2. Outdoor Unit
Figure 6. TX ODU
The TX outdoor unit (TX-ODU) is a UHF radio modem. It is supplied in a 'splash' proof
housing. If the TX-ODU is to be installed in open areas, it should be covered with
suitable weather proof housing. Great care should be taken when sighting the TX-ODU.
If it is to be placed above head height, approved safety harnesses should be used. If
the area is an open roof top, or other high vantage point, care should be taken to avoid
direct sunlight and or provision made for lightning protection. If in any doubt you
should consult with a local Civil Engineering bureau to check the requirements and
legislation applicable to your working environment.
In any event, the TX-ODU should be placed such that there is a clear line of sight over
the desired working area. UHF signals can penetrate through some objects, but
operation distance can be severely impeded.

The antenna is connected to the SMA female style connector on the top of the TX-ODU.
