BCL 1-KA
Active Receiving Antenna for 10 kHz - 110 MHz
DESCRIPTION
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 Ω downlead cable over an
extremely wide bandwidth.
The amplifier is supplied with DC-power through the downlead 50 Ω
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 DC-power supply as the receiver (if 12 V).
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.
The junction box is protected against accidental polarity reversal and it
is filtered to avoid interference pick-up.
The junction box is provided with FME-connectors for the antenna and
the receiver ports. 1 m 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).
The antenna is designed to withstand the roughest of weather and
climate conditions and it is perfectly suited also for marine purposes.
The BCL 1-KA is supplied with the "SM-MA" mast mounting bracket.
