Hytera RD985 Repeater DMR & FM UHF 50W

PRODUCT DESCRIPTION

The digital repeater RD985 is the heart for multi-cell conventional DMR radio networks and was developed according to the ETSI standard for DMR. It offers an ergonomic design, reliability and outstanding digital functions for sophisticated communication. RD985 – Your digital advantage over your competitors!

All the repeaters from Hytera can be connected in digital mode via IP connection to a comprehensive radio network. In analog mode, the repeaters can be connected together back-to-back. Both in conventional analog and DMR modes (DMR Tier II), the RD985 repeater can be used together with the RD985S, RD625 and RD965 repeaters in a radio system.

Thanks to the TDMA technology, twice as many users can use the same channel, such as is the case with analog or digital FDMA systems. Due to the restricted frequency resources, this represents an important relief and reduces the expenses for system terminals and licenses.

To protect your radio communications against eavesdropping, the RD985 repeater possesses advanced digital encryption functions, according to the DMRA specification. Depending on the variant, the RD985 supports 40-, 128- or 256-bit encryption. With air interface encryption signaling and communications data between radio and repeaters are transmitted with reliable protection.​

The repeater offers an adjustable transmitting power of up to 50 Watt and thereby satisfies the high requirements for modern PMR radio systems.

Since the repeater was designed according to military standards, it offers high reliability and excellent performance. Test results from independent laboratories have shown that the repeater can be operated for up to 100,000 hours without interference (MTBF) and it therefore meets the requirements for use in extreme situations.

The RD985 repeater can be installed in a 19-inch equipment rack with an optional installation kit. Alternatively, it can easily be operated on a rack, a bracket or a table. With the additionally available installation kit, an optional duplexer can be housed in the chassis

Whether during ongoing operation or during a maintenance task: You can easily access all the desired information via the large LCD color display.
