3M™ Wireless Communication System Model XT-1

Technical Data - #121

3M™ Omni-Directional Digital Range Extender 78-6911-4971-6

PURPOSE

3M is pleased to introduce the new Omni-Directional Digital Range Extender, which provides Omni-directional

radio coverage from one antenna.

Purpose

To enable extended coverage area for "outside order taking" or "fill in" areas of poor radio coverage due to

blockage of the RF signal by large metal objects. Extends working distance from the digital system base

station.

Radiation Pattern

The 3M™ Omni Directional Digital Range Extender Model XT-1 has an Omni-Directional antenna, which

means it radiates the radio signal in all directions in the horizontal plane, however its vertical plane radio

coverage is very limited.

When to use the Omni Directional Antenna and when to use the patch antenna

3M recommends you use an Omni Directional antenna if you need coverage in two adjacent areas, such

as two sides of a building; 3M recommends the a patch antenna (78-6911-4691-7) if you require radio

coverage in one area, such as one side of a building. An example of when 3M recommends the use of an

Omni-Directional antenna is listed in Figure 1.
