KODEN GA-08 GPS ANTENNA

The KODEN GA-08 is a rugged, high-sensitivity GPS antenna specifically designed for marine navigation systems. It provides fast and precise satellite signal acquisition for compatible Koden GPS navigators and chart plotters, ensuring reliable positioning in harsh offshore environments.

Technical Specification

GPS Reception Characteristics:

Receiving Frequency: 1575.42 MHz (L1 band, standard GPS frequency)
Receiving Channels: 18 channels parallel (allows for quick acquisition and tracking of multiple satellites simultaneously).
Receiving Code: C/A code
Sensitivity: Better than -130 dBm (at an elevation angle of 5° or over), indicating high sensitivity for weak signal acquisition.

Physical & Environmental:

Antenna Type: Passive GPS antenna (meaning it draws power from the connected GPS receiver/navigator).
Cable Length (Standard GA-08): 10 meters (approximately 33 feet)
- Variations exist:
  - GA-08L: 15 meters (approx. 49 feet) cable.
  - GA-08S: 0.5 meters (approx. 1.6 feet) cable (designed for use with an extension cable).
Connector Type: BNC connector (on the GA-08 and GA-08L), N-P connector (on the GA-08S).
Weight (without cable): 0.19 kg (0.42 lb)
Weight (GA-08 including 10m cable): 0.62 kg (1.4 lb)
Dimensions: While precise dimensions are not always listed independently, based on typical diagrams for Koden antennas, it’s a compact, dome-shaped antenna. Approximate diameter of the base is around 90-100mm.
Mounting: Typically designed for pole mount or surface mount.
Waterproofing: IPX6 (Protected against powerful jets of water), making it highly suitable for exposed marine environments.
Operating Temperature: -25°C to +55°C (-13°F to +131°F).
