• T-Mobile • US Cellular The A-9 may be used with a wide variety of cellular technologies including, but not limited to LTE, HSPA/HSPA+, UMTS, EV-DO, GSM, and CDMA. 1.2. MIMO (Multip le-Input an d Mult iple-Outp ut) When used with 4G/LTE or other high bandwidth devices, two A-9 antennas should be used per transmitter with each A-9 mounted a minimum of 17 inches apart (based on single wavelength separation at 700 MHz) to meet MIMO requirements. -

2. Vehicle Installation Antenna placement is critical to achieving optimal RF (radio-frequency) performance. When planning vehicle installations, the following considerations should be made: • Mount antennas as high as possible on the vehicle, away from other antennas and with minimal obstruction on all sides. -
Page 7: Antenna Placement
2.1. Antenna Placement Optimal placement is along the centerline of the roof (Figure 1) or in parallel columns down the length of the vehicle (Figure 2), in a position resulting in the shortest cable length possible. Maintain at least 17” separation between antennas. -
Page 8: Coax Cable Lengths
Use the shortest length allowing enough distance for service loops at both the antenna and modem/radio. Low-loss feed cables may be obtained from Atlas Labs at various lengths, enabling installers to minimize cable runs without the necessity of specialty crimping tools. -
Page 9: Ground Plane
2.2. Ground P lane Transmitting antennas require an electrically conductive ground plane to allow proper signal propagation. Typically the vehicle’s metal frame functions as the ground plane, however some vehicles such as RVs, buses, and ambulances with fiberglass roofs will need a separate ground plane plate.

3. Antenna Mounting The A-9 is a through-hole antenna, suitable for mounting on surfaces up to 3/8” thick. To install the A-9, perform the following: 1. Select appropriate position on vehicle roof ensuring clearance from obstructions and adequate distance from other antennas. Verify roof underside is clear of wires, cables, support posts, or other obstructions. -
