Retransmission set ZRR3801

Retransmission set ZRR3801

 

  • Frequency band 80, 160 and 450 MHz
  • Power up to 25W
  • Programmable channels 511
  • Automatic and local work

Retransmission set can be applicable for simplex, duosimplex or half duplex Radio Access Network communications. This retransmission increases the coverage of communication betweens mobile radio-phones users. This set enables also the communications betweens the radios, which works in different frequency ranges. The presented simple set is designed for work at not expanded communication networks. It can be applied to taxi-drivers corporations, municipal police, health service and many more users. The retransmission set is designed for the continuous work in closed, unheated space.

This set can work at the one of 511 channel pairs with or without Continuous Tone Coded Sub-audible Squelch (CTCSS). It is designed for a power supply of 230V/50Hz and 12V battery supply. When two power supplies are used and mains voltage is lose it is assured the automatic passing to battery supply and the battery charging when the mains voltage is appeared. The transceiver devise is produced in three different frequency ranges:

  • 3821 (frequency range 68÷88MHz)
  • 3821 (frequency range 68÷88MHz)
  • 3851 (frequency range 420÷470MHz)
