The GSM1800 Monitoring Directional Antenna is designed for RF monitoring with spatial filtering in the 1710-1880 MHz frequency range. It provides a minimum gain of 16.9 dB, vertical polarization, VSWR up to 1.83, and a first side lobe level of -25 dB. The beamwidth is 9.5° in the horizontal plane and 53° in the vertical plane.
The antenna supports input/output power up to 20 W and uses an N-type connection. It is specified for operation from -20 to +50 °C and at 100% humidity at 20 °C. With a weight of 5 kg and a narrow horizontal beam, the antenna is intended for GSM1800 monitoring tasks where directional reception and reduced side-lobe response are important.
Detailed Description
The GSM1800 Monitoring Directional Antenna 1710-1880 MHz is intended for monitoring applications where spatial filtering, high gain, and a very low first side lobe level are important. The antenna operates across the specified 1710-1880 MHz frequency range and uses vertical polarization.
A key characteristic of this GSM1800 monitoring antenna is its combination of minimum 16.9 dB gain and a -25 dB first side lobe level. The radiation pattern is significantly narrower in the horizontal plane, where the specified beamwidth is 9.5°, while the beamwidth in the vertical plane is 53°. These directional characteristics are directly relevant to monitoring tasks that require spatial selectivity.
The maximum specified VSWR is 1.83, while gain non-uniformity is specified as 0.4. The antenna supports input/output power of up to 20 W and uses an N-type connection.
The antenna is also specified for operation under defined environmental conditions. Its operating temperature range is -20 to +50 °C, while the specified humidity is 100% at 20 °C. The antenna weight is 5 kg.

Applications
The 1710-1880 MHz directional antenna is primarily intended for GSM1800 monitoring with spatial filtering.
- GSM1800 signal monitoring.
The antenna can be used in monitoring systems operating across the specified 1710-1880 MHz frequency range.
- Monitoring with spatial filtering.
The combination of 9.5° horizontal beamwidth, 16.9 dB minimum gain, and a -25 dB first side lobe level makes spatially selective monitoring the key intended application of this antenna.
- Directional RF monitoring.
Its defined directional radiation pattern allows the antenna to be used where monitoring must be performed within a specific angular sector rather than with omnidirectional coverage.
Compatibility of the GSM1800 Monitoring Antenna
The antenna is intended for systems operating within 1710-1880 MHz, using vertical polarization and an N-type RF connection. Integration should also take into account the specified VSWR ≤1.83, 20 W maximum input/output power, radiation pattern, and system requirements.
How It Works ❓
- Directional signal reception or transmission.
The antenna operates within the 1710-1880 MHz range and forms a directional radiation pattern rather than omnidirectional coverage.
- Narrow horizontal radiation pattern.
The 9.5° horizontal beamwidth concentrates the antenna pattern within a relatively narrow angular sector.
- Spatial filtering through directional characteristics.
The combination of a narrow main beam and the specified -25 dB first side lobe supports monitoring tasks where spatial separation of signals is required.
- Vertical polarization.
The antenna operates with vertical polarization, with minimum specified gain of 16.9 dB and maximum VSWR of 1.83.
Why Choose the GSM1800 Monitoring Directional Antenna ❓
The GSM1800 Monitoring Directional Antenna combines 1710-1880 MHz coverage, minimum 16.9 dB gain, a narrow 9.5° horizontal beamwidth, and a very low -25 dB first side lobe level. These characteristics make it particularly suitable for monitoring with spatial filtering, while vertical polarization, up to 20 W input/output power, an N-type connection, and operation from -20 to +50 °C provide clearly defined parameters for integration into monitoring systems.
