Request a quoteProduct overview
A cylindrical antenna for 1.2–1.3 GHz communication links, with RHCP, 50 Ω impedance and an SMA interface. A 120 mm cable configuration and connector/cable customization are available. Frequency-by-frequency installed gain, efficiency and reflection references support selection for the actual installation.
Features
- Covers 1200–1300 MHz with a right-hand circularly polarized configuration.
- The cylindrical assembly uses FPC, PCB and coaxial cable with a 50 Ω interface.
- An SMA connector and 120 mm cable configuration is available; connector and cable length can be adapted to the project.

Selection and application notes
The gain, efficiency, S11 and VSWR reference tables are installed-configuration measurement records. Values vary with frequency and installation and are not performance guarantees for other installations or configurations.
FPC and PCB dimensions describe internal components, not the overall antenna assembly. Select the configuration according to installation space, cable routing and interface requirements.
The bulk-packaging reference is a resealable bag of 50 pieces. Actual packaging and delivered configuration follow the order, without changing the usual one-piece MOQ support.
The photograph shows a cylindrical antenna with SMA. Delivered appearance, cable length and interface follow the configuration drawing and quotation.
Ordering and customization
Typical MOQ is 1 piece, with samples in about 2 weeks and volume delivery in about 4 weeks. Connector, cable-length and application customization are available; specifications and delivery follow the requirement review and formal quotation.
