Multi system GPS satellite receiving antenna

  BGG39 is a set of GPS L1 & L2 and GLONASS G1 & G2 dual-band double system measurement antenna, can be widely used in geodesy, bridge construction, marine surveying, underwater topography measurement etc. The antenna using multi feedpoint design, ensure the antenna phase center and the geometric center of the coincidence, improve the accuracy of measurement. Built-in low noise amplifier module, through the multi-stage filter to eliminate interference signal ,ensure the normal work in harsh electromagnetic environment.

 Waterproof Operation Details:

Multi-System antenna installation, waterproof operation deatils:

       1.Fit hot-melt sleeve over the RG8 line;

       2.Connect the connector of the RG8 cable to the connector of the BGG39 receiving         antenna;

       3.Waterproof tape to seal the joint position, and then hot air gun to heat the tape blowing;

       4.The hot melt casing on the push support frame, and then heated with hot air gun, you can melt the waterproof tape into a protective film, play a role in water.
