Material / Radome
Drawn copper tube / PC sleeve
Designed for router / dtu / gateway, the AW-CTB0827-2 is a 0.7-2.7 GHz internal spring / copper-tube antenna rated at 2 dBi. Its linear polarization and tuned matching network keep return loss low across the full operating band.
Radiation Pattern and Gain
As an omnidirectional radiator, it provides a full 360 degree azimuth pattern with an approximate 80 degree elevation beamwidth, distributing energy evenly around the mast. The rated gain of 2 dBi is referenced to an isotropic radiator.
Mechanical and Electrical Specifications
Mechanically, the AW-CTB0827-2 measures 68 x 8 x 8 mm and is housed in a Drawn copper tube / PC sleeve. The standard interface is a IPEX MHF (U.FL) connector, with a nominal impedance of 50 ohms and a typical VSWR of 2.5:1 or better. The element withstands up to 2 W of input power.
Installation Guidance
The recommended installation is embedded / internal. For best results, mount the antenna with clear line of sight to the served area and bond all outdoor hardware to a proper grounding system.
Typical Applications
Router / DTU / Gateway
IoT / M2M
Embedded Module

Frequently Asked Questions
What is a internal spring / copper-tube antenna used for?
Helical spring and drawn copper-tube radiators soldered or clipped inside a product housing where no external whip is acceptable.
Is AW-CTB0827-2 suitable for router / dtu / gateway?
Yes. AW-CTB0827-2 is well matched to router / dtu / gateway deployments, where its radiation pattern and gain provide reliable coverage and link margin.
Can the connector on AW-CTB0827-2 be changed?
Yes. The default RF interface can be supplied as SMA, N-type, TNC, or other connectors on request, and custom cable assemblies are available. Specify your interface in the inquiry form.
What is the standard impedance and VSWR of AW-CTB0827-2?
The nominal impedance is 50 ohms with a typical VSWR of 1.5:1 or better across the operating band. A 75 ohm option can be quoted for broadcast applications.
