Product Introduction:^#^1.Product Name:car radio signal amplifier antenna booster^#^2.Voltage: 12V^#^3.Color: Black^#^4.Able to provide high output current, low harmonic distortion and cross, to ensure security operation, due to the DC and AC short circuit protection on all pins and ground, thermal limiting circuit, load dump voltage surge protection up to 40V and the case of open space protection diodes accident.^#^ ^#^ ^#^Product Features:^#^1. Improved performance TDA (PIN-to-pin compatibility).^#^2. Very low external component count.^#^3. Easy to assemble, saving cost and space.^#^ ^#^ ^#^NOTE:This item is used to enlarge the signal,if the antenna reception is very bad or there is no signal,it will not work.
