Multi-band 7.3m Earth Station Antenna
Newstar's 7.3m satellite antenna is suitable for C, Ku, and other multi-bands, meeting FCC and ITU-RS-580 requirements. The earth station features a reflector design with precision-formed panels, contoured radiating lines, and machined hub assemblies. It features an innovative feed and sub-reflector design for high gain, low noise temperature, high antenna efficiency, and excellent noise and microwave interference rejection.
The large center wheel provides ample space for equipment installation. The reflector is supported by a galvanized main column base that provides the required stiffness for pointing and tracking accuracy. The base is designed for full track arc coverage and easily adapts to ground or roof installations.

FAQ for Buying 7.3m Satellite Dish
Q1. Can you give me discount price?
A: Due to satellite communication products are not the common products, so the discount is relative speaking. It's not big quantity that can obtain big discount. The prior issue is to ensure antenna's every specification and usage!
Q2. How can I get a sample?
A: For our products are industrial type antenna, the cost is relative high, so customer need to pay for the sample and undertake freight yourselves.
Q3. How can you deal with after-sale service?
A: Industial type satellite antenna is different from other products. For earth station type antenna that sizeS4. 5m, we usualy provide on-line guidance or antenna user manual to help customers to install antennaa; the earth station type antennas that size 24.5m, we can send engineer to go to customer's site training and helping the antenna users to intall & debug antenna system. We provide satellite communication integrated system training for customers.
Q4. What is payment term?
A: Generally, we prefer TT. However, it is open for discussion.
Q5. What is the production's lead time?
A: 1) If we have stock of your requested products, we will arrange shippment after receiving the negotiated payment;
