Kaltman Creations LLC, an Atlanta-based producer of radio frequency (RF) analyzers, antennas and frequency counters, is offering the RF-id SOLO and RF-id STATION, which help identify wireless devices’ frequencies.

ess devices, Kaltman says.

The RF-id STATION is primarily for professional audio wireless users while the RF-id SOLO is aimed at audio technicians, production companies, contractor/installers, frequency coordinators, or anyone involved pro-audio wireless related applications, the company says.

The RF-id STATION enables RF technicians to efficiently “stage” and manage wireless microphones before and during a live event/performance, the company says. The unit consists of a rugged plastic carrying case with eight designated foam-formed slots for wireless microphones or wireless belt pack transmitters.

Each slot has a backlit, near-field frequency counter readout providing the exact frequency of the transmitter and a barograph signal level display. Up to eight transmitters can be staged at one time and swapped-out as needed, Kaltman says. Just below the frequency counter display is a dry/erase, write-on strip to help keep track of microphone/transmitter assignments, the company says.

As a value-added feature, each of the eight slots is individually RF shielded to reduce the effects of close proximity intermodulation, and to reduce stray transmissions into the performance area. And the station can also be used as a microphone and accessory carrying case with storage for up to 18 transmitters, the firm says.

In addition, the RF-id SOLO’s liquid crystal display (LCD) readout enables users to simultaneously—and instantly—confirm exact frequencies and transmission signal strength, avoiding the need to handle the transmitter (which often involves menu scrolling and converting group and channel readouts to frequency values). The unit works with both digital and analog single carrier transmissions in the 50-megahertz to 2.5-gigahertz range, and is not limited to just wireless microphones use, the company says. The unit can also be used with assisted listening devices, intercom, cell phones, two-way radio and commercial RFID tags, provided that the transmissions are not “a spread-spectrum, or frequency hopping,” according to the company.

“These days, with all of the RF allocation turmoil and the ever-shrinking RF space, RF technicians need all the help they can get to efficiently manage their RF world,” says Mark Kaltman, Kaltman Creations’ president. “The Invisible Waves RF-id Station is a new and effective tool for your RF arsenal, and the RF-id Solo, with the ability to walk right up to a concealed/worn belt pack transmitter or wireless microphone and instantly confirm that the device is transmitting along with an exact frequency reading, is very powerful,” he said.
