No one do a table with dBm per every Band without any antena / with internal antena / with external antena like mANT LTE 50.
I have plans to do this tests in future and I plan go near to BTS like ~1km .
I do table from MikroTik Gain graph for SXTR/LHGR and post here this table with additional antena shape.
All u.FL are GLUE then those two are not perfect to do testing. If some one have got LtAP mini or M11G or wAPR etc. then pigrails and all other test can be done easy.
The glue est absolutely not sticky, it can be removed easily.
(I know that because those picture of the LHG are mine, I took them, I removed the glue without problem )
Back to the original question, actually I wanted the official gain pattern from Mikrotik, they must have them.
