Digital Range Extender

78-6911-4961-7

Installation Instructions

PURPOSE

To "fill in" areas of poor radio coverage due to blockage of the RF signal by large metal objects and to extend working distance from the digital system base station.

Radiation Pattern

The Digital Range Extender is not an omni-directional antenna similar to 3M’s previous Signal Enhancer; it is more directional. The attached diagram shows its Radiation Pattern.

How to determine the proper location of the antenna

You can visualize the radio coverage area of the Digital Range Extender as a cone with a 75 degree dispersion whose starting point is the antenna. Attached is a two dimensional drawing of the antenna radio coverage, where the area inside the triangle has radio coverage.

Antenna

Radio Coverage Area

Width = Target Area

75°

The first step in achieving adequate radio coverage is determining the area where the customer requires increased operations. Once the area has been identified, the distance of the antenna from the target coverage area is calculated as follows:

Target Area = Distance * 1.5

Example:

If an area 15 ft wide needs radio coverage, the antenna needs to be at a distance of 10 ft or greater in order to have adequate radio coverage.

EQUIPMENT NEEDED

• Wire (18 Gauge recommended) to connect lighting arrestor to Earth Ground

• Mounting Hardware for antenna

BILL OF MATERIALS

• 78-8117-4330-7 – Pigtail - SMA Male to N Female Adaptor Cable (90deg.)

• 78-8117-4331-5 – Lightning Arrestor (N Male to N Female)

• 78-8117-4332-3 – 2.4 GHz 8 dB Round Patch Antenna (Female)

INSTALLATION WITH A DIGITAL WIRELESS BASE STATION

1. Remove the Base Station cover

2. Disconnect power to the Base Station

3. Remove either the left or right base station antenna

4. Connect the pigtail to base station antenna connector, in spot where antenna was removed 3M Building and Commercial Services Division

NOTE: DO NOT use a tool to tighten the pigtail to the Base Station, leave the connection finger tight.

5. Connect coaxial cable to pigtail.

NOTE: Be sure to form coaxial cable into a "drip loop" and secure to mounting surface when connecting to Remote Antenna

6. Reconnect power to the Base Station

7. Attach the Base Station Cover.

8. Locate the area in which enhanced radio coverage is desired

NOTE: Obstruction-free line of sight to headsets is required with no large solid metal objects between Remote Antenna and headset.

9. Pull the Coax Cable to desired antenna location.

10. Connect the lightning arrestor to Coax

11. Connect the lightning arrestor to antenna

12. Test the system range.

• Have someone hold the antenna in the selected location

• Verify antenna operation in required area

• If necessary reposition or move the antenna in order to get desired coverage

13. Mount Antenna in location in order to get desired coverage

14. Mount the lightning arrestor

15. Run 18 Gauge wire from lightning arrestor to an Earth Ground

16. Test the system range.
