Active Receiving Antenna for 10 kHz - 110 MHz
DESCRIPTION
This active 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 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 noise fields running on the
outside of the coaxial cable. As the earthing wire is AC-coupled, electrolytic
corrosion is effectively prevented.
The antenna is supplied with DC-power through the downlead 50 Ω coaxial cable
by means of the included 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 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 BCL 1-KA 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.

INSTALLATION DETAILS USING SM-MA MOUNTING BRACKET
MOUNTING ON FLAT SURFACES
APPLICATION INFORMATION
The BCL 1-KA active receiving antenna is especially suitable for receiving of
broadcast radio stations in the long wave, medium wave, short wave and FM (88 -108
MHz) radio bands.
However, as the whole frequency range from 10 kHz to 110 MHz
is covered, the BCL 1-KA is also suitable as general purpose receiving antenna
throughout the whole range.
Several advantages can be gained by using an active antenna instead of an ordinary
wire antenna, especially in the lower frequency ranges. Firstly, the small physical size
makes the active antenna much easier to install. Secondly, a wire antenna requires a
matching unit which typically has narrow bandwidth, making retuning necessary when
changing listening frequency.
The active wideband antenna BCL 1-KA is optimized throughout the whole covered
frequency range. Thus, no tuning is required, making change of listening frequency
much easier.
Considering that the active antenna yields signal to noise ratios and signal strengths
normally only obtainable with much longer wire antennas, the BCL 1-KA makes a good
choice, especially also with respect to economy.
