Fine-Tuning Antennas - Wi-LAN Hopper Plus 120-24 Installation And Configuration Manual

Antenna Basics

Fine-tuning Antennas

You can fine-tune the antennas by physically moving the antenna. When the remote antenna is correctly
aligned, the AIR LED is orange, indicating communication with the base station. You can use the Receive and
Transmit Tests to test the link while adjusting the antennas to minimize BER and lost packets and maximize
received power. You can use the RSSI Test to maximize RSSI.
Once antennas are adjusted to maximize performance, secure them properly to the support structures.
Co-locating Units
When Hopper Plus antennas are located on the same mast, you must take care to ensure the output power
from one radio does not overpower another co-located bridge, even if the units are operating on different
channels. You may need to install a signal attenuator to lower transmit power, use antenna polarity to your
advantage, or adjust antenna uptilit or downtilt. Contact Wi-LAN Technical Assistance Center for antenna and
installation assistance when co-locating units.
