This booster is inserted between the antenna and the wireless receiver using BNC connectors to compensate for signal loss caused by coaxial cable runs, antenna splitter insertion loss, or antenna placement at a distance from the receiver equipment.\u003c\/p\u003e \u003cp\u003eUnlike the wideband AB 3700, the AB 4-AW+ is tuned to a specific frequency range, providing optimized performance and filtering within the AW+ band. This band-specific design reduces the risk of out-of-band interference being amplified along with the desired signal, making it a cleaner solution for installations in congested RF environments where multiple wireless systems and broadcast signals coexist.\u003c\/p\u003e \u003ch2\u003eKey Features\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e+10 dB active gain for the AW+ band (470-558 MHz)\u003c\/li\u003e \u003cli\u003eBNC connectors for inline installation\u003c\/li\u003e \u003cli\u003eBand-specific filtering reduces out-of-band interference amplification\u003c\/li\u003e \u003cli\u003eCompact inline form factor\u003c\/li\u003e \u003cli\u003eDesigned for Sennheiser Evolution Wireless and compatible systems\u003c\/li\u003e \u003cli\u003eCompensates for cable loss and splitter insertion loss\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eProfessional Applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eExtended antenna cable runs in the AW+ frequency range\u003c\/li\u003e \u003cli\u003eCompensating splitter insertion loss in multi-receiver antenna systems\u003c\/li\u003e \u003cli\u003eFixed installations including churches and worship facilities with remote antenna placement\u003c\/li\u003e \u003cli\u003eTouring productions operating in the 470-558 MHz band\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e \u003ch3\u003eCan I use the AB 4-AW+ outside the 470-558 MHz range?\u003c\/h3\u003e \u003cp\u003eNo. The AB 4-AW+ is tuned specifically for the AW+ band. Using it outside this range will not provide the intended gain and may attenuate signals in other frequency bands.
