Yeah I wanted to mention that when I started reading the thread.
Personally IP67 is not as important to me as simply being "rain proof",
and I have learned to have more faith in outdoor devices that have a
drain on the bottom rather than ones that try to be perfectly sealed.
If you've been at this long enough then at some point you've unscrewed a
cable gland and had all the trapped water pour out.
I also had a lot of warm fuzzy feelings for the 5 minute upgrade by
snapping a new SM on the same dish and same POE.
However, there could have been a big customer whispering (or screaming)
in Cambium's ear that they needed an IP67 SM.

I've seen a few used Force 200 radios come back from collection with a
broken tab on the cover. Also, we've lost a number of Canopy radios
over the years when rain got into them after the pole blew over or a
customer/competitor left it laying on the ground, so I'm all for a bit
more installation work to get the IP67 protection.

It looks like the 450b uses pretty much the same dish as the ePMP
Force 200... I wonder why they went with that goofy gland and bolt
on cover instead of just doing a snap on cover like on the ePMP.
I agree that the naming is stupid - they're doing the same thing
with the ePMP line now, with the Force 300-25 and Force 300-16
being the equivalent of the Force 200 and Force 180. The old way
was easier...

My complaint is not about the integral dish, but the specific
implementation of the cover and gland. The 450d was not a
problem. The 450b mid gain is not a problem. Naming them both
450b was stupid though.
BTW, note that it’s not really 25 dBi, didn’t they finally
fess up and change the spec sheet to say 23 dBi?
I also quibble with the characterization as “cheapo” and
keeping costs down. Depending on which license key you were
buying on the 450 SM, the cost ends up being about the same as
the previous SM plus a reflector dish. Of course if you are
replacing FSK or 430, you already have the dish, and now you
have to remove and replace it rather than taking 2 minutes to
pop in a new SM without even needing to realign.
I’m waiting for the first time we have to replace a 450b high
gain due to something like lightning damage. That would mean
removing and replacing the radome, which BTW is almost
impossible in cold weather, I have actually had to use a heat
gun to warm them up so they are flexible enough to go on. So
I assume now we end up replacing the whole dish assembly and
realigning. Not much point trying to save the dish anyway
since you have to buy the SM and dish together.
The other goofy thing is how inconsistent Cambium is. Even
the two variants of 450b are different, and the other
frequencies (900, 2.4, 3.65) are totally different. And of
course now when we replace a 450 AP the replacement is a 450i
AP which requires 48V rather than 24V. There really seems to
be no master plan, just flavor of the day. The only
consistency seems to be carry a 13mm wrench and a 5mm hex key
with you. Or an electric screwdriver with a 5mm hex bit, or
your hands will get tired. My guys complain about how long
the threads are on the screws for the hated cable cover.

To a point I agree. Look at how much nicer a 25dbi dish is
over a reflector+patch radio, though. It keeps costs down
(since everyone's doing the cheapo 25dbi instead of trying to
get by without a bare SM). Gain is good.
Ubnt Nanostation copied the Canopy idea, mostly. They moved
to dishes. Cambium had to "catch up" with the WISP world.
My perspective may be different though - we almost never
install bare Nanostations/Force 180/bare Canopy radios. We've
always had to do reflectors/dishes.

It drives me crazy that Cambium continually spends more
time staring at what other companies have done and trying
to copy them than looking internally at what made their
own products the best in class.
The original Canopy case design was damn near perfect -
inverted cup that didn’t fill with water. Easy to remove
and replace. Lots of mounting options.
And now we have lots of little parts to drop. Reminds me
of exactly what I hated about WiMax gear.

I hate it too. Seems like they should have that
design for ePMP and something nicer for 450. =)
What would be nice is a door with a hinge, so there
aren't multiple pieces you can drop and ruin your day.

Does everyone hate the 450b high gain cover with

they felt the need to do this on the high gain but
not the mid gain.
I wish somebody (Chuck?) would sell an aftermarket
conversion kit to make it like the mid gain or the
original Canopy SM. With a snap on cover, water
kept out by gravity, and readily accessible
alignment tool port.
There are other mechanical things I hate about the
product, like the screw in the back that you have
to tighten ever so gingerly, and the 4 threaded
inserts that seem to have manufacturing quality
issues like getting covered over with plastic. Or
the occasional feedtube that doesn't quite want to
latch into place. Or how much work it is to
convert them to mount on the left side of the
pole. But the stupid cover with the cable gland
is an annoyance every single time.
