- This active receiving antenna has been designed for professional use and special emphasis has been placed on obtaining a large dynamic range with excellent cross and intermodulation properties, a low noise figure and a secure protection against RF-overload and violent nearby discharges.
- The AAC 1/... can be used either where superb listening quality is required or where a high RF-density environment exists, as for instance in connection with MF and HF duplex operation onboard ships, where nearby transmitting antennas may cause excessive field strengths. For complete safety the antenna should, however, not be mounted closer than 15 metres from transmitting antennas.
- The antenna consists of a high-capacitance glass fibre antenna element and an amplifier built into the antenna mount. The amplifier provides the necessary impedance matching between the high-impedance antenna element and the 50 Ω downlead cable over an extremely wide bandwidth.
- The necessary supply voltage (12 – 15 V DC) for the amplifier is delivered through the downlead coaxial cable from the junction box with mains power supply, type JB 230 (230 VAC) or JB 115 (115 VAC), which separates DC and RF-signals. Up to 200 m of RG 213/U coaxial cable can be used between antenna and junction box with only minor degrading effects.
- The earthing wire (see drawing) ensures a low loss connection to ground for RF-signals, and thereby also prevents noise pick-up from the ship’s installations running on the outside of the coaxial cable. As the earthing wire is AC-coupled, electrolytic corrosion is effectively prevented.
- By careful choice of materials, the AAC 1/... is designed to withstand the roughest of climate conditions, ensuring many years of trouble-free service.
- Extended amplifier frequency range makes it possible also to receive FM-radio (88 – 108 MHz).
