External Antenna Guidelines

NOTE: Doubling the E.R.P. does not double the range of an antenna.

External Antenna Selection Criteria

The following sections identify the factors to consider when selecting the type and location of external antenna to use with your OMEGA unit.

Antenna Placement

The method and quality of the antenna installation impact the clarity and reliability of cellular signal reception and transmission. Always strive for optimal antenna placement.

Distance from the Antenna to the Closest Cell Site

Find out the locations of all nearby cell sites. This information will help you position the antenna for maximum performance. Contact the local cellular carrier to obtain this information.

Degrees of Down-tilt on the Cell Site Antenna Array

Contact the local cellular carrier to find out this figure. The greater the down-tilt, the closer your antenna should be to the cell site or the higher gain antenna you need.

Obstacles between the Antenna and Cell Site

Natural obstacles such as mountains, hills, and trees between the antenna and cell site can cause signal deterioration. In some instances, the signal can be blocked completely. To compensate for natural obstacles, move the antenna location, raise the antenna height, or use a higher gain antenna.

Man-made obstacles can also affect cellular performance. Check the path between the antenna and the cell site for tall buildings, water towers, and other construction. To compensate for man- made obstacles, move the antenna location, raise the antenna height, or use a higher gain antenna are ways.
