Mounting The Vml750 Antennas - Motorola VML750 Installation Manual

Mounting the VML750 Antennas

NOTICE: before installing the antenna cables, add an identical label on both ends of each cable to ensure
correct connection between the antenna and its related connector on the VML750 back panel.
The VML750 antenna is used to enhance the reception capability in poor reception areas and support Multiple
Input Multiple Output (MIMO) modes for LTE.
Two identical Antennas are used; one for WWAN2 Main and one for WWAN2 div. The Antennas can be provided
with 12-ft (P/N: FTN6070A) or 17-ft (P/N: FTN0073A) coaxial cable.
To complete the public network installation, base with cup antenna is used for WiFi connectivity on WWAN1
WiFi/Div and GPS reception (P/N: AN000036A01). The antenna is constructed of three Antennas:
• Internal antenna - for WiFi (to be connected to WWAN1 diversity)
• External antenna – Whip connected to Main1 (for use only with B14)
• GPS active antenna (to be connected to GPS port)
IMPORTANT:
Use the following guidelines for antenna mounting to ensure best performance and avoid signal
reduction and interference:
1. When installing antenna Main 1 or Main 2 or Div 2, keep a clear radius of more than 20 cm (8")
from other Antennas.
2. When installing antenna Main 1 or Main 2 or Div 2, keep a distance of more than 20 cm (8") from
the front edge of the car roof. Install the Antennas in a distance of about 10 cm (4") from the
center line crossing the length of the car.
3. Keep a clear distance of more than 30 cm (11.8") between antenna Div. 2 and Main 1.
4. Keep a clear distance of more than 30 cm (11.8") between antenna Div. 2 and Main 2.
5. Keep a clear distance of more than 100 cm (39.4") between antenna Div. 1 and Main 1.
6. Keep a clear distance of more than 100 cm (39.4") between antenna Div. 1 and Main 2.
7. When installing antenna Div. 2 at the center line of the roof, keep a distance of more than 20 cm
(8") from the rear edge of the car roof.
IMPORTANT: To assure optimum performance and compliance with RF Energy Safety standards,
these antenna installation guidelines and instructions are limited to metal-body vehicles with
appropriate ground planes and take into account the potential exposure of back seat passengers
and bystanders outside the vehicle.
