PRE OWNED SAILOR TT-3020C SAILOR TT-3020C MARINE ANTENA

PRODUCT OVERVIEW

The Sailor TT-3005M is an omni-directional maritime antenna specifically engineered for the Sailor TT-3020C and TT-3022D transceivers. Known for being one of the smallest Inmarsat-C antennas in the world, it provides a stable satellite link even at low elevation angles (down to -15 degrees), which is critical for vessels operating in rough seas or high-latitude regions.

The unit is completely maintenance-free with no internal moving parts. Its rugged, hermetically sealed radome is designed to withstand the most extreme weather conditions, including heavy icing, high-intensity rainfall, and hurricane-force winds. The integrated design simplifies installation by using a single coaxial cable for power, satellite data, and GPS signals.

KEY FEATURES & APPLICATIONS

-- GMDSS Ready: Fully compliant with Inmarsat-C GMDSS specifications (CN114) for safety and distress communication in Sea Areas A1, A2, and A3.

-- Integrated GPS/SAT-C: Combines a high-sensitivity GPS element and a robust Inmarsat-C helical element, reducing the number of antennas required on the mast.

-- Smallest Footprint: Its compact size makes it the ideal choice for vessels with limited mast space or for quick replacement of older, bulkier antennas.

-- High Data Capacity: Approved for up to 32kb message size transmissions, allowing for graphics, pictures, and large data files.

-- Long Cable Support: Can be installed up to 100 meters away from the transceiver using high-quality low-loss coaxial cable (e.g., RG-214).

-- All-Weather Reliability: Designed to operate in high solar radiation and extreme precipitation (up to 100mm/hour) without loss of signal quality.

TYPICAL CONDITION (USED/REFURBISHED)

Refurbished TT-3005M units from the Alang/Bhavnagar shipyards are thoroughly tested for signal gain and power output. We check the internal LNA (Low Noise Amplifier) to ensure it meets the -23 dB/K G/T requirement for Inmarsat-C reception. Each unit is inspected for physical integrity of the radome seal and cleaned of any salt-air corrosion at the TNC connector to ensure a secure, moisture-free connection.
