III. Mounting the video hub’s External Antenna

For professional, reliable installations, the video hub should use the external

antenna supplied with the unit. The MicroPower external antenna kit comes

complete with a low loss RF cable, 2:1 splitter and a directional antenna. For

optimal results, the height of the external antenna should be mounted above any

pedestrians, vehicle traffic, trees, or obstacles that may block line-of-sight between

the video hub and wireless camera(s).

The directional antenna supplied by MicroPower can transmit and receive in both

the 900 MHz and 2.4 GHz frequencies. However, the 900 MHz and 2.4 GHz

channels from the video hub must be combined before being connected to the

directional antenna. In order to connect the channels together, a 2:1 splitter

(included) must be used.

The 2:1 splitter must be connected as shown below. The output of the 2:1 splitter

is connected to the low loss RF cable.

This will generally simplify the installation, by not requiring that the installer mount

and configure two separate antenna solutions, and not requiring that two

independent antenna cables be used.
