Q1:Are you a factory or trading company?

A:We are a factory.

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 the freight yourselves.

Q3:How does your factory do regarding about quality control?

A:Quality is priority.The products will be checked many times before final packing.

Q4:What is the productions lead time?

A:1)If we have stock of your requested products,we will arrange shippment after receiving the negotiated payment.

2) If the requested products need production,will deliver the goods as per the negotiated date. 

Q5:How can you deal with after-sale service?

A:Industrial type satellite antenna is different from other products.For earth station antenna that size is 4.5m,we usually provide on-line guidance or antenna user manual to help customers to install antenna.For the earth station type antenna that size 4.5m,we can send engineer to go to customers site training and helping the antenna users to install&debug antenna system.We provide satellite communication integrated system training for customers.
