Description
Fixed Antenna
The 1.8m aperture antennas panels are base coated with yellow strontium and face coated with polyurethane which is good performance for chemical, biology and nuclear protection. The steel structure is treated by sand blasting and zinc spraying, and then base coated with yellow strontium and face coated with polyurethane.
Thanks to the application of our advanced laser cutting technology and the good technical cooperation with the 54th Research Institute, my company has formed a full products range of antenna. From the minimum 0.8M diameter home TV antenna to the astronomical detection antenna with 100 meters above diameter, from normal plate shaped satellite antenna to detecting radar antenna ,our products can match the most buyers demands .Our products are of top rank quality and the price is absolutely competitive. Compared with European or American competitor, my product’s performance is similar, maybe more advanced in some respects, and the price will give you a surprise. So, do not hesitate to contact our sales department directly, you will get more surprises.
