The optimum choice of antenna will vary according to application. The following table gives
some suggestions for suitable transmit antennas with the associated domo part number.
Application
Antenna model number
Mobile body worn application
1.00 to 1.40GHz - ANTBCL
2.28 to 2.50GHz - ANTBCS
Mobile vehicle application
1.00 to 1.40GHz – ANT4L
2.20 to 2.50GHz - ANT4S
5.60 to 5.90GHz – ANT4-560590
Long range point to point link
1.00 to 1.40GHz – ANT12L
2.28 to 2.50GHz – ANT12S
5.60 to 5.90GHz – ANT14-560590
Other antennas for more specialist applications, such as aircraft use or covert surveillance
use are available on request from domo.
Some of the antennas will require connector adaptors (Inter series RF adaptors) to connect
the antennas directly to the product.
2.13. Deploying the System
All external connection to the MESH products should be made, as described in the previous
sections, before proceeding to power on the system.
2.13.1. Installation Notes
This section gives guidelines for how to install the MESH node in the following applications.
2.13.2. Fixed position Applications
The Phase 1 and Phase 2 robust NETNode units are designed to be waterproof allowing
them to be installed outdoors.
2.13.3. Vehicle Applications
Interconnection between the unit and any antenna should be kept as short as possible, but
where this is not possible, special attention should be taken to use only low loss cables. An
appropriate cable might be RG213C/U. It is essential to minimise the distance between the
unit and the antenna. Mounting holes are provided.
Power conversion will be required for 24V vehicles.
The video input can be connected across long video cable lengths so remotely mounted
cameras should pose no problem.
The unit is self-cooling; however it should be mounted in a ventilated environment. Forced
air cooling is not required.
