CLTM302 (1x or 2x 4G/LTE)

Configurable LTE Ceiling-Mount Antenna


The CLTM302 is a configurable ceiling-mounted LTE antenna for in-building and distributed antenna system installations, available with one cellular element or two elements for 2×2 MIMO.

Key Features

  • Adapts one ceiling platform to SISO or 2×2 MIMO requirements.
  • Covers low-band and higher-frequency LTE from each cellular element.
  • Distributes omnidirectional cellular coverage around the ceiling location.
  • Attaches directly to a metal drop-ceiling grid.

Customization: Cable type, cable length, and connectors can be configured for specific installation requirements.

Product Description

One Ceiling Platform. Two LTE Configurations.

The CLTM302 is a configurable ceiling-mounted LTE antenna for in-building and distributed antenna system installations. Available with one or two cellular elements, it allows the same ceiling-mount form factor to support either a single connection or a 2×2 MIMO system.

One Platform for SISO or MIMO: Choose one cellular element for SISO or two independently fed elements for 2×2 MIMO, matching the antenna configuration to the radio without changing the ceiling-mount platform.

Wideband LTE Connectivity: Each element covers 694–960 and 1710–3700 MHz, providing low-band and higher-frequency LTE connectivity from the same antenna.

Omnidirectional Indoor Coverage: The antenna distributes cellular coverage around the ceiling location without requiring directional alignment.

Simple Ceiling Integration: The supplied bracket or clamp attaches directly to a metal ceiling-tile grid for suspended-ceiling installations.

The CLTM302 can match SISO or 2×2 MIMO requirements without changing the mounting approach.

Ideal Applications

  • In-building LTE networks
  • Distributed antenna systems
  • SISO cellular installations
  • 2×2 MIMO cellular installations
  • Facilities with suspended ceilings
