Question: How to identify by looking AP 104 that which Antennas are A0/A1 and Radios are R0/R1?
AP 104 has 4 connectors which are used for external antennas and out of 4 connectors; 2 for each band/radio.
At the beside of connectors it's tagged each antenna ports however if it's not there below picture tells which one is which.
The AP 104 is designed for use with external antennas and equipped with four external, female RP-SMA antenna connectors.
Antenna connector mapping:
R0/A0: Radio 0 (5 GHz), chain 0
R0/A1: Radio 0 (5 GHz), chain 1
R1/A0: Radio 1 (2.4 GHz), chain 0
R1/A1: Radio 1 (2.4 GHz), chain 1
R0 = Radio Zero
R1 = Radio One
A0 = Antenna Zero
A1 = Antenna One
