Cisco 4G/3G Omnidirectional Dipole Antenna (4G-LTE-ANTM-D)
Figure 7 Azimuth Cut (PCS) for Cisco 4G-LTE-ANTM-D
System Requirements
The Cisco 4G/3G omnidirectional dipole antenna is designed to be used with any Cisco 4G and Cisco 3G wireless ISRs G2 and
EHWICs with a TNC antenna connector. The threads on this connector must comply with ANSI 7/16-28 UNEF 2B thread
specification. The antenna is designed to be used only indoors.
Installation Notes
This antenna is designed to be mounted directly to any Cisco 4G and Cisco 3G wireless ISR and EHWIC with a TNC connector
by simply threading it onto the mating connector. Mount and deploy the antenna at the 0-degree position, 45-degree position,
or the 90-degree position, and then change that position at will. The rotation of the antenna into the proper position can take
place while the antenna is still loose on the mating connector. No software is required for this installation.
Caution: Do not install this antenna in an outdoor environment.
In addition to the antenna orientation, the installation location of the wireless EHWIC plays a significant role in determining overall
network performance with respect to all the wireless clients. Clients at the farthest coverage points might have 10 to 50 percent
of the bandwidth available to clients close to the antenna. Wireless network coverage in one area or location might need to be
lowered to improve the performance for clients in other areas or locations.
Because antennas both transmit and receive radio signals, their performance can be adversely affected by the surrounding
environment, including physical obstructions or radio frequency (RF) interference.
