Supported Devices: All 5G phones, hotspots, and data-connected devices

Supported Networks: 5G only (on FCC-approved C-band frequencies)

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

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.
