The 4G-LTE-ANTM-D omnidirectional dipole antenna is designed for indoor use with Cisco 4G and Cisco 3G wireless Integrated Services Routers Generation 2 (ISRs G2) and Enhanced High-Speed WAN Interface Cards (EHWICs). The 4G-LTE-ANTM-D antenna is marked with a green band and the product ID (PID) to indicate that it supports 4G Long Term Evolution (LTE) networks. It has the following hardware features: - Articulating Joint—It can be rotated 360 degrees and is capable of maneuvering into three stop positions: 0 degrees, 45 degrees, and 90 degrees. - Male threaded Neill-Concelman (TNC) Connector—It lets you directly mount the antenna to any Cisco 4G and Cisco 3G wireless Integrated Services Router (ISR) EHWIC with a TNC connector (Figure 1). The threads on the connector must comply with the ANSI 7/16-28 UNEF 2B thread specification.
