CLTM101 (UHF)

UHF Ceiling-Mount Antenna


The CLTM101 is a ceiling-mounted UHF antenna for in-building radio systems, providing omnidirectional 420–470 MHz coverage from a standard suspended-ceiling location.

Key Features

  • Delivers omnidirectional UHF coverage across 420–470 MHz.
  • Handles up to 60 W for compatible in-building radio systems.
  • Installs directly on metal drop-ceiling grids with included hardware.
  • Maintains operation across −40 °C to +80 °C environments.

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

Product Description

UHF Coverage Built for the Ceiling Grid.

The CLTM101 places one omnidirectional UHF element in a compact ceiling-mounted housing for in-building radio systems. Its single antenna location supports 420–470 MHz coverage while keeping the installation above the occupied space.

Purpose-Built UHF Coverage: The element provides unity gain across 420–470 MHz and handles up to 60 W for compatible UHF radios.

Omnidirectional Indoor Pattern: Signal is distributed around the ceiling location, supporting in-building radio coverage without aiming the antenna toward one direction.

Drop-Ceiling Integration: The included clamp attaches to a metal ceiling-tile grid, and the 5.50-inch-diameter housing keeps the installed profile compact.

Broad Operating Temperature: Operation from −40 °C to +80 °C accommodates a broad range of installation temperatures.

The CLTM101 provides a focused in-building UHF option when one ceiling-mounted radio connection is required.

Ideal Applications

  • In-building UHF radio systems
  • Distributed radio installations
  • Facilities with suspended ceilings
