Professional Wireless Systems (PSW) is showcasing its range of RF solutions at InfoComm 2014 in Las Vegas (booth C11816), including the GX Series of combiners, DB Series of multicouplers, helical antennas, domed helical antennas, and various accessories such as splitters, dual bias Ts and receive and transmit line amps.
“InfoComm is the ‘can’t miss’ AV technology show of the year, and we look forward to demoing our range of state-of-the-art RF and wireless equipment to the industry professionals in attendance at the show,” says Jim Van Winkle, general manager, PWS. “In addition to showcasing our RF solutions, PWS representatives will be on hand to discuss our ability to provide onsite install services and show support for wireless systems at broadcast, industrial, live entertainment and media events of any size.”
The GX series of combiners, the GX-4 and GX-8, offer selectable high- and low-output settings as well as above unity gain on output. Helpful for anemic transmitters, the combiners in the GX series are considered RF limiters because of proprietary Automatic Level Control (ALC) circuitry.
The power level of each frequency at the output of the combiner is a maximum of 250 mW licensed, 50 mw if not licensed. This is the FCC’s maximum allowable limit for RF in-ear monitor (IEM) systems in the UHF band. The GX-4 is an RF IEM transmitter combiner/booster, compatible with RF signals from major IEM transmitter manufacturers across the radio band from 470 MHz to 698 MHz. The system accepts input power levels from 20 to 100 mW, with each input containing its own discreet RF amplifier and ALC circuits. The signals are amplified to the power level needed to produce up to 250 mW of RF at the output antenna port.
The DB Series of multicouplers includes the DB8 (8 outputs), DB16 (16 outputs) and DB24 (24 outputs). These diversity systems are designed to distribute antenna signals to multiple receivers without loss and with high isolation between ports. Outputs can be put into ranges, providing the user the ability for low, middle and high as well as custom ranges for frequencies. The systems come with features providing the user with maximum control as well as two power supplies, ensuring that if there is a power failure, backup is available.
Two of PWS’ flagship product lines, helical antennas and the new domed helical antennas, offer users extreme flexibility. The circularly polarized UHF antennas cover a frequency range of 450 MHz to 950 MHz and offer 14dbi gain and 8.5dbi for the domed helical. The antennas also provide an inherent boost in gain, greater bandwidth, and dropout-resistant polarization.
Additionally, PWS has recently begun to streamline its manufacturing process to accommodate faster turnaround time when it comes to product development. “To continue to provide the necessary support and high-level functionality on today’s in-demand productions, we are constantly looking for ways to improve both our products and our services, as a company,” adds Van Winkle. “We specialize in frequency coordination that is solid, accurate and constant, as is our workflow.”
