The Portable Ka-Band VSAT RX/TX Antenna is designed for satellite communication applications where mobility, compact dimensions, and Ka-band operation are required. It uses a fiberglass reflector and is available with 0.65 m or 0.62 m reflector diameter. The specified RX range is 18.2-22.4 GHz and the TX range is 28.0-32.0 GHz.
Depending on the reflector version, gain is 40.0/44.0 dB or 39.6/43.5 dB for RX/TX, while weight is 10 kg or 8 kg. The antenna uses an EL/AZ mounting suspension, supports elevation adjustment from 0° to 50° and azimuth adjustment up to 150°, operates at wind speeds up to 20 m/s, and is rated for -45 to +50 °C in satellite use.
Detailed Description
The Portable Ka-Band VSAT RX/TX Antenna is designed for small satellite stations and portable SAT communication applications. Its compact construction and fiberglass reflector make it suitable for applications where the antenna must combine portability with defined Ka-band receive and transmit characteristics.
The antenna operates in separate receive and transmit frequency ranges: 18.2-22.4 GHz for RX and 28.0-32.0 GHz for TX. Two reflector configurations are specified — 0.65 m and 0.62 m – with corresponding differences in gain, aperture, G/T, F/D ratio, first side lobe level, and weight.
For the 0.65 m reflector version, the specified aperture is 0.33 m², RX gain is 40.0 dB, TX gain is 44.0 dB, and weight is 10 kg. For the more compact 0.62 m reflector version, aperture is 0.30 m², RX gain is 39.6 dB, TX gain is 43.5 dB, and weight is 8 kg.
The antenna uses an EL/AZ mounting suspension for pointing. The specified elevation range is 0-50°, while the azimuth range is 150° (60+90). It is rated for operation at wind speeds up to 20 m/s and within an operating temperature range of -45 to +50 °C.

Its specified 8-10 kg weight, EL/AZ pointing arrangement, operating wind speed of 20 m/s, and -45 to +50 °C temperature range are relevant for portable satellite communication installations.
Compatibility of the Portable Ka-Band VSAT RX/TX Antenna 18.2-22.4 GHz RX / 28-32 GHz TX
The antenna is intended for Ka-band SAT and VSAT systems operating at 18.2-22.4 GHz RX and 28.0-32.0 GHz TX. Integration should take into account the selected 0.65 m or 0.62 m reflector configuration, its corresponding gain and G/T values, and the required EL/AZ pointing arrangement.
How It Works ❓
- Ka-band signal reception.
In RX operation, the antenna works within the specified 18.2-22.4 GHz frequency range, with gain of 40.0 dB or 39.6 dB depending on the reflector configuration.
- Ka-band signal transmission.
For TX operation, the specified frequency range is 28.0-32.0 GHz, with gain of 44.0 dB for the 0.65 m version and 43.5 dB for the 0.62 m version.
- EL/AZ pointing.
The antenna is positioned toward the required satellite direction using its elevation and azimuth mounting suspension. Elevation adjustment is 0-50°, and the specified azimuth range is 150° (60+90).
- Two reflector configurations.
The 0.65 m and 0.62 m versions provide slightly different aperture, gain, G/T, F/D, side-lobe, and weight characteristics while operating within the same specified RX/TX frequency ranges.
