RX 5000
Self-Supporting Wide-Band Receiving Whip Antenna for the
LF, MF and HF Bands.
DESCRIPTION
This antenna provides a very efficient means of establishing a universal,
wide-band 50 Ω receiving aerial system for the complete LF, MF and HF
bands in one unit.
The antenna consists of a high-capacitance, 5 m long glass fibre
antenna element with a frequency-compensated wide-band impedance
transformer mounted in the bottom end.
The transformer converts the widely varying antenna impedance to a
constant 50 Ω, making it possible to use length-independent, shielded,
standard RG 58 C/U or RG 213/U as downlead cable to the 50 Ω
receiver.
The antenna is protected against noise pick-up running on the outside of
the downlead cable, and it is protected against static by DC-grounding.
Moreover, the 50 Ω receiver and the matching transformer itself are
protected against RF overload and violent discharges by an air spark gap
(approx. 1 kV), a gas filled spark gap (90 V) and a resistance network.
To prevent electrolytical corrosion, the coaxial cable braid is only
capacitively coupled to the earth connection.
Installation is easily carried out by means of the two hot galvanized
mast clamps. The antenna has very small weight and minimum wind
surface, thereby requiring only a minimum of mast strength.
The glass fibre construction gives a stiff and self-supporting structure
with extremely good resistance against the corrosive marine
environment with UV-radiation, salt, exhaust gases and ice formation as
primary factors.
RX 5000 is a maintenance-free and very reliable construction.
