The Motorola CDR500 repeaters provide the perfect solution. By making it easy to extend your two-way system to accommodate longer distances, these repeaters let you widen the reach of your radios as you broaden your customer base.

Unique Versatility and Power

The Motorola CDR500 repeaters offer extensive functionality and power to help you increase the calling range and capabilities of your mobile or portable radios – so you can enhance on-the-job efficiency. By receiving and resending radio transmissions these powerful repeaters help you extend your communication range and maintain clear sound quality. Available in lowband, UHF, and VHF frequencies, the Motorola CDR500 repeaters suit a wide variety of applications and can be easily integrated with your existing infrastructure.

The CDR500 offers a variety of mounting options to suit your location and usage needs.


Smart professionals in every business know that reliable communication is essential to success. Whether you’re in the office or on the road, you need fast, dependable access to the right people and information so you can get the job done. And that’s exactly what two-way radio delivers. Efficient two-way radio lets you talk with one, ten, or one hundred people at the touch of a button – without costly airtime charges. Two-way radio provides the individual and team contact you need to help maximize productivity and meet your customers’ demands – the first time and every time.

The Motorola CDR500 repeaters deliver valuable benefits, including:

  • Remarkable flexibility that allows you to choose the frequency and power levels best for your business – or combine two frequencies to create a bidirectional or crossband repeater.
  • The Motorola CDR500 offers a variety of mounting options to suit your location and usage needs. It can be installed in a 19 inch rack or mounted on the wall with a handy, lockable wall mount.
  • The Motorola CDR500 desktop model offers sleek, compact design that compliments any office décor – and allows quick and easy access for system adjustments.
  • Reliable, cost-effective 15A continuous duty power supply that allows selection of either thermal-controlled or continuous operation of the fan for quiet performance and enhanced efficiency on the Motorola CDR700 model. Don’t wait to take your business communication to the next level.

Controllers offer you a range of options to accommodate your market
and application requirements. A unidirectional configuration provides
added range for radios on widespread worksites. A bidirectional
configuration can temporarily join two separate groups during critical
situations. Unidirectional crossband provides the capability to monitor
frequencies such as weather or road condition channels, and bidirectional
crossband can temporarily join two groups that normally operate on
different frequency bands.

Duplexers let you use just one antenna for both transmitting and
receiving signals. The use of a duplexer is more cost effective than
two antennas and feed lines, and can better equalize the transmit
and receive ranges to improve radio communications.
