Product Description
KA Band Microwwave Antenna
Gospell Ka-band antenna feeder devices are a new technology that has a number of advantages over the more established Ku band and C-band.
Ka-band is far more versatile solution and offers numerous benefits over existing antenna solutions. In particular, it can provide the following:
Main Features:
- Where satellite communication on the move is needed as Ka-band can be portable as demonstrated with our portable satellite antenna-feeder.
- It can quickly be put together and dismantled.
- It provides higher bandwidth.
- It has lower data transmission costs.
- Depending on which model is chosen, both receive and transmit are supported.
- The satellite antenna-feeder device can be used in VSAT terminal applications, combined with some existing technology.
- The Microwave antenna-feeder device can be used in terrestrial microwave transmission systems, where point-to-point is need.
Gospell currently offers three different models in its Ka-band antenna-feeder range:
- A 0.6m/0.75m single reflector unit. This unit is shown mounted on the tripod.
- A 0.7m dual-reflector antenna unit.
- A microwave antenna which can be available in sizes from 0.3m to 1.8m in single polarised as well as dual polarised versions. This unit is shown mounted above.
