Dolph Microwave as experienced manufactures of satcom antenna offering various type of satcom antenna to solve communication. An satcom antenna can be used for both transmitting and receiving signals from the satellite including GEO, LEO and MEO etc.. Based on function, it can be divided into Rx only and Tx/Rx type. Rx only of mainly for broadcast and Tx/Rx are mostly for communication and others. They can provide access to satellite communications even in harsh environments.
Dolph Microwave satcom antenna can be divided into 3 types including earth station antenna, flyaway(quick deploy) antenna and Motorized Quick Deploy Antenna. The frequency band are available in single band, dual band and multi band like C-band, Ku-band, Ka-band, X-band, S-band and also C&Ku, Ku&Ka and S&X dual band. Besides the standard diameter with standard frequency range. It can also be customized based on customer requirement. Any requirement, please inform at any time.

Antenna is an important part of satcom communication system as the antenna RF signal input and output channel. The performance of antenna and microwave waveguide components affect whole system performance. The distance between antenna and satellite is far. To assure the signal effective transmission, most of the earth station adopts parabolic antenna. All of Dolph Microwave offered antenna is parabolic antenna with features is high gain and better directivity.
Antenna sorts is distinguished with different basis. With the reflector quantity, it can be divided into dual reflector and single reflector antenna. For the feed method, it is prime focus antenna and offset antenna. For the band, it included single and multi band antenna etc.
1. Large coverage area and long communication distance
2. Multi-link capability
3. Wide frequency band, large communication capacity
4. Good communication quality and high reliability
5. Flexible communication
6. Various band covering with different satellites
LEO: Low Earth Orbit(orbit 700~1500 km above the Earth’s surface)
MEO: Medium Earth Orbit(orbit 10000~20000 km above the Earth's surface) perigee apogee
HEO: Highly Elliptical Earth Orbit (Degree 63.4 or 116.6 )
GEO: Geostationary Earth Orbit(35768 Km; Time period : 24 hrs)
