In order to ensure your DualCom Pro achieves the best possible signal available we encourage you to complete the following steps.
Step 1 - Use a Signal Analyser to determine the optimum location for the aerial/s and follow the advice from the Signal Analyser section below.
Step 2 - If you do not have a Signal Analyser, power up the DualCom Pro, connect the aerial/s, go through the commissioning process and check the signal strength before permanently fitting the aerial. We recommend a signal strength on the DualCom Pro of at least 3 (30%)
STEPS 3 & 4 ARE ONLY IF YOU ARE FITTING A DUAL RADIO AERIAL.
PLEASE SKIP TO STEP 5 IF YOU ARE FITTING A SINGLE RADIO AERIAL.
Step 3 - If you are using a dual radio product, make sure that both aerials are at least 2 metres apart.
Step 4 - If using a dual radio product, position the aerials in a vertical orientation.
Step 5 - Keep your devices aerial/s cables away from high voltage cables or any other aerial cables.
Step 6 - Keep your aerial/s in open space and 1 metre away from large metal objects or sources of interference (i.e. wiring, lighting, electrical installations, computers, control panels, fuse boards, routers, etc.)
Step 7 - Do not tightly coil any excess aerial cable. Try and make large loops if possible.
See below for examples of good and bad single & dual aerial set-ups.

CSL SIGNAL ANALYSER - CS2389
Using the Signal Analyser, you must ensure that there are enough base stations (2 or more) available at the site and that they can supply sufficient signal strength (30% and above). This device will help determine the optimum location for the DualCom’s aerials to be mounted.
