Overview
The A.80.A.101111 is a dome-style multi-band GPS antenna from the Bolt A.80 series, manufactured by Taoglas Limited. It supports L1 and L2 frequency bands with center frequencies of 1.575 GHz and 1.2276 GHz respectively. The unit features right-hand circular polarization and a 50-ohm input impedance. It includes a 1-meter RG-174 cable terminated with an SMA male connector. Physical dimensions are 94.3 mm in diameter and 25.4 mm in height.
Feature Summary
- Supports dual-band GPS L1 and L2 operations for enhanced positioning accuracy
- Features a low-profile, vandal-resistant dome design suitable for permanent mounting
- Constructed with UV-resistant housing and IP67 rated enclosure for environmental durability
Applications
- GPS navigation systems requiring high precision
- Fleet tracking and telematics applications
- Geospatial data collection equipment
- Marine and aviation navigation devices
Procurement Notes
Verify that the required cable length matches the integrated 1-meter RG-174 specification to avoid additional cabling needs. Confirm that the SMA male connector interface is compatible with the receiving equipment's port. Ensure the installation environment allows for the specified physical footprint and provides line-of-sight visibility for optimal signal reception.
Selection Notes
Select this model when dual-band L1/L2 performance is necessary for improved accuracy in challenging environments. The integrated cable simplifies assembly compared to bare antenna modules. Consider the permanent mount requirement as it is not designed for temporary or internal PCB integration. Verify that the SMA connector type aligns with existing system interfaces.
Part Context
This component belongs to the Bolt A.80 series of GPS antennas, which are engineered for robust outdoor and mobile applications. The series emphasizes durability and consistent performance across various global positioning standards. It serves as a specialized solution for users requiring reliable satellite signal acquisition in demanding operational conditions.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Users seeking alternatives should consult manufacturer catalogs for comparable dome-style multi-band GPS antennas with similar frequency support and connector types.
