4 Mounting the Antennas
PureWave Quantum Base Stations can be deployed with virtually any type of antennas that operate in
the relevant frequency band and that meet regional regulatory standards. Because the PureWave
Quantum 6600 base station supports six antennas, the easiest and most cost-effective solution is to use
a PureWave 6-Port Antenna Panel in the appropriate frequency band. By combining six cross-polarized
antennas in a single compact radome it reduces deployment real-estate and greatly simplifies
installation effort since only a single mount is required.
Antenna mounting procedures will vary by model and manufacturer, so we refer the installer to the
instructions that came with the antenna(s) and/or antenna mount(s) for their secure and proper
installation.
The PureWave 6-Port Antenna Panel is shipped with a pole-mount kit and installation instructions. Note
that if you purchased a PureWave 6-Port Antenna Panel then the Antenna and Mounting kit were
shipped in a separate box from the base station. A pole-mounted PureWave 6-Port Antenna Panel is
illustrated in Figure 12.

As a general rule the antennas should be installed as close as practical to the base station. This
minimizes signal loss which is directly proportional to cable length. In addition, a high-quality, low-loss
coaxial cable capable of propagating the relevant frequencies (such as Hyperlink Technologies P/N
CA3N100 or Times Microwave LMR 400) should be utilized between the antenna and base station.
In the event that the base station cannot be co-located with the antennas the choice of cable is even
more important, as signal losses can be significant. For example, LMR 400 cable has an attenuation loss
of 6.8dB per 100ft at a frequency of 2.5GHz. It is important that cable loss be computed and understood
to ensure that adequate range will still be achieved for your deployment needs.
