Key Features

  • WORKS ON ANY CELLULAR NETWORK (4G / LTE / GSM) such as Verizon, AT&T, Sprint, T-Mobile and more. This is *NOT* a TV antenna
  • COMPATIBLE with Modems and Routers from CalAmp, Cisco, Cradlepoint, Digi, MoFi, Multi-Tech, Pepwave, Proxicast, Sierra and others
  • DUAL ANTENNA MIMO Design Improves Performance - Flexible Magnetic & Adhesive Mounting Options
  • 2.5 dBi OMNIDIRECTIONAL GAIN - Similar to standard 6" tall antennas
  • SUPER THIN - 0.6 inches High x 3.15 inches Diameter - SMA Male Connector with 6 ft Coax Pigtail - Perfect for Kiosks, Vending Machines, Control Panels, Ceilings and Covert Installations


This extremely low profile (< 0.6 inches tall) fixed mount omni-directional antenna provides up to 2.5 dBi of gain and works on all 3G & 4G cellular frequency bands worldwide (all CDMA, GSM, WCDMA/UMTS and LTE carriers).

Includes 3M adhesive pad and strong internal magnet for flexible mounting options. IP67 waterproof.

Similar in gain to rubber-duck style antennas often included with cellular modems, this antenna is designed for M2M applications such as vending machines, meter housings, equipment sheds, or other locations requiring an inconspicuous low-profile external antenna that can be placed in a more favorable location. Can also be vehicle mounted for buses, vans, trucks or other mobile installations.

Dual integrated SMA male plug connectors mate with SMA female jacks on MIMO capable modems, routers, etc.

This antenna performs best when installed on a horizontal metal surface of at least 8x8 inches.

The TS9 version of this antenna is part # ANT-122-M09.
