The Active Directional Antenna HE 100 from Rohde & Schwarz meets
all the requirements a modern, hand-held DF antenna should fulfil:
- Unambiguous determination of direction of incidence, i.e.
distinct directional pattern
- Antenna voltage maximum as direction criterion (maximum-signal
DF method)
- Handy size, in particular minimum crosswise dimensions, and low
weight
- Suitability for vertically and horizontally polarized signals
- Wide dynamic range due to selectable sensitivity permitting use
even in extremely intense electromagnetic fields
- Low current drain

1 Uses
Due to its small size and low weight, the Active Directional
Antenna HE 100 in conjunction with a compact, portable receiver
(e.g. EB 100) is ideally suited for tracing signal sources and
sources of interference.
The direction of the signal source is found by pointing the an
tenna towards the direction of maximum signal voltage. The
overall frequency range from 20 to 1000 MHz is covered by three
exchangeable antenna modules, which handle both vertically and
horizontally polarized signals and have almost identical cardioid
radiation patterns in both planes.
In order to increase the sensitivity, a low-noise amplifier can
be switched into circuit (active/passive switchover). As this
amplifier is bypassed during passive operation, the HE 100 can
also be used in the vicinity of powerful transmitters.
Camouflaged use of the antenna, for instance in a suitcase or a
travelling bag, is also possible.
2 Description .
The broadband, cardioid directional pattern of the HE 100 is
obtained by using loaded loop antenna modules of different size
for the three subranges of 20 to 200 MHz, 200 to 500 MHz and 500
to 1000 MHz. These RF modules can be plugged on to a handle,
which contains the following:
- Power supply, which comes from a set of four round cells R6
(dry or NiCd cells) contained in a removable battery holder.
- Antenna electronics, comprising RF amplifier, active/passive
switch and circuitry for the meter.
In the active mode, the RF signal path is taken via an RF relay
(when supply voltage is switched on) to the low-noise amplifier,
which is bypassed in the passive mode.
- Meter, which indicates the strength of the incoming signal. The
pointer deflection is controlled by the receiver via the RF
cable. The meter, which can be illuminated, also indicates the
state of the batteries at the push of a button.

3 Operation
(see drawing 701.5002.01)
a) Replacing RF modules:
Release catch by pressing two studs (2) and pull out RF module
Plug in required RF module until it locks in position.
b) Active/passive switchover:
Select the desired mode by means of pushbutton (3).
c) Meter indication of state of battery:
Press pushbutton (8) for the battery test on the meter; red
marking: battery discharged.
d) Meter illumination:
The illumination is switched on by pressing pushbutton (4).
e) Replacing battery:
Open the cover (7) of the battery compartment and replace bat
teries in holder.

P r a c t i c a l H i n t s _
In order to obtain optimum results, hold the antenna with the arm
fully stretched out to find the signal maximum. The centre of
rotation should go through the antenna (see Fig. 1) to make sure
that any variations in signal strength caused by disturbances of
the electromagnetic field due to local influences do not impair
the measurement.
If it is not possible to find a pronounced maximum, the effect of
reflection s is too great. Such re flec tions or interfer enc e are
caused whenever electromagnetic waves hit large objects with a
hig h diele ctri c cons tant or good el ectr ical c onduc tivi ty.
It is advisable to take bearings from several points, gradually
coming closer to the transmitter (see Fig. 2).
