Philips HDTV digital TV indoor 20dB amplified antenna. It features amplification of both UHF and VHF signals. It uses household 120V current (with supplied power cord) and has a range of 25 miles from the signal source. We are fortunate to have many channels broadcasting here in DFW. At our place here in Irving, I get pick up about 40 channels with mine. Get rid of cable or Dish and pay nothing each month to pick up many channels on your digital television. These will also work with older style analog TVs but you will also need a converter box. We have several available and they are brand new in the box. $25 each.. Come visit us in Irving at Recycled Furniture to see more of what we have on our shelves and in our warehouse.
