Okay I haven't paid a lot of attention to PMP450 since I've been in a Telrad 
shop for a few years. It looks like the old style SM was discontinued.

The Old SM + Reflector was said to have 25dbi of gain.

The replacement 450b "high gain" integrated dish is 22dbi.

Are you kidding me? Cambium, why you takin' my db's away bro?

Just remember…
When anyone at Cambium gives a time frame, you can add 6 Months to a year.
If you want to be amazed, they will announce next year.  Release 3 Months in 
advance and with working firmware.

AT THAT POINT, we can be amazed.

Maybe they just need to go with something like TwistPort and let 3rd party 
manufacturers sell dishes.  Oh, right, regulatory approvals.  Nonethless, I

Re: [AFMUG] 450SMs

[Ken Hohhof]

Yeah, a one year delay is a pretty big oops, but it’s not really a solution to 
the problem anyway.  Except that 450b gets rid of the hated speed caps and also 
enables 5.1 GHz sub band.  I’m not thrilled about SMA connectors on the top, 
KPP included a nice mounting post for the current style connectorized SM, I’ll 
have to see if it still works with the new SM.

 

What they probably need is a slightly larger and also deeper parabolic dish, 
get the gain back to 25 dBi, and better sidelobe performance.  Or get to the 
bottom of why the 450d/450b style dish seems so much more susceptible to 
reflection and multipath degradation.  I think Cambium expected higher xmt 
power would compensate for lower antenna gain, but that does nothing for 
downstream.

 

I heard a rumor they were redesigning or eliminating the cable gland?  Was that 
mentioned at Wispapalooza?

They are coming out with a 450b connectorized but at wispapalooza they said it 
was delayed until March 2020 (it was supposed to ship March of 2019)

The replacement 450b "high gain" integrated dish is 22dbi.

Are you kidding me?  Cambium, why you takin' my db's away bro?

I'm ok with the cuteness factor of the 450b.  I just think they should 
offer a full 2 footer also.  Yeah the 450i + a dish + jumpers has got to 
be $700-$800.


I wonder if it's the same marketing error as New Coke.  In testing 2/3's 
of customers preferred the new formula.  Fuck the other 1/3, they don't 
matter.

It seems to be part of a strategy of sharing designs with ePMP but

Customers do seem to like the aesthetics of the 450b dish.  Swapping 
for left-of-pole mounting is a giant pain, especially after you’ve 
attached the radome.  And installers complain about not being able to 
see the lights. What’s strange is we still use reflector dishes for 
the 3 GHz SMs.


FWIW, we have solved performance issues with the 450b high gain by 
swapping in a connectorized SM and one of the KP 2 ft Proline dishes, 
but that’s a big and godawful expensive solution.  Strangely the 
performance increases more than you’d expect from the signal level 
alone, maybe some kind of sidelobe issue?

If the 22 is somehow better than the 25 then they should update 
LinkPlanner to show me that magic.
