The SEA 1612C-ISOL is a 1.6 to 30 MHz 150 Watt Automatic Antenna Tuner weatherproof with Isolated Ground. It is designed for use with any 1.6 – 30 MHz, 150-watt transceiver. The 1612C accommodates most antenna configurations where tuning in the 4-meg and under bands is difficult. For operation on 13.6 VDC negative ground.
The SEA 1612C-ISOL Automatic antenna coupler is designed for use with SEA 235, SEA 235R, SEA 235D, SEA 245 and SEA 245/24 plus many more.
Designed and produced in the USA by SEA, an industry leader in high technology communications equipment, the SEA 1612C-ISOL automatic MF/HF tuner combines the sophistication of advanced microprocessor techniques with high order practicality and operational reliability. The SEA 1612C-ISOL is housed in a weatherproof molded case designed to withstand rugged environmental conditions encountered aboard ship while mounted on the external weather decks.
An automatic tuner/coupler is a necessity with modern multi-channel Marine MF/HF SSB transceivers like the SEA 235 and SEA 245G to obtain an efficient match between the antenna and radio. Also excellent for land mobile installations, the SEA 1612C-ISOL is capable of tuning a vertical MF/HF antenna whip over a frequency range of 1.5 to 30 MHz.
The SEA 1612C-ISOL is a versatile, fully automatic microprocessor-based antenna tuner. Upon the first receiver impulse, the transceiver initiates a rapid microprocessor controlled search/match procedure that determines antenna characteristics and inter-connects the proper elements for optimum match and power transfer.
An internal microprocessor in the SEA 1612C-ISOL has a “learning” capability that remembers which network constants were set in for a particular frequency. The SEA 1612C-ISOL will continuously monitor and make adjustments automatically to any changes in the antenna system.
The SEA 1612C-ISOL also includes the following features:
- Duplex Mode makes use of a special control algorithm that senses the RECEIVE mode of duplex channels.
- Tune Lockout feature is useful when two or more transmitters are co-located.
- Demand Tune function allows the user to force the antenna tuner to re-tune on demand.
- The SEA 1612C-ISOL is also available with an antenna grounding relay.
