KING knows how important it is for you to stay connected to the world on all your adventures. That's why they've reinvented their KING Jack line with the latest technology to bring you the best directional over-the-air antenna available. Better signal for more free channels, updated sleek design, easy to use. With its high-tech yet simple design, the KING OA8300 Jack digital HDTV antenna provides greater performance than expected from such a compact over-the-air TV antenna. KING Jack is designed for exceptional performance for the demands of either RV or residential use (indoor or outdoor), with long-range signal acquisition. KING Jack's wider reception area makes it easier to lock on to available TV signals. KING Jack is less directional than traditional TV antennas which provides more channels with less need to rotate the antenna; yet, it still provides powerful signal performance with a built-in amplifier powered through your coax using the included 110v power-injector. KING Jack delivers significantly improved performance for UHF signals where more than 80 percent of new DTV channels are broadcast while still providing great reception of existing VHF channels. KING Jack is up to 70 percent smaller than traditional TV antennas and offers less wind resistance; plus, it's simple to install on your RV or in your home attic or roof.
