2J0819-C708N

Overview

The 2J0819-C708N is a GLADIUS series outdoor whip antenna designed for ISM, ERMES, and VHF applications. It operates within a frequency range of 169.4 MHz to 169.8 MHz with a 50 Ohm impedance. The antenna features linear polarization, an omnidirectional radiation pattern, and a maximum power rating of 25 W. Its physical dimensions are Ø13.2 mm in diameter by 70.4 mm in length, equipped with an SMA male connector mount.

Feature Summary

Omnidirectional radiation pattern for consistent signal coverage
Linear polarization optimized for specific protocol requirements
Whip mechanical form factor suitable for compact mounting

Applications

Smart metering networks
ERMES emergency radio systems
VHF communication links

Procurement Notes

Verify the specific ordering suffix and connector type against the official datasheet before purchase. Confirm regional availability as distribution status may vary. Ensure the selected variant matches the required frequency band and mounting style for the intended installation environment.

Selection Notes

Select this model when a dedicated VHF or ERMES solution is required. The narrow bandwidth suits fixed-frequency protocols. Consider the whip form factor for space-constrained installations where low-profile mounting is necessary.

Part Context

This component belongs to the GLADIUS product line from 2J Antennas. It is categorized under outdoor antennas and ISM/VHF types. The series focuses on specialized communication protocols requiring reliable vertical polarization.
