Is there a radome for the RF Elements dishes?
If we don’t use a radome, they fill up with snow on days like today
when we got several inches of wet snow even though it’s April 14.
Gino, I realize snow is not a big problem for you. But we also have
birds that like to sit on feedtubes. Plus radomes help with wind load
and aesthetics.

450b connectorized supposed to be like this: Compatible with RF
Elements waveguide adapter. We use their dishes! They are good stuff.

I completely understand Chuck
As for Who, we’ve spoke to Many at Cambium including Matt and our
sales rep whom have been excellent so I’d start there. We’ve even had
engineers onsite doing ride alongs with our installers.
I’m anxious to see the big gain models coming with less parts and I’ve
requested to be part of the development of a third revision which
Hopefully will increase the gain.

Kind of tired in making radio specific products. So I try to
focus on universal use products any more.

Who do we need to beat up? Are you talking to your regional sales
manager, or the 450 product manager who I believe is Matt?

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

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.

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.

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.
