Product Description:
Ø Using multi-feed point design and completely symmetrical antenna structure, the phase center and geometric center coincide with each other, reducing the impact of the antenna on survey errors.
Ø High gain, wide beam, and good signal reception at low elevation angles, ensuring that satellites can still be collected normally in some severely obscured situations.
Ø Three channels of reception are filtered and amplified respectively, with excellent anti-jam ability and anti-burning ability of more than 10W.
Ø When the power amplifier is turned on, the two low-noise amplifiers should work normally and not be affected by emissions.
Ø Transmission output is greater than 40dBm, with good stability and efficiency.
Ø Power supply and four RF signals are input or output from one interface to facilitate connection with the host.
Ø All materials are independently controllable and 100% domestically produced.
Ø Dustproof and waterproof grade, meeting IP67.
Ø The radome is sturdy and has complex marine environment characteristics such as resistance to bird pecks, resistance to ultraviolet rays, resistance to sun exposure, and resistance to sudden temperature changes.
