Product Description:
Ø It has the ability of anti-rejection and anti-jam of four elements in the BDS B3 frequency band, and can also receive BDS B1 frequency band signals.
Ø The antenna adopts double feed point design, which has good circular polarization performance and good pattern consistency.
Ø The low-noise amplifier part adopts a pre-filtering scheme, which can effectively reject out-of-band strong jamming signals, avoid amplifier saturation, and improve system reliability.
Ø Ability to resist high-power continuous wave damage.
Ø Equipped with a breathing valve to ensure that the internal and external air pressure is balanced when the antenna is working.
Ø The metal bottom shell and radome are spray-painted, and the radome is made of high-quality materials with good weather resistance and anti-aging, suitable for long-term field work.
