C27S

Antennas RF Overview

The TE Connectivity C27S is a 29 MHz whip antenna designed for VHF applications. It operates within a frequency range of 26.75 MHz to 31 MHz and features a straight whip design with an NMO base mount. The antenna provides 0 dB gain and maintains a VSWR of 2. With a maximum height of 52.5 inches (133.35 cm), it is constructed as a DC grounded, base-loaded unit suitable for mobile radio installations requiring reliable signal transmission.

Antennas RF Feature Summary

• Straight whip antenna design optimized for VHF band operations
• NMO base mounting interface for secure vehicle installation
• DC grounded base-loaded construction for enhanced power handling
• Reduced ground plane requirements compared to standard base loaded antennas

Antennas RF Applications

• CB radio communications
• 10-meter amateur radio transmissions
• Mobile vehicle communication systems
• VHF marine or land mobile radio setups

Antennas RF Procurement Notes

Verify the specific datasheet version and physical dimensions against project requirements before ordering. Confirm that the NMO base mount compatibility matches the intended vehicle or platform. Ensure the operating frequency range aligns with local regulatory standards for CB and 10-meter bands. Check for any specific environmental ratings if the installation location is exposed to extreme conditions.

Antennas RF Selection Notes

Select this model when a robust, high-power capable antenna is needed for 27-30 MHz frequencies. The NMO base offers a secure, weather-resistant mounting solution for permanent vehicle installations. Consider the 52.5-inch length for clearance constraints. This antenna is suitable for users requiring less ground plane dependency than traditional designs while maintaining standard gain characteristics.

Antennas RF Part Context

The C27S belongs to the C27 series of mobile antennas from TE Connectivity. This series focuses on base-loaded whip antennas for VHF communications. The C27S specifically targets the 29 MHz center frequency, distinguishing it from other models in the lineup that may operate at different bands such as 47-50 MHz like the C47S.
