Starpoint Combiner 87.5... 108 MHz, 30 W General Starpoint combiners enable several transmitters or receivers to be connected to one common output. This arrangement provides a cost efficient solution while retaining the advantages of band-pass filter usage. This starpoint combiners consist of one 3-pole bandpass filter per channel. The inputs of the filters are narrowband. The outputs are connected via pre-defined cable lengths onto a common starpoint. This starpoint then forms the output of the combiner. The starpoint combiners may be extended by adding further band-pass filters and by exchanging the starpoint. The combiners are maintenance free and are thus especially safe to operate.

The design enables simultaneous operation at two antennas via common feeder cable. 722 659 Multiband combiner Antenna 87.5 108 MHz Antenna 174 230 MHz Combiner Multiband Combiner 722 659 (with weather protective case) Feeder cable Combiner Multiband Combiner 722 659 87.5 108 MHz 174 230 MHz Antenna Diplexer 1 Antenna Type No. 722 659 87.5 108 MHz / 174 230 MHz Insertion loss < 0.5 db Isolation > 30 db < 1.4 Input power < 50 W (per input) Connections N female 1 kg Color (front plate) Dimensions (l x w x h) 175 mm x 70 mm x 80 mm Packing size (l x w x h) approx. 190 mm x 95 mm x 100 mm Transmitter or receiver High-pass Low-pass 1 3 3 1 Low-pass High-pass 2 2 Diplexer 2 Feeder cable Transmitter or receiver 80

Multiband Combiner 174 230 MHz / 470 790 MHz General Multiband combiners allow several transmitters or receivers of different frequency ranges to be connected to one common output. Design and Function This multiband combiner consists of one high-pass (for 470 790 MHz range) and one low-pass (for 174 230 MHz range). The high-pass as well as the low-pass is built up by using lumped L-C elements. The design enables simultaneous operation at two antennas via commone feeder cable.
