their reflector dish.
Hopefully both of these become a reality sooner rather than later. -Sean On Sun, Apr 14, 2019 at 10:06 AM Ken Hohhof <[email protected]> wrote: > With Cambium discontinuing the 450 SM we have only the 450b and the pricey > 450i SM to choose from.
