Install the AP300
Install External ACC-ANT-MIMO-MNT Antenna with Three Connectors
(optional)
You can optionally use an external antenna setup with your AP300 if the controller and APs are running
System Director 3.6.1MR4 and later. Meru supports this antenna for use on one radio using 802.11n
MIMO. An AP300 with one radio, for example AP310, needs one antenna. An AP300 with two radios, for
example AP320, needs two antennas. Radio One antenna cables connect to ports A1, A2, and A3. Radio
Two cables connect to ports A4, A5, and A6. There is no preferred cabling connection; all three cables
are the same.
Calculate the antenna gain for the ACC-ANT-MIMO-MNT antenna by referring to the next three charts:
Band of Operation Gain Vertical Beamwidth Horizontal Beamwidth
2.40-2.483 GHz 2.5dB 55 degrees 360 degrees
5.15-5.85 GHz 4dB 60 degrees 360 degrees
Using This Cable Type with 2.4 GHz Calculate This Loss per Foot
RG174 0.60 dB
RG316 0.48 dB
LMR100 0.39 dB
LMR200 0.17 dB
LMR240 0.13 dB
LMR400 0.066 dB
LMR600 0.043 dB
Using This Cable Type with 5 GHz Calculate This Loss per Foot
RG174 1.02
RG316 0.76
LMR100 0.59 dB
