The Active Directional Antenna HE 100 from Rohde & Schwarz meets

all the requirements a modern, hand-held DF antenna should fulﬁl:

- Una mbigu ous determin ation of di recti on of incid ence, 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

- S u i t a b i l it y f or v e rt i c a l ly a n d h o r iz o n t a ll y p ol a r i z ed s i gn a l s

- Wide dynamic range due to selectable sensitivity permitting use

even in e xtrem ely int ense elec tromagne tic ﬁelds

- Low current drain

1 Use s

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.

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.

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 varia tions in signal st rength caused by d isturbances of the electromagnetic ﬁe ld d ue to l oc al i nﬂ ue nc es do n ot i mp ai r the measurement.

If it is not possible to ﬁnd a pronounced maximum, the effect of re ﬂ e c t i ons i s t o o g r e a t . S u c h r e ﬂ ectio n s or inte r f e r ence are caused whenever electromagnetic waves hit large objects with a
