Unlike the omnidirectional A 3700, the AD 3700 uses a directional pickup pattern that focuses RF sensitivity toward the performance area while rejecting interference from behind and to the sides, providing cleaner reception in RF-congested environments.\u003c\/p\u003e \u003cp\u003eThe directional pattern is particularly valuable in large venues, multi-stage festivals, and broadcast environments where multiple wireless systems operate simultaneously. By narrowing the antenna's field of reception, the AD 3700 reduces pickup of off-axis interference from neighboring stages, production equipment, and external RF sources, resulting in more reliable wireless operation across all channels.\u003c\/p\u003e \u003ch2\u003eKey Features\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eActive directional antenna with focused pickup pattern\u003c\/li\u003e \u003cli\u003eAdjustable gain: 5 dB, 10 dB, or 15 dB\u003c\/li\u003e \u003cli\u003eWideband coverage: 470-866 MHz\u003c\/li\u003e \u003cli\u003eBNC connector with 3\/8-inch mounting thread\u003c\/li\u003e \u003cli\u003eDC power via coaxial cable from compatible receivers\u003c\/li\u003e \u003cli\u003eCompatible with EM 2000, 2050, 3731, 3732, and 6000 receivers\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eProfessional Applications\u003c\/h2\u003e\u003cp\u003eCommonly deployed in church, house of worship, and professional AV environments.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eLarge venue and arena wireless systems requiring focused coverage\u003c\/li\u003e \u003cli\u003eMulti-stage festivals where RF interference from adjacent stages is a concern\u003c\/li\u003e \u003cli\u003eBroadcast facilities with congested RF environments\u003c\/li\u003e \u003cli\u003eLong-throw antenna deployments in theaters and performance halls\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e \u003ch3\u003eWhen should I use the AD 3700 instead of the A 3700?\u003c\/h3\u003e \u003cp\u003eUse the AD 3700 when you need to focus reception on a specific area and reject interference from other directions.
