Anyone tried the midgain 450b in a reflector? Btw: who’s in charge of naming the SMs… 450b mid and 450b high is a stupid thing….

But not surprising about the mid-gain version that looks like a rearview mirror, the vertical beamwidth is too wide. I know the CLIP was not popular, but we actually had very good luck with it. I’m also struggling with the 450b hi-gain. The xmt power is supposedly 5 dB higher but the antenna gain 2 dB less than the original SM with a reflector dish. Maybe that’s an improvement if you have a lot of interference at the AP end, although a 450m should mitigate that. I can’t convert everything to small cells, so 2 dB less antenna gain is not the direction I want to be going. It also drives me crazy now with a mix of 450 and 450b SMs on a sector that you can’t pay attention to the signal power in the Sessions tab. The 450b SMs have asymmetric xmt power, so they may look OK, but then you check the signal at the SM and it’s often less than expected. Unfortunately, Cambium intends to discontinue the old SM form factor. That means what might have been popping in a new SM becomes replacing the whole dish. While the 450b hi-gain looks attractive and the radome is nice, I wish Cambium would just put the new 450b electronics (tri band, more CPU power, higher xmt power) into the old SM form factor.

Tired of throwing away $250 SMs every few years. I think you will find 450b’s are not a drop in replacement for regular 450 SM’s with reflectors or 450d’s. Lower gain and seemingly more sensitive to reflections when mounted in normal locations on a building. Replacing them now would be painful. Mark
