I have an LTAP and I can see in the wifi settings that you can choose which antenna, A or B to use. I don’t see anywhere on the board that indicates which is A and which is B. Can anyone shed some light? Included a picture in order to reference.
Just stumbled on this thread… did you ever find out the answer?
Is it possible to use external antennas for 2.4GHz?
Never have found out the answer to my question. To answer yours, yes you can use external antennas. The connectors are the ones circled in my photo. If you need some connectors so you can attach SMA antennas I can send you links to the ones I use.
Thanks 43north!
@43north, have you tried to find out on your own?
By setting tx-chains=0 rx-chains=0 on the wireless interface, you can restrict the use of the radio to a single chain = antenna connector. If you connect one external antenna directly and the other one via an attenuator, /interface wireless scan should show you the difference as compared to the tx-chains=1 rx-chains=1 setting (if you have some other APs nearby of course). If you have no attenuator, a comparison between a directional antenna and an omnidirectional one will do the same job.
No I have not gotten that deep in testing it yet. Great ideas and thanks for the commands to run the tests. When I originally posted this I thought for sure someone from Mikrotik that has access to schematics would easily know which is which.
Seems they are labeled JB00 & 01, thinking 00 should be A and 01 B, but no guarantees
