Indoor 900 MHz Antenna Kit
The EnGenius SN-UL-AK20L-IND is a new 900 MHz indoor external antenna supplied with 20 metres of LMR-400 cable. It presents a 50 Ω impedance and a gain range of 2.1 to 2.7 dBi with linear vertical polarisation. A reverse-thread N-type female connector is pre-fitted for direct attachment.
Ideal for Indoor Coverage Extension
This antenna suits installers who need to bring a 900 MHz signal inside a building while keeping cable loss low over a 20 metre run. It is not for outdoor mast mounting, for frequencies outside the 900 MHz band, or for systems that require a different connector type or impedance.
Gain and Cable Headroom
The 2.1 to 2.7 dBi gain provides modest signal improvement for typical indoor distances. The LMR-400 cable keeps attenuation minimal across the full 20 metre length, but longer runs or higher-gain requirements would need a different antenna or lower-loss feedline.

Questions about this item
Which connector must my gateway or access point provide to attach this antenna's pre-terminated cable?
The antenna cable ends in a reverse-thread N-type female connector, so the radio side needs a matching reverse-thread N-type male port.
Will the 20 m LMR-400 run introduce too much loss for a legacy 900 MHz radio I plan to keep?
LMR-400 is a low-loss cable; at 900 MHz the 20 m length keeps attenuation minimal, preserving the antenna's 2.1-2.7 dBi gain for older equipment.
How can I confirm the antenna is radiating properly once ceiling-mounted?
Measure received signal strength on a client device — consistent improvement matching the 2.1-2.7 dBi gain and vertical linear pattern indicates correct operation.
