The HF Dipole R&S HX002A1 can be connected directly to the HF
Transceivers R&S XK2100. For connection to other transceivers,
the Junction Unit R&S GX002A1 is available to provide power
supply and tuning control.
Brief description
The HF Dipole R&S HX002A1 provides good coverage over all distances. In contrast to rod antennas, it features high transmission
reliability especially over short and medium distances due to
NVIS radiation which eliminates the skip zone of vertical
antennas.
The antenna can easily be integrated into existing systems since
no control line is required. All the control signals and the ATU
supply are fed via the coaxial cable.

Naval HF Dipole R&S® HX002M1
Especially designed for shipboard
communication
Brief description
The Naval HF Dipole R&S HX002M1
enables optimum coverage over all
distance ranges. It is particularly advantageous for radiocommunication over
short and medium distances, since below
1000 km rod antennas cannot guarantee
sufficient transmission reliability because
of their skip zone.
The HF Dipole R&S HX002M1 provides
high-angle radiation (NVIS: near vertical
incident skywave) to ensure omnidirectional coverage at suitable frequencies,
i.e. between 2 MHz and 8 MHz. The
antenna operates below 2 MHz as a topfed monopole, thus ensuring omnidirectional coverage with ground waves in the
frequency range suitable for this purpose.
Type Index
The HF Dipole R&S HX002M1 is designed
for both transmission and reception. The
fully automatic tuning unit, integrated in
the antenna head, ensures continuous
matching to the transmitting system with
a VSWR of less than 1.5 if used in R&S
XK2100 systems. No control signals are
required from the transmitter for tuning.
Conventional antennas: the problems
Conventional antennas for operation on
ships such as rod antennas and loop
antennas often cause communication
problems and are incompatible with
other systems on the ship (EMI).
Rod antennas:
◆ Unfavourable radiation pattern over
short and medium distances (skip
zone)
Photo 42826
◆ Poor electromagnetic compatibility
with other systems on board, since for
rod antennas the ship's structure acts
as a ground plane
Loop antennas:
◆ Poor efficiency → low transmission
reliability
◆ Small bandwidths
R&S HX002M1: the solution
The 150 W Dipole R&S HX002M1 solves
such problems since the reactive power
has been minimized in the antenna feed
system. The antenna does not need a
counterbalance – a particular advantage
in GRP ships such as mine sweepers and
patrol craft.

Rotatable Log-Periodic Antenna System R&S® AK451
5 MHz to 30 MHz
For transmission and reception of horizontally polarized
waves over medium to long distances
Brief description
The compact Rotatable Log-Periodic Antenna System R&S AK451
is used for the transmission and reception of horizontally polarized waves. Due to a transmission frequency range from 5 MHz
to 30 MHz, the antenna system is particularly suitable for operation over medium to long distances despite its extremely small
size. Reception is possible from 2 MHz, thus covering all
distances.
Special features
◆ Extremely small dimensions (size of loaded log-periodic
antenna for 6.2 MHz to 30 MHz)
◆ Transmission from 5 MHz, reception from 2 MHz
◆ Unrestricted half-wave elements leading to high antenna gain
◆ Easy and quick assembly
◆ Little maintenance required
Specifications
Frequency range 5 MHz to 30 MHz
Polarization horizontal
Nominal impedance 50

For transmission and reception of horizontally polarized
waves especially over long distances
Brief description
The compact Rotatable Log-Periodic Antenna System R&S
AK471 is used for the transmission and reception of horizontally
polarized waves. Due to its transmission frequency range from 7
MHz to 30 MHz it is used especially over long distances. Reception is possible from 3 MHz to 30 MHz, leading to coverage of
almost all distances. Its low weight and small size make the
antenna system ideal for installation on roofs.
