Aerial Siting
This 'DualCom, aerial & battery' method can not provide information on the
availability, signal strength and interference status of all radio Base Stations in
the surrounding area. Use of the CS2366 Radio Test Set is recommended.
Alternatively, a Vodafone mobile phone may be used to locate the point of
strongest signal. The signal strength indicator is normally a bar or line at the
side of the display on the mobile telephone. Note: The mobile phone MUST
use the Vodafone network. A mobile phone that uses a different radio net-
work will NOT show the correct signal strength.
This 'mobile phone' method can not provide information on the availability, sig-
nal strength and interference status of all radio Base Stations in the surround-
ing area. Use of the CS2366 Radio Test Set is recommended.
When you have identified the point of the strongest signal, make a note of this
point and use it when installing the DualCom aerial.
Remember: It is always easier to find the point of strongest signal before the
equipment is fitted to a wall. Moving aerials, cables, trunking etc. after installa-
tion is wasted time and effort.
