Do both antenna ports go to both radios? Which one is for which radio?
Installed in an high end RV, 5ghz used inside, 2.4 used to pickup wifi from outside....Would like to put an external antenna for the 2.4 outside. Just need to know which port is which.

Re: External antennas on hAP_ac3
Both antennas are used for both bands, if you want to pick up something outside, don’t use Antenna connection use another device like SXT
2,4 GHz

5 GHz

Re: External antennas on hAP_ac3
I would say the same thing, but im not trying to go distance...just 30-50 feet around the RV, and just with 5ghz. Would it be permissable to route the wire from one antenna to an external antenna and leave the other inside the RV? Or does the mikrotik need both in the same spot (For MiMo or similar)....?

Re: External antennas on hAP_ac3
If you use an extension cable to relocate the original antenna, the worst thing to happen will be that you lower the throughput per single device at 5 GHz (plus the outdoor signal will be reduced by the attenuation of the cable, not a big deal unless you use a really thin one). I'd expect the actual bottleneck to be the uplink at most sites, though.
You can test the amount of speed reduction in advance by setting tx-chains=0 rx-chains=0 (or tx-chains=1 rx-chains=1) for the 5 GHz interface and comparing the throughput of the same device on the same place to the default state with tx-chains=0,1 rx-chains=0,1. Before starting to tamper with that, check the default state, though: :put [/interface wireless get wlan2 tx-chains], there may be a different number of chains on hAP ac³ than on my hAP ac².
If you use a different antenna as the outdoor one though, it has to be a dual-band one as well so that you could use it to improve reception at 2.4 GHz as you've planned originally (which only makes sense if the attenuation of the cable is lower than the attenuation of the signal pass through the body of your RV).
Few more details regarding rx-chains and tx-chains can be found in the documentation.
An important point, be aware that by using any other antenna than the one which came with the device you are breaking the conditions of the FCC certification of the device, even materially if the other antenna has a higher gain than the original one in some direction by more than the attenuation of the extension cable.
