Product Info

Dual mode and automatic change
Hytera RD985 repeater can be operated both in analogue and in digital mode and is completely compatible to the currently used analogue systems. Hytera RD985 repeater can automatically change between digital and analogue mode depending on the type of receiver signal, and thanks to the elimination of manually configuring frequencies and channels both time and money are saved.

100% efficiency
Hytera RD985 repeater offers a constant power (up to 50 watt) and in this way meets the high requirements of all conventional digital radio systems.

Flexible installation options
Hytera RD985 repeater can be installed in a 19-inch equipment rack with an optional installation kit. Alternatively, you can easily install it on a rack, a mounting support or a work table. Thanks to the space intended for an optional duplexer inside the device, the device remains compact.

Efficiency in the high-frequency range
Thanks to the applied TDMA technology, twice as many users can use the same channel as in case of analogue or digital FDMA systems. Due to the restricted frequency resources, this represents an important relief and reduces the expenses for system terminals and frequency licences.

Secure communications
Hytera RD985 repeater includes an expanded digital encryption function which protects your communication against wire tapping.

High cooling capacity
Thanks to the heat dissipation the power amplifier can dissipate its heat extraordinarily efficiently. In addition, the integrated fan system supports the stable and efficient operation.

Operation in repeater and/or basic mode
If the Hytera RD985 repeater is operated on an analogue channel, you can select between repeater mode and basic mode. In basic mode Hytera RD985 repeater can be used as a duplex transceiver.

High reliability
Since the Hytera RD985 repeater was designed according to military standards, it offers high reliability and excellent performance. The test results of independent laboratories showed that the trouble-free service life of the device amounts to up to 100,000 hours, thus meeting the requirements of use in extreme situations.
