BONITO recommends only "active antennas", if no possibility exists to use the Backstay or a long wire antenna. We tested many antennas and we found out that the BCL1 KA from Procom is a good compromise. The BCL1KA antenna is designed to withstand the roughest of weather and climate conditions and it is perfectly suited also for marine purposes.
This receiving antenna consists of a high-capacitance antenna element combined with an amplifier which is built into the antenna mount. The amplifier provides excellent impedance matching between the high-impedance antenna element and the 50 downlead cable over an extremely wide bandwidth. The amplifier is supplied with DC-power through the downlead 50 Ohms coaxial cable by means of the supplied junction box which can be mounted in close vicinity to the receiving station. The junction box separates DC and RF-signals and can advantageously be fed from the same 12 V DC-power supply as the RX-station.
The sensitivity of the amplifier is optimized so that noise generated in the antenna and the receiver is always less than noise picked up by the antenna. The amplifier is protected against RF-overload and violent discharges and the large dynamic range ensures excellent cross and intermodulation properties.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.
50cm FME-cable and an FME-UHF connector is included for connecting the box to the receiver as well as an FME crimp connector for the downlead cable (RG 58).
You still need coaxial cable from the antenna to the Junction box. Usually 10 meters are long enough on most of the boats. We offer but different cable lengths to eg mounting the mast. You can order the desired length directly with your order. The cables are all crimed on bith sides and comes with BNC or PL259 plug for your receiver.
