I would do something, but I have spent about 15 years designing products for specific radios only to have the radio manufacture knock it off, the radio go obsolete or competitors knock me off. Kind of tired in making radio specific products. So I try to focus on universal use products any more.

Or maybe the Wisp industry as a whole that has gone to bat for Cambium and has been with them from the Canopy days should leverage and demand a redesign of the High Gain to match is predecessors gain. I’ve gone round and round since we first got our hands on these and from day 1 I’ve been fighting for better. Supposedly there is a redesign (Q3?) that reduces the number of overall parts that should solve a few of our complaints but it’s not suppose to change the loss in gain. I’m going to continue to request they address the gain issue hopefully with others help we can get some traction R On Apr 14, 2019, at 3:25 PM, Ken Hohhof <[email protected]> wrote: Does Mimosa really offer up to a 25 dBi dish that just screws onto the radio which in turn is held by 2 hose clamps? That’s maybe OK for the smaller versions, but I don’t buy it for that large a dish. I see why KPP came out with their 1 and 2 ft dishes with a conventional mounting bracket. Costs more than $40 though.

I believe by “connectorized” cambium is actually going to release a device like the mimosa quick connect so it can use the same 3rd party dishes. But don’t quote me, that was from a brief conversation at the cambium booth at the last Wispapalooza. -Sean On Sun, Apr 14, 2019 at 12:17 PM Ken Hohhof <[email protected]> wrote: OK, connectorized 450b seems like good news. I wonder about the form factor. And whether it’s just a 450i without the special interference filter. 450b mid gain on a reflector dish does not, I can’t see how it would be optimized enough to perform better than a 450b high gain, it sounds more like a convenience factor that you could pop them into an existing dish. Any suggestions for a good CPE 5 GHz external antenna? Maybe Cambium should do a version of the 450b with a Mimosa quick connect waveguide coupler instead of connectorized, then we could use the KPP Pro Line dish. Still not sure if that is even shipping, their website says “check for availability”.

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. With 450b high-gain we seem to lose around 2 dB of antenna gain compared to the old SM and a reflector dish. And we recently tried our first 450m AP and found you really need to fix your low modulation subs first, or it’s like trying to drive a Ferrari on a gravel road. So my question is whether anyone is using connectorized SMs where you need more than ~23 dBi antenna gain, and if so, have you found an external antenna suitable for CPE applications? We tried a few of the Jirous dishes several years back and I was not happy with the mechanical construction. Has anyone tried the KP Performance “Pro Line” dishes, they seem to be mainly aimed at Mimosa applications but there is a version with N connectors. There is also the KPP feedhorn for their 28 inch reflector, I don’t think the coax connectors on the connectorized 450 SMs would reach, plus those SMs are discontinued now anyway, we’d have to use the very expensive 450i SM. For CPE applications I’d really like something that could go on a small diameter pipe like the leg of a customer TV tower, and I don’t want the installers messing with one of the designs where one set of bolts tightens the mount, the azimuth adjustment, and the elevation adjustment. It seems like the choice is mainly between backhaul antennas which are overkill and cheap CPE antennas which are crap. I know anything we do is going to cost enough to possibly eat all the profits from the particular customer, but I figure we need the sector capacity, and the cost gets amortized over the entire subscriber base, not just a handful of customers 6 miles from the tower on the edge of a sector. This has gotten to be a problem now that Cambium has lost us a couple dB with their latest designs at the same time that we need all subs on at least 6X because video streaming is making us really sweat frame utilization and sector capacity. -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -------------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
