We have some old connectorized PMP100 5.2ghz (5250AP) AP's that we would like to use for an area which doesn't need a lot of bandwidth. Can someone give me some options for Omni directional antennas from 10-12db that will work well with a connectorized 5250AP?
We at Cambium really don't have any experience with these, but many of our customers have done this through the years.... a couple of examples of antennas I found are linked here (but again, sorry, I don't have any recommendations. Hopefully, a fellow user can chime in):

Thanks for the reply but those antennas are 5.8 and 5.4-5.8. Neither appear to be the full 5ghz band or the 5.2ghz ranges. I think that is why I am having trouble finding omni's for the 5250AP.

Yeah, I don't think he'd want that omni assuming he's using integrated SM's. All the 5GHz integrated SM's use horizontal polarity. What about using a KP omni? Yes, they're dual-pol, but you could just use the horizontal polarity and tape off the other. That, and they support the lower 5GHz band as requested.

Actually, I am pretty sure the SM's are Vertical pol. The problem is that these antennas were 5.8ghz not 5.2ghz. I hadn't thought about buying a dual pol and just using one port. It looks like KP makes a 13db omni that works from 5150 - 5900MHz although the link appears to be broken so I am not sure if they are still making it. After doing some additional research, it looks like this might be a good one also that is rated down to 5.2ghz ranges. IT Elite OMD50012V. Anyone have any experience using these in 5.2ghz? Am I right about VPOL?

It depends on what you ordered, there were h-pol options for all the 5GHz SM's.... PMP100 2.4GHz SM's were v-pol, but maybe someome from Cambium can chime in on this:
PMP100 5GHz was always v-pol. To get h-pol, you needed to order them specifically and made sure your reseller/distributor got it right. The h-pol radios have HZ in the model number. For example, a standard 5.7 with the horizontal patch was 5700SMHZG (P11) or DD (P10). The standard v-pol was 5700SMG or SMDD.
By far the best performing 5GHz V-pol antennas I've used are Larsen. 10dBi, very clean pattern and good vertical beamwidth.
They are sub-band specific. So if you want 5250-5350MHz, order an RO-5210. 5410 for 5.4 and 5810 for 5.8.
They are the same antennas that Last Mile Gear uses on the Cyclone 360's. Larsen made custom models with black radomes for LMG. You can call to order them directly with LMG. The models are ROB-5210, 5410 and 5810.
But honestly, what we've been doing lately to replace failures is just using a KP omni and putting the AP on the vertical port only and capping the horizontal port. We do very few if any omni's anymore though. We don't put up any new PMP100 either. We just keep the existing stuff running until we can get things scheduled for 450.
George,
Thanks for all of the information. I found the Larsen RO5210NF which looks like a great antenna but it doesn't look like there is a way to mount it with a connectorized AP. It looks like a screw on type antenna where the N connector is what secures it to the radio. I will check out the KPP antenna dual POL's and probably go that route.
Thanks,
Brad
