Please note:As a result of more stringent legal regulations and judgements regarding product liability, we areobliged to point out certain risks that may arisewhen products are used under extraordinaryoperating conditions.

The mechanical design is based on the environmentalconditions as stipulated in ETS 300 019-1-4, whichinclude the static mechanical load imposed on anantenna by wind at maximum velocity.

Extraordinary operating conditions, such as heavy icing or exceptional dynamic stress (e.g. strain causedby oscillating support structures), may result in thebreakage of an antenna or even cause it to fall to the ground.

These facts must be considered during the site planningprocess.

The details given in our data sheets have to befollowed carefully when installing the antennas andaccessories.In addition, please use our information brochureabout mounting configurations.

The installation team must be properly qualified and also be familiar with the relevant national safetyregulations.

Technical Data

The band-pass filter is suitable as receivingor transmitting filter, for one transmitting orreceiving channel.

It can be used:– to improve the input selectivity of receivers

and amplifiers,– to increase the isolation of transmitters,

whose respective antennas are mountedclose together,

– to suppress noise sidebands and inter-modulation products,

– as a component to form combiners.

Design and construction:The band-pass filter is designed as a tempe-rature stabilized λ/4 coaxial resonator. Thepass band frequency as well as the inputand output coupling are adjustable.

Filter characteristics: Narrow pass band range with low insertionloss, high stop band attenuation, variable fil-ter response corresponding to the desiredstop band attenuation.

Combination of several band-pass filters:Several band-pass filters can be intercon-nected using cables of an electrical length ofλ/4. This causes an increase in the edgesteepness of the filter curve as well as thebandwidth of the pass band. The individualfilters are tuned to the center frequency ofthe complete filter.

Insertion loss of the filter combination = Sum insertion loss of the individual filters + cable attenuation of the interconnectingcables (about 0.1 dB per cable). Stop band attenuation of the filter combination = Sum stop band attenuation of individual fil-ters + additional stop band attenuation.

If the stop band attenuation of the individualfilters exceeds 10 dB, approximately the fol-lowing applies: additional stop band attenuation = (n – 1) x 5 dB;n = number of individual filters.For special applications band-pass filters canalso be interconnected with S-P filters.

Tuning:The band-pass filter is tuned to the desiredpass band frequency and insertion loss at thefactory. Please specify desired pass band fre-quency and insertion loss (curve A, B, C, D)when ordering. The pass band filter can also be tuned onsite using the supplied instructions.

The S-P filter (Stop-Pass filter) is used toattenuate interfering signals located extreme-ly close to the operational frequency.

It can be used:– in the transmission path to suppress

side band noise and to attenuate inter-modulation products at the receiving fre-quencies,

– in the receiving path to attenuate transmit-ting frequencies,

– as a component for combiners with verylow frequency spacing.

Design and construction:The S-P filter is designed as a high Q tempe-rature stabilized λ/4 coaxial resonator. Usinga special temperature stabilized coupling,high stop band attenuation can be adjustedvery close to the pass band frequency.

Filter characteristics: Narrow pass band range with low insertionloss, high stop band attenuation at the stopband frequency. Even in case of very smallspacing between the pass band and the stopband frequency a high stop band attenuationis achieved, which can not be achievedusing standard band-pass filters of the samesize.

Combination of several S-P filters:Several S-P filters can be interconnected bycables with an electrical length of λ/4.

Insertion loss of the filter combination = Sum insertion loss of the individual filters + cable attenuation of the interconnectingcables (about 0.1 dB per cable). Stop bandattenuation of the filter combination = Sum stop band attenuation of the individualfilters + additional stop band attenuation.

If the stop band attenuation of the individualfilters exceeds 10 dB, approximately the following applies:additional stop band attenuation =(n – 1) x 5 dB;n = number of individual filters.For special applications S-P filters can alsobe interconnected with band-pass filters.

Tuning:The S-P filter is tuned to the desired passband and stop band frequency at the factory.Please specify desired pass band and stopband frequency when ordering.

The S-P filter can also be tuned on site usingthe supplied instructions.

The Rx combiner enables two receivers to be com-bined to one common antenna output.

The Rx combiner consists of two 1 pole band-passfilters per channel.

The band-pass filter is designed as a temperaturestabilized λ/4 coaxial resonator.

The intputs of the filters are connected via pre-defi-ned cable lengths onto a common starpoint.This starpoint then forms the input of the combiner.

Tuning:

The band-passes must be tuned to the individualoperating channels. Upon request this tuning maybe performed at our factory (in this case please state the operating channels when ordering) or it may be undertaken on site.

The 3-dB coupler can be used:– as decoupled power splitter with a ratio

of 1:1,– for the decoupled combining of two trans-

mitters with arbitrarily low frequency spa-cing (at 3-dB loss),

– for the decoupled combining of two recei-vers with arbitrarily low frequency spacing,

– for the decoupled combining of two trans-mitter/receiver units, whose integratedduplexers are within the same frequencyrange, as a frequency independent 90°phase shifter,


Design and function:The 3-dB coupler has four ports, two ofwhich are decoupled from each other. For example effective power entering intoport 1 is distributed into ports 2 and 3. Port 4 is decoupled and without power ifports 2 and 3 are ideally matched. In practi-ce an absorber of suitable power is to be planned for according to the mismatchof ports 2 and 3.

Custom versions:On request couplers with a coupling atte-nuation between 3 dB and 10 dB are available.

The 10-dB coupler is used as a decoupled split-ter for power splitting purposes at a 1 : 9 ratio. An effective power entering at e.g. port 1 is divi-ded between the ports 2 and 3 at a ratio of 1 : 9. Thus 1/10 of the input power (attenuation: 10 dB)is available at port 2 and 9/10 of the input poweris available at port 3.Port 4 is decoupled and remains free of power ifthe ports 2 and 3 are ideally matched. In practicean absorber of suitable power at port 4 is to beplanned in accordance with the mismatch of ports2 and 3.

Decoupled combining can be achieved via thediagonally opposite ports 2 and 3 respectively 1and 4.

Technical Data

The circulator can be used:– to increase the coupling attenuation between trans-

mitters, to reduce intermodulation products,– to prevent adverse effects to unmatched load

impedance on amplifier performance.

Function:The circulator is a non-reciprocal component with low insertion loss in the forward direction (1 → 2) and high attenuation in the reverse direction (2 → 1).The impedance at the input (1) of the circulator isconstant and independent of the impedance of thecomponents following, since the reflected power atthe output (2) is passed to the absorber port (3),which must be terminated with an absorber.

Dimensions of the absorbers:The absorber at port (3) must be dimensioned to be able to absorb the maximum power reflected atoutput (2).

Receiver Multicoupler117.5 – 144 MHz, 8 Outputs

Technical Data

The use of the receiver multicoupler 780 265 isappropriate if several receivers are operatedsimultaneously at the same site. With this receivermulticoupler up to 8 receivers can be connected to one common antenna.This results in considerable savings for the antennasystem. The low noise figure and the excellent inter-modulation properties guarantee a high dynamic rangeand thereby improved receiving conditions. This is ofparticular significance in locations where transmitters are also operated next to receivers.

The receiver multicoupler consists of:– a low noise amplifier,– a power splitter,– a voltage supply.

The receiver multicoupler has an active redundancy dueto the two amplifier modules in parallel which are locatedin the low noise amplifier. This means that the receivermulticoupler still supplies all connected receivers even ifone of the amplifier modules fails. The signal levels in thiscase decrease by approximately 6 dB.Each amplifier module is designed for operation with itsown voltage supply of 230 V AC or +11 … +48 V DC.

* hu = height unit

Technical Data

The hybrid transmitter combiner allows two or more transmitters to be combined to a common output.

Special features:– very small spacing of the transmitting fre-

quencies, down to adjacent channel spa-cing,

– variable transmitter frequencies,– small dimensions.

Design:The hybrid transmitter combiner has two,three or four inputs and one output. For combining transmitters a hybrid ringjunction or a decoupled power splitter isused as hybrid, depending on the numberof inputs. In every transmitting path a wideband dual circulator is inserted, which cau-ses very high islotaion. This effectively sup-presses intermodulation products. Theabsorbers are dimensioned for a possibilityoccurring total reflection at the output.

Custom versions:Custom versions are available on request:– with single circulator instead of dual cir-

culator, if lower isolation is sufficient,– with a band-pass filter at the output,– for higher power.

It can be used:– to improve the input selectivity of recei-

vers and amplifiers,– to increase the isolation of transmitters,




Design and construction:The band-pass filter consists of three high Q capacitively coupled resonators. The pass band frequency, the coupling be-tween the resonators as well as the input and output coupling are adjustable.

Filter characteristics: Narrow pass band range with low insertionloss, high stop band attenuation, variablefilter response corresponding to the desiredstop band attenuation.

Tuning:The band-pass filter is tuned to the desiredpass band frequency and insertion loss atthe factory. Please specify desired passband frequency and insertion loss (curve A,B) when ordering.

The band-pass filter can also be tuned onsite using the supplied instructions.

The Tx combiner enables several transmitters to be combined to one common antenna output.

Special features:– narrow channel spacing between Tx frequencies

possible,– low insertion loss,– high isolation between Tx inputs,– high filter selectivity at Rx frequencies.

Design and construction:The Tx combiner consists of one douple circulatorand one 3pole band-pass filter per channel. The outputs of the filters are connected via pre-defined cable lengths onto a common starpoint.This starpoint then forms the output of the combi-ner.

Tuning:The bandpasses must be tuned to the individualoperating channels at our factory (please state theoperating channels when ordering).

Technical Data

The circulator can be used:– to increase the coupling attenuation between trans-

mitters, to reduce intermodulation products,– to prevent adverse effects to unmatched load

impedance on amplifier performance.

Function:The circulator is a non-reciprocal component with low insertion loss in the forward direction (1 → 2) and high attenuation in the reverse direction (2 → 1).The impedance at the input (1) of the circulator isconstant and independent of the impedance of thecomponents following, since the reflected power atthe output (2) is passed to the absorber port (3),which must be terminated with an absorber.

Dimensions of the absorbers:The absorber at port (3) must be dimensioned to be able to absorb the maximum power reflected atoutput (2).

Technical Data

The 3-dB coupler can be used:– as decoupled power splitter with a ratio

of 1:1,– for the decoupled combining of two trans-

mitters with arbitrarily low frequency spa-cing (at 3-dB loss),

– for the decoupled combining of two recei-vers with arbitrarily low frequency spacing,

– for the decoupled combining of two trans-mitter/receiver units, whose integratedduplexers are within the same frequencyrange, as a frequency independent 90°phase shifter,


Design and function:The 3-dB coupler has four ports, two ofwhich are decoupled from each other. For example effective power entering intoport 1 is distributed into ports 2 and 3. Port 4 is decoupled and without power ifports 2 and 3 are ideally matched. In practi-ce an absorber of suitable power is to be planned for according to the mismatchof ports 2 and 3.

Custom versions:On request couplers with a coupling atte-nuation between 3 dB and 10 dB are available.

Receiver Multicoupler225 – 400 MHz, 8 Outputs

Technical Data

The use of the receiver multicoupler 780 231 isappropriate if several receivers are operatedsimultaneously at the same site. With this receivermulticoupler up to 8 receivers can be connected to one common antenna.This results in considerable savings for the antennasystem. The low noise figure and the excellent inter-modulation properties guarantee a high dynamic rangeand thereby improved receiving conditions. This is ofparticular significance in locations where transmitters are also operated next to receivers.


The receiver multicoupler has an active redundancy dueto the two amplifier modules in parallel which are locatedin the low noise amplifier. This means that the receivermulticoupler still supplies all connected receivers even ifone of the amplifier modules fails. The signal levels in thiscase decrease by approximately 6 dB.Each amplifier module is designed for operation with itsown voltage supply of 230 V ~ or 11 … 48 V =.

Load50 Ω

50-Ω loads are suited as absorbers for small and medium power.

They are used:– as termination for transmitters or amplifiers used for testing,

measuring or tuning,– as termination for circulators, directional couplers, hybrid

ring junctions and decoupled power splitters.

Special features of the loads are:– very low VSWR within a wide frequency range,– high stability and RF shielding due to the closed aluminium

construction,– arbitrary installation position because of convectional

cooling,– 50 W and 100 W models can be installed on front or rear

panels of electrical equipment for heat dissipation.
