4.2m Ka Band LEO RXO Antenna


Online consulting:      

  • DESCRIPTION
  • TECHNICAL
  • SPECIFICATIONS

PR42X / Y-K model 4.2m antenna is designed for K-band LEO satellite communication. The antenna is in the form of dual shaped Ring-Focus antenna. The main reflector is divided into 12 panels, made with aluminum stretched panel. The feed horn is multi-mode corrugated horn. The feed is optional with TE21 mode mono-pulse auto tracking or program tracking plus step-tracking.


The antenna pedestal is in X / Y type. It is the key performing mechanism to achieve non-blind tracking in zenith. Each axis rotation range is ± 90˚, can cover the entire airspace, effectively avoid coiling and collector ring problem in Az/El structure. This structure is applicable for LEO satellite antenna tracking. The large-size final drive has high structural rigidity ensured the antenna pointing accuracy, tracking accuracy and rotation stability of the overall structure.


Probecom offer Remote satellite sensing antenna, Remote sensing data receiving system, Vechile mounting remote sensing station, Vechile carrier remote sensing station.


he main functions:

a) Have mono-pulse auto tracking, program tracking plus step-tracking, and external data guide tracking modes.

b) Have time offset adjustment and X, Y axis angle adjustment function in program tracking mode.

c) Have angle measurement data acquisition function in auto tracking mode;

d) Can be connected via a network interface or RS-232 serial interface with system monitoring computer, monitors the parameter configuration of antenna system, control and equipment status.
