Product Description

Product Description

MULTI-STAR MULTI-FREQUENCY SPIRAL ANTENNA
PN:  GL-DY7038V11

GL-DY7038V11  is a multi-star and multi-frequency active spiral antenna, designed with multi-arm spiral technology, supporting compass B2 and tri-band satellite navigation signal reception for GPS, GLONASS, and GALILEO systems. It can meet the needs of multi-system compatibility and high-precision measurement, and can be widely used in portable equipment, UAVs, and other high-precision guidance position occasions, accepting user customization.

Technical Characteristics

Multi-arm helix technology is used to ensure right-handed circular polarization and phase center performance, reducing the impact of measurement errors.

An antenna unit using the air medium has the characteristics of high gain, small gain roll down, and low elevation satellite signal reception is good, to ensure that, in some of the more serious occasions can still be normal star.

3 protective covers for the antenna for long-term work in the field.

FAQ

Q: Main install spots for wall - mounted antennas?
A: Indoor corridors, meeting - room walls, malls, hotel lobbies/rooms, school classrooms/libraries. Pick spots for best coverage.

Q: How do wall - mounted antennas boost signal?
A: They receive/send signals better, direct signals to weak - coverage areas, reduce dead zones and interference for better strength/stability.

Q: Wall - mounted antennas work with diff wireless systems?
A: Usually yes, for Wi - Fi, 4G/5G, etc. Check specs on freq bands and connectors for compatibility.

Q: Factors for choosing wall - mounted antennas?
A: Wireless system freq band, antenna gain (affects coverage), radiation pattern (omni/directional), size/appearance for aesthetics.

Q: Can wall - mounted antennas be used outside?
A: Usually indoor - use. Outdoor - rated ones exist to handle harsh conditions.
