Why Radio Active Designs?

When wireless systems were introduced more than 50 years ago, they operated only in the VHF bands (30 MHz to 300 MHz). As technology progressed, there was a great deal of movement to the UHF band, as it was far less congested at the time.

With the re-allocation of the 600 MHz band, VHF technology is once again center stage. Incorporating new manufacturing techniques and sophisticated DSP technology into VHF products eliminates many of the RF and audio quality issues from a generation ago, all while keeping the size down.

Radio Active Designs currently uses the VHF spectrum for the UV-1G wireless intercom system. The UV-1G base station takes up a very small footprint in UHF transmit frequencies while the belt packs operate in the relatively open VHF band, freeing up a significant amount of UHF bandwidth for wireless mics and IEM systems. The UV-1G is the best choice for large intercom intensive events, small “dry hire” rentals and everything in between.

The auction in a nutshell…

The FCC has reached its goal of auctioning off everything above 608 MHz. What the auction means is that all entertainment production wireless operations in the U.S. will have to change. The auction forces entertainment wireless users to operate in a greatly reduced percentage of the UHF bandwidth. To help alleviate some of the issues caused by the auction, the FCC has opened up some bandwidth in the higher bands for entertainment wireless use.

However, these much higher frequency bands may not be conducive to reliable wireless system use beyond relatively short distances. The higher you go in the spectrum, the more difficult it is to make wireless work the way that we in the production community use it.

Why VHF?

Reliability
Range
High Channel Count
Ease Of Use
Simple Antenna Distribution

What Our User’s Say…

“At one point the opening ceremony had over 100 kids on the field forming the flags of each participating country. They all had to be wrangled into place by 5C production staff with split second timing, all this while there were more than 20 mics and IEM’s dedicated for the artists that performed and a total of 160 frequencies in the coordination… From the get go I said ‘we need to keep as much UHF available as possible’ – which is exactly what the RAD gear does. We had the UHF bandwidth we needed and the UV-1G systems provided flawless communications for both events.”
