NAVTEX Tri-Band Active Antenna – Mounting Instructions (Model 16201-XXX)
Proper installation of the NAVTEX Tri-Band Active Antenna (NAV3 – SCAN Antenna) ensures optimal performance and long-term reliability in all marine environments. Follow the instructions below carefully to achieve the best signal reception and to maintain antenna integrity.
Installation Guidelines
1- Mounting Location:
- Install the antenna at least 1 meter away from any obstruction such as masts, funnels, or radar domes.
- Keep it as far away as possible from any transmitting antennas to avoid interference.
- Do not position the antenna near halogen lamps or strong light sources, which may cause electrical noise.
2- Mounting Method:
- Attach the antenna to a 1″ threaded pole (G1″-11 thread) using the supplied revolving nut.
- The antenna body is electrically isolated from the mounting pole to prevent galvanic corrosion.
- Grounding:
- For proper function, the antenna must be RF-grounded using the supplied earth cable.
- This connection ensures galvanic isolation between the coaxial cable shield and the ship’s earth.
3- Waterproofing:
- Protect both the antenna connector and the earth wire junction from water ingress using self-vulcanizing tape or equivalent marine-grade sealing material.
4- Power Supply:
- Power the antenna through the down-lead coaxial cable using a stable 8–12 VDC power source.
- Ensure that the power supply is properly regulated and protected against surges.
Important Notes
- Avoid physical strain or sharp bends on the coaxial cable.
- Inspect connections periodically to ensure corrosion-free contact.
- Proper grounding and sealing are essential for long-term reliability and NAVTEX reception stability.
