So the 3000 is vastly superior to the 3000L in almost every possible way except one… antenna options and there it lacks horribly. The 60° Cambium horn for the 3000 is only 12dBi gain at best just so you know. We have tried using it in a few places but really the low gain just kind of kills it. The 90° sector has good gain but really it’s more of a 60° sector with really bad falloff (not fast enough for 60° but to fast for 90°) at the edges. However that “90°” sector is also the only option for using the “beam steering” antenna as far as I know (would it work if you mounted it under the dual horn ? Do the beam steering antennas even work correctly on 3000 yet ? Do they even really do anything when they are working ? Maybe someone else can chime in).
There is a 2 60° sectors covering 120° in one shell antenna. We currently have deployed 4 of them. They work pretty good as far as we can tell but they are very difficult to work with / very poor physical design
There are also some people using 2 RF Elements horns with the 3000 but it has drawbacks. Here is a thread on the subject and some feedback from Cambium:
Also keep in mind :
3000 has dynamic filtering 3000L does not
3000 is 56v 3000L is 36v
3000 and 3000L have sync but 3000L can not sync over power.
3000 can do beam steering 3000L can not
3000 has about 2dB better RSSI to MCS rate then the 3000L.
Personally I hate the 3000L’s they have caused us nothing but grief and angry customers but the 3000’s lack of antenna options really makes it hard to deploy 3000 in a lot of situations.
