Just got our first 3000L, no puck, no connector cap. cant sync to any of the 40+ visible satellites that a 1000-lite could in the same spot. Now take it outside instead of by the south facing window and at ground level it sees 12 satellites.
the planned install location has a packetflux powerinjector plus's which provide the cambium sync signal. BUT we do use the internal GPS for safe-guarding against sync failures.
Maybe Cambium should give out another part number that will have a puck shipped with the radio? At least my distributor does stock the correct talgos puck so I can at least add one to the order now that I know it doesnt come with one.
On another note, I have found sma dust caps through both mouser and digikey as well as ebay. Just make sure its just a dust cap not a terminator or you can have issues if the circuitry is not designed to deal with the terminator. If any one needs a few dust caps, I will have some available in two weeks. These are coming with a little chain and screw anchor to hold the cap from being dropped. I plan to use the grounding screw as the anchor attachment location since it is right beside the sma port.

Do they make pucks with 100ft+ cords ? What do you do when you have to mount a 3000L on the dark side of huge water tank or the dark side of a silo or building or you have the mysterious Cell Tower interference all over your service area....
Probably might order some GPS pucks just so you have them on hand. We are not having very good results with GPS sync and 3000L's without the puck. Small sample size here so YMMV, I have... 7 3000L's deployed right now and have had to go back and put pucks on 3 of them and then two that don't require tower climbs I just went ahead and put pucks on. Really frustrating , to puck or not to puck... that is the question. We are hesitant to put pucks on them because in the past Cambium blamed the pucks for the 1000's and 2000's losing sync ( I have half a dozen 1000/2000 GPS radios right now that aren't seeing/tracking enough sats to maintain sync but we don't care because we sync them over power. Some have pucks some dont' because at one point we quit putting pucks on them because we were syncing over power) I really don't know what to do here.
After the first 3000L we had trouble with, even though it did not appear to have water in it when we went back, we put caps on them filled with dielectric grease now. Didn't seem to make a difference, and water didn't seem to the problem on the first one anyway.
I've watched the two with no pucks dip as low as 8 sats tracked. I don't remember how many they have to track to maintain Sync but I think the 1600s holdoff time is the only thing keeping them going sometimes. My current graphs average the number of sats visible/tracked so short dips into just a few sats don't really show up so they could be regularly dropping lower than I know. I was going to put something together that doesn't average but I'm leaning more towards just replacing the 3000Ls the first time one with a puck loses sync... meanwhile I'm looking for something else to use when we need just a few 100Mbps on a backhaul and an sector solution that will allow us to use the 3000 when splitting/Upgrading APs.
Thing is I would rather have a dual 65° sectors in a single shell configured to cover 120° and than a 120° sector with MU-MiMO because the 2 non MU AP's don't care if the radios are N or AC or if they are separate by x° in order to double capacity . Not to say I have no use for MU , there are some places it would be the better solution but most places I would rather have 2 AP's that don't need magic to sometimes, usually, a lot, maybe, talk to 2 AC radios at once. 3000L is not that radio though...
the 3000L will not sync to a canopy timing source. The 3000L will only recieve sync from the cmm5, ugps and select packetflux power injectors that provide the CAMBIUM SYNC method. This is the same as the pmp450 (the 450i will do either).
RP-SMA and LMR100 is my solution to needing a puck cable extension. The added 50ft cable length ( all I have for now) did not seem to make a difference to the puck since it does have an LNA in them which is powered over the cable (same way as your sat-tv dish). I am sure at some length the LNA will not get enough power or the signal from the puck will be useless, just dont know how much yet.
As for MU-MIMO, I still havent found a use for it. Even the old epmp1000 was still fast enough for our use cases ( so far anyway) and the 3000L cuts the sector count from 128 to 64 ( 70 to 45 usable) so there is still plenty of time to service all SM's with reasonable dispatch. I could see in a sub-urban sprawl where you may have maxed out sectors that MU-MIMO and beam steering are a good option, but so is narrow sectors and more AP's.

Hmmm you must have a special radio :-) There were some people complaing about CMM5 and packetflux not working with 3000L's and Dmitry from Cambium said "ePMP3000L doesn’t have hardware to support CMM, only GPS." and there's no option in the GUI to select an ethernet timing source... so yeah... dunno how yours is working.
