Go Pro ™ DMR UHF Digital Repeater 

Sometimes  the wireless application calls for a little more walkie talkie...

Introducing the Go Pro™ series GPB, two slot, DMR digital repeater.  With native high and low power capability, correctly located, the Go Pro repeater will more than double/ triple  or more your  effective handheld communications coverage. Now your Go Pro™ Portables can talk wherever your feet take them.

Digital Voice Privacy:

Privacy is a concern for most organisations today whether that be in protecting clients details or sharing company processes, records or sensitive company knowledge. The Go Pro can be configured with a unique encryption key that means only your radios can listen to your conversations. The advanced digital encryption delivers the same clear audio that you get from the Go Pro in its standard digital audio mode delivery voice privacy without compromise.  In these days of every reducing privacy, embedded high level encryption ensure your work conversations stay strictly within in your employee teams  and not accessible to others with a $200 scanner who may want to disrupt your business or cause havoc by recording sensitive conversations and posting it on to social media.

Industrial standard - Premium quality:

Every facet of the Go Pro Repeater has been expertly engineered and painstakingly implemented to provide superior performance with the utmost reliability. Each Go Pro repeater is built to an exacting  standard which has historically only been associated with digital repeaters costing many thousands more that the GPB series.

Besides global technical specification compliance, the Go Pro repeater is designed to meet relevant fixed site environmental conditions as well as other pertinent operational endurance requirements. Unlike many other repeater designs, Go Pro features, a rock-solid, aluminium die-cast core chassis supporting all its radio electronics and associated audio and switching peripheral circuitry. The entire unit is then embedded into a traditional 19” rack mount housing featuring a colour LCD front panel fro accessibility and operation status assessment, making it the perfect choice for standalone or multi-base site arrangements.

Integrated Antenna Duplexer:

The Go Pro Repeater incorporates a high spec antenna duplexer which means installation is a breeze. Simply choose the optimum site location, install and connect the antenna network provided by your supplier. Now plug the GPB by into a nearby AC power point and you are ready to talk. Naturally your supplier can arrange installation services should your required coverage area require the services of professional antenna fitters.
