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.
