This antenna utilizes a log-periodic dipole array, which creates a cardioid reception pattern, effectively directing reception to the desired area and rejecting unwanted RF signals from the sides and rear. The WB (Wideband) modification covers an extremely wide frequency range (470–900 MHz), making it versatile and suitable for use with various wireless systems.\u003c\/p\u003e\n\u003cp\u003eThe main advantage of this antenna is its integrated low-noise amplifier with a 4-position gain switch. This allows the user to compensate for signal loss due to long coaxial cables (by selecting +6 dB or +12 dB), or to attenuate the signal (-6 dB) when close to transmitters. The antenna also features a unique RF overload LED indicator, which visually warns of excessively strong signals, helping to prevent distortion. The robust construction is weather-resistant, making it suitable for outdoor installations.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePurpose: Signal reception improvement and directionality (log-periodic antenna).\u003c\/li\u003e\n\u003cli\u003eIntegrated Amplifier: 4-position gain setting (+12 dB, +6 dB, 0 dB, -6 dB).\u003c\/li\u003e\n\u003cli\u003eFrequency Band: Wideband 470–900 MHz.\u003c\/li\u003e\n\u003cli\u003eRF Indication: Integrated LED indicator for RF signal overload warning.\u003c\/li\u003e\n\u003cli\u003eDirectionality: Approximately 70 degrees (Beam Width), ensuring precise coverage.\u003c\/li\u003e\n\u003cli\u003eMounting: Integrated thread for standard microphone stand.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: Active Directional Antenna (Log Periodic Dipole Array)\u003c\/li\u003e\n\u003cli\u003eFrequency Range: 470 MHz – 900 MHz\u003c\/li\u003e\n\u003cli\u003eGain Settings: -6 dB, 0 dB, +6 dB, +12 dB (switchable)\u003c\/li\u003e\n\u003cli\u003eAntenna Beam Width (3 dB): 70 degrees\u003c\/li\u003e\n\u003cli\u003eThird-Order Intercept Point (OIP3): \u003e 30 dBm\u003c\/li\u003e\n\u003cli\u003eConnector: BNC Female (50 Ω)\u003c\/li\u003e\n\u003cli\u003ePower Supply: 10–15 V DC (bias from antenna splitter or receiver)\u003c\/li\u003e\n\u003cli\u003eDimensions (Height x Width x Depth): 316 x 359 x 36 mm\u003c\/li\u003e\n\u003cli\u003eWeight: Approximately 0.317 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIncluded in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Shure UA874WB active directional antenna\u003c\/li\u003e\n\u003cli\u003e1 x 5\/8\" to 3\/8\" thread adapter\u003c\/li\u003e\n\u003cli\u003e1 x User documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWho is it for?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLarge stages and events where receivers are far from transmitters.\u003c\/li\u003e\n\u003cli\u003eProfessional wireless systems (e.g., Axient, ULX-D, QLX-D, SLX-D).\u003c\/li\u003e\n\u003cli\u003eInstallations requiring compensation for long cable losses.\u003c\/li\u003e\n\u003cli\u003eSituations where interference from other directions needs to be eliminated.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shure","offers":[{"title":"Default Title","offer_id":55960154407298,"sku":"1009584","price":475.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0931\/9736\/9730\/files\/ShureUA874WB.webp?v=1764590893","url":"https:\/\/stageiq.lt\/en\/products\/shure-ua874wb","provider":"STAGE IQ","version":"1.0","type":"link"}
