Cisco 4G Indoor/Outdoor Active GPS Antenna (GPS-ACT-ANTM-SMA)
First Published: July 22, 2013
The Cisco 4G indoor/outdoor, active GPS antenna (GPS-ACT-ANTM-SMA) can be physicaly connected to the Cisco 819 Integrated Services Routers (ISRs) and Cisco 4G Enhanced High-Speed WAN Interface Cards (EHWICs) to receive GPS broadcasts from satellites.
Specifications
Table 1 Specifications for the Cisco GPS-ACT-ANTM-SMA Antenna
VSWR1
Antenna-LNA1-BPF1-LNA2-cable-SMA(m) connector.
Due to a topology without front end filter immediately following the antenna, the antenna has the benefit of a lower noise figure, but may not be suitable for collocation with a high power wireless transceiver.
RHCP2
3 stainless-steel screws that are self-drilling pan head #2 Phillips.

Installation Guidelines for the Cisco 4G Active GPS Antenna
- The antenna must be placed so that the radome has a clear site to just above the horizon and a clear view of the horizon.
- Antenna performance can be adversely affected by the surrounding environment such as physical obstructions or radio frequency (RF) interference.
- Avoid mounting the antenna next to a column or vertical support that could create a shadow zone and reduce the coverage area.
- Keep the antenna away from reflective metal objects that block cellular signal and make reception poor, such as heating and air conditioning ducts, large ceiling trusses, building superstructures, and major power cabling runs. If necessary, use an extension cable to relocate the antenna away from these obstructions.
- If installing the antenna indoors, make sure it is near a window.
Note The Cisco logo and product ID are printed onto the GPS-ACT-ANTM-SMA antenna radome. Position the antenna as shown in the Figure 1.
Mounting the Cisco 4G Active GPS Antenna Without Bracket
Attach the antenna radome to any magnetic metal surface or stick the antenna radome onto a non-metalic surface using the sticky back.
Mounting the Cisco 4G Active GPS Antenna With the Bracket
Step 1 Use the supplied metal bracket, screws and wall anchors (if necessary) to mount the antenna to a wall, as shown in Figure 2.
Step 2 Insert the cable through the hole on top of the bracket and seat the antenna radome on the bracket as shown in Figure 2.
Attaching the Cisco 4G Active GPS Antenna Cable to the Device
For the Cisco 819 ISR (Figure 3) and 4G EHWIC module (Figure 4), unscrew the cap-screw on the GPS mating connector. Next, tightly screw the antenna cable SMA male connector to the GPS mating connector.
