Overview
This section describes the technical specifications and installation instructions for the Cisco Cellular 2-in-1 Vehicle Mount and Fixed Infrastructure Antenna, hereafter referred to as the antenna. The antenna is a two port antenna with two elements designed to cover the 698-960, 1448-1511, and 1710-2700 MHz cellular bands. The antenna can be mounted on the roof of a vehicle or fixed structure. The antenna meets or exceeds a variety of environmental ruggedization specifications for transportation applications.

Read the information in Safety Precautions before installing or replacing antennas. |
Antenna Features
The antenna features:
- Two cellular antenna elements within one radome
- Outdoor and transportation ready
- Roof mount installation
-
Dual cellular elements supporting 698-960, 1448-1511 and 1710-2700 MHz
- Omnidirectional, vertically polarized, MIMO
- Integrated 2 foot cables with TNC male connectors
- LTE elements are interchangeable, either one can be connected to Main or Aux.
The antenna may require RF extension cables. A shorter 2 foot cable length was selected on LTE WAN to allow you to optimize LTE WAN performance and wireless range. If you require a cable length longer than 2 foot with the antenna, then you would need to select RF extension cables of appropriate length and type.
Thicker RF cables, such as LMR-600, LMR-400, or LMR-240, result in lower loss, higher RF performance and longer range of wireless network than thinner cables such as LMR-195, LMR-200. The trade-off is that thicker cables are more difficult to bend and route.
For optimal performance, the length of thin cables needs to be kept as short as possible. For example, 2 foot and 10 foot lengths of LMR-195 cable at 2700 MHz frequency would have losses of 0.5dB and 2.3dB respectively. In this example at 2700 MHz the area covered by the wireless system with the 10 foot cable is reduced by 34% compared to 2 foot cable. Radius of communication is degraded by 20% in 10 foot vs 2 foot case.
Note |
Loss with the 17 foot GPS cable is compensated by the gain of the active GPS antenna and has little impact on GPS performance. |
