Yeah, you need room for the SM to hang down.  With a standard J-pipe, not only 
is there not enough room for both U-bolts, but there is an annoying tendency 
when you go to aim the yagi for the angled part of the J-pipe to be right where 
the SM needs to be.  I need to find one of the reversible pipes like you refer 
to that has the same bolt spacing as the standard ones we use, so we can swap 
pipes in the same base, when changing from FSK to 450i.

Oh, there’s another thing, we never have to buy J-pipe mounts, because we get 
one with every reflector dish, which end up surplus when we use a tripod, 
M-TOW, or a piece of pipe in 2 wall mounted W-brackets, or some other mounting 
method.  So if we start using a lot of 450d’s, eventually I assume we will go 
threw our pile of J-pipes and actually have to buy them.

I suspect 12" isn't going to be quite enough for the 900mhz 450i antennas. 
There are shorter J-pipes that can be reversed, so you have a taller vertical 
section... I would think that would make more sense than cutting down a 39".

  I’ll have to check that the 450d will mount on a 2” mast.  The sat dish

stay with the 1.66” masts which are a bit flimsy.

  I’ll have to check if the 450d will go on the Direct TV stub mounts, they are 
only 12 inches high, so maybe not enough clearance off the roof.

  I’m also curious if the stub mount will work for Cambium’s 900 MHz 450i 
antenna which BTW I like very much, but a standard J-pipe is not a good mount 
for them.  We end up using the Winegard DS-3000 and cutting them down, the 
result is ideal, but it’s a waste to buy an expensive 39” J-pipe and cut it 
down.  And a 2” pipe would be that much sturdier.

  Well, reflector dishes have their merits.  I have upgraded from Trango, FSK, 
430, 450 sometimes twice by just popping a new radio into the existing dish.  I 
have changed frequencies.  You can bring one radio for use as standalone 
“integrated” or if you don’t get the numbers you want, pop on a CLIP or use the 
same radio with a reflector dish.  It also reduces the number of spares you 
need to keep in the truck for repairs.  Another advantage over many of the 
integrated dish solutions is the mount provides independent adjustments for 
elevation and azimuth, which lends itself to better alignment, and reduces the 
need to hire 3-handed installers (or monkeys with prehensile tails).

  Visually, one may look better to some, but the eye is so used to seeing 
satellite dishes that one more reflector dish goes unnoticed.

  Cambium is moving towards EOL the reflectors from some of the roadmap stuff 
I’ve seen.  I think the ePMP Force 200/450d type configuration and Force 180 
design are here to stay.

  So over reflectors.  Love to see lower priced versions of these and the 
reflector crap phased right out.

      I have gotten 5db better with the 450d also inner feed designed dishes 
seems to work much better when under a tower also much more simple to mount on 
a tower I hope they do the same with 2.4 and 365 soon

        We love it! We have standardized on it 

        -looks way better that a SM+dish, more professional

        -gain the same or 1-2db better

        -easier to assemble / align 

        -less windload

        I see several WISPs deploying the 450d, but I suspect it's because they 
don't like reflector dishes, or because of the 40M license key.

        Cambium has indicated the 450d has a little more antenna gain than the 
regular 450 SM plus a reflector dish, but the spec sheets say 25 dBi either 
way.  What are people really seeing in the field?  Is there a performance 
difference in an apples-to-apples comparison?  How much?  I'm not going to get 
too excited about 1 dB.

        Otherwise, we're looking at the connectorized 450 SM.  Or the 
connectorized 450i SM, which is pretty pricey.
