Description

The SureCall SC-622CBM is a ceiling-mounted indoor antenna built specifically for C-band 5G systems. It’s designed to distribute boosted signal evenly in all directions, making it ideal for wide open indoor areas like office floors, hallways, or shared workspaces.

This antenna supports true MIMO performance with both vertical and horizontal polarization, which helps maintain fast, stable 5G connectivity when paired with a compatible SureCall C-band signal booster. It operates across the 3300 to 4000 MHz range, covering the key frequencies used by many private 5G and enterprise deployments.

Installation is straightforward for anyone familiar with drop ceilings or drywall mounts. It includes a threaded nut and mounting hardware to secure the antenna from above, and it connects to your system using standard SC-400 coax cable with an N-Female (50 ohm) connector.

If you’re setting up a SureCall C-band booster system and need reliable indoor coverage with support for high-speed data, this is the antenna designed for the job.

Frequencies Boosted: 3300 to 4000 MHz

Carriers: Compatible with U.S.-based 5G systems operating in C-band, including many private and enterprise networks

Note: This antenna is not designed for international use outside North America due to different frequency allocations

Installation

Basic steps:

  1. Drill a hole in the ceiling between 1.0 and 1.2 inches wide
  2. Feed the antenna cable through the hole
  3. From above the ceiling, thread the plastic fixing nut onto the antenna to secure it
  4. Tighten the nut and connect the antenna to your coax cable
  5. Run the cable back to your booster’s inside port

Installer tips:

  • Keep this antenna far away from any outdoor antenna or amplifier to avoid oscillation
  • Avoid placing the antenna near metal ductwork or other obstructions
  • For drop ceilings, make sure the ceiling tile can support the antenna or reinforce it from above
  • Don’t coil excess cable near the amplifier — run the full length cleanly

The ceiling thickness should not exceed 0.8 inches. If you're working in a space with thicker material or no crawlspace access, additional mounting hardware may be required.
