Security Brands 16-ANTOMNI 4G LTE Omni Antenna Extension Kit, 25 Ft
The Security Brands 16-ANTOMNI is the longer 25 ft 4G LTE omnidirectional antenna extension kit used to support compatible Security Brands Ascent cellular access-control equipment. In gate and building-entry installations, cellular products often work best when the antenna is above or outside the cabinet rather than buried inside a metal enclosure or masonry column. This kit is intended for jobs where a short antenna extension is not enough and the antenna needs to be placed at a higher, clearer, or more exposed location. Correct selection is important because antenna kits need to match the cellular product, connection style, and desired cable run.
Typical applications include Ascent controller installations in metal gate operator cabinets, telephone entry pedestals, block columns, equipment rooms, guard shacks, and remote sites where the antenna must be moved away from shielding to improve cellular reliability.

Technician Note
Before mounting the antenna permanently, test cellular signal at the planned antenna location. Moving the antenna higher or outside of metal shielding usually helps more than simply adding cable length.
Before Ordering
- Confirm the Ascent product supports this antenna kit.
- Confirm the 25 ft cable length is appropriate for the final antenna location.
- Confirm the antenna can be mounted securely and away from moving gate parts.
- Confirm the cable route is protected from sharp edges, water entry, and pinch points.
- Confirm the site has usable cellular service at the antenna location.
Important Ordering Warnings
- This accessory improves antenna placement but does not guarantee cellular coverage in every location.
- Do not coil excess cable inside high-voltage compartments or moving operator areas.
- Follow the Ascent installation guide and use a qualified technician for cabinet modifications.
Professional Advisory
For access-control equipment tied into a powered gate operator, door operator, electric strike, or magnetic lock, installation and troubleshooting should be handled by a qualified access-control or gate technician. Do not bypass required safety devices, emergency-access requirements, or local code requirements during installation.
Product Questions and Answers
What is included with the 16-ANTOMNI kit?
The kit is commonly supplied with a 4G LTE omnidirectional antenna, 25 ft cable, and mounting hardware.
Is this the same as 16-ANTX-1?
No. The 16-ANTOMNI is the longer 25 ft omnidirectional antenna kit. The 16-ANTX-1 is the shorter 5 ft antenna extension kit.
Which products use this antenna kit?
It is used with compatible Security Brands Ascent cellular access-control installations where the antenna connection and site layout support it.
Can it fix poor signal inside a metal enclosure?
It can help by moving the antenna outside or above the enclosure, but the new antenna location still needs usable cellular signal.
Does it include a cellular controller?
No. This is only the antenna extension kit and does not include an Ascent controller or cellular service.
