Progressive Field Revamps Communication with Radio Active Designs

Cleveland, Ohio (June 2017) — Progressive Field, home to Major League Baseball’s Cleveland Indians, has recently undergone a system upgrade that includes the installation of two Radio Active Designs UV-1G wireless intercom systems.

Michael Ramirez, the stadium’s audio-video engineer, added two UV-1G base stations and 12 RAD packs to improve communications for game day staff – which includes camera operators, advance team coordinators, mascot coordinators, on-field anthem singers, and others involved in game day production.

“We needed a system that didn’t operate in 2.4 GHz – which was allocated for stadium Wi-Fi – and that would provide the clarity of an analog signal,” explains Ramirez.  “Because RAD is analog and operates primarily in the VHF band, it seemed like the obvious choice. After presenting the most consistent results of all the systems tested, it was an easy decision. Knowing frequencies would change in the future and that we were adding Wi-Fi to the building, the UV-1G was our best bet.”

The base stations are rack-mounted in the scoreboard rack room located behind home plate, providing exceptional coverage in the stadium bowl. When systems are utilized outside of the park Ramirez deploys an antenna to extend that coverage beyond the dense concrete walls of the stadium.

“It’s an older park with lots of cement, so getting any signal outside of the park is impossible,” adds Ramirez. “Fortunately, one antenna does the trick, which makes using the systems beyond the stadium walls very convenient.”

With UHF at a premium, it was important that the intercom system take up minimal RF bandwidth. As luck would have it, the UV-1G base station requires less than 30 kHz of the UHF band and the RAD packs operate completely in VHF. This made keeping valuable UHF bandwidth open for other wireless devices to operate easier.  As an added benefit, since the VHF band is virtually empty, every comm operator has their own channel, eliminating issues that can occur when forced to “double-up”, which is necessary with some bandwidth-challenged UHF systems.

With last year being the first season the UV-1G was in use, Ramirez has nothing but good things to say about the system at the start of this year’s season. “We have not had any issues, beyond normal wear and tear. The system is solid. The RAD systems work really well and were easy to integrate with systems we already had in place. We have accomplished exactly what we set out to and I’m quite pleased with the end result.”

Radio Active Designs Drives Communications During Detroit Auto Show

Ann Arbor, Michigan-based Amazing Audio recently frequency coordinated nine Radio Active Designs UV-1G wireless intercom systems for press events for the annual North American International Auto Show (NAIAS), held in Detroit, Michigan. Amazing Audio’s Jeff Jones provided RF coordination for the event.

“Given how crowded the RF spectrum was, it would have been impossible to deploy enough RF intercoms,” explains Jones. “Fortunately, RAD systems operate primarily in VHF with the base stations taking up only a sliver of UHF bandwidth. So we were able to use nine base stations and 54 RAD packs, which helped tremendously when coordinating press events of this size.”

Jones used 603 RF frequencies during Press Week. Seven major audio manufacturers hosted press events that also utilized the RAD intercom systems. General Motors (Bluewater Technologies) and Ford (Center Stage Inc., Digital Black Inc.), each put two UV-1G systems to use, while Volvo (Creative Technologies), Hyundai (Creative Technologies) Lexus (Creative Technologies), Volkswagon (Riedel/Germany) and Lincoln (Digital Black Inc.) used individual systems for each of their events.

Radio Active Designs’ Enhanced Narrow Band technology allows the units to fit more than ten times the amount of wireless systems in the same band as traditional RF Intercom systems. As a result, even the base stations, which operate in UHF, have a very small footprint in the UHF band – making them invaluable at an event of this scope.

“We used five base stations and 30 RAD packs at the 2015 NAIAS Press events,” adds Jones. “This year we bumped up to nine base stations and 56 RAD packs. They free up so much bandwidth – which we need for RF microphone use – the UV-1G is the future of wireless intercoms.”
