The active AD 808 antenna combiner (4 inputs / 1 output) combines the antenna signals of a maximum of 4 CT 316 UHF transmitters. In simultaneous interpreting applications it is therefore possible to combine a maximum of 3 RF signals of target languages in addition to the original language and to transmit them over a single antnenna (optional). The RF performance is improved and intermodulation is suppressed due to the optimised combiner input filters. The AD 808 is operated in the UHF frequency range between 600 and 900 MHz.

Features:

-  600 - 900 MHz wideband

-  The signals of a maximum of four transmitters can be combined and transmitted via one
   antenna

-  Input Signal Indicator Threshold when input signal > +6 dBm

-  Maximum RF input power +20 dBm efficiency (100 mW)

-  Ideal intermodulation characteristic (full band performance + 15 dBm two-tone test,3rd order
   IM < -57 dBc)

- A maximum of twelve UHF transmitters can be cascaded
