Step 2. Using the CM240-M
Use the CM240-M cable FME connector to connect the outside antenna to the
boost connector marked OUTSIDE (see page 3).
Make sure to not coil additional coax cable that might be left over from installa-
tion. Hand tighten the connection.
Before installing Indoor Antenna check the table below for optimum
coverage.
Step 3. Connect the Interior Antenna
Option 1: Standard Wireless Usage (Recommended)
The supplied 248W-M full-band antenna is a compact directional antenna de-
signed to cover 2G, 3G, 4G and WLAN systems for Cellular, PCS, AWS and LTE
frequencies. It’s a high-gain indoor antenna suited for places where the signal
needs to be broadcast over a wide area. This interior antenna transmits and
receives signals to cell phones.
1. Choose location for mounting antenna on vertical surface. Ideal height from
the cabin floor (should be approximate height of cell phone users).
Note: As you can see from the table above, acquiring the recommended inside and
outside antenna separation optimizes coverage significantly. Panel antenna can be
vertically installed 6 ft. under outside antenna with the booster at full dB gain. Inside
panel antenna should face away from outside antenna. If panel antenna faces outside
antenna, the booster will oscillate and go into Auto Shutdown.
Required Between
Outside and Inside Antenna
antenna separation
•
50dB 8-10 ft. separation
•
47dB 5-7 ft. separation
•
44dB 3-4 ft. separation
•
40dB 1-2 ft. separation
Adjust dB Gain according to table below if you cannot achieve maximum separation.
