【Product Description】 Toshiba TOSHIBA Digital Terrestrial Broadcasting Flat UHF Antenna, Indoor/Outdoor Use DUA-1000 This is a model for both indoor and outdoor use. Please note that the operating condition will vary depending on the distance from the broadcasting tower and the environment. We cannot guarantee reception quality as it depends on the radio wave conditions. Features ● This antenna receives UHF band (ch13-52). ● It can be used as an indoor antenna by attaching the stand (included), or as an outdoor antenna by attaching the mast clamp (included). ● By changing the mast clamp (included), it can receive both horizontal and vertical polarization. (When the stand (included) is attached, it is for horizontal polarization reception only.) ● The directivity is wide, making it easy to adjust the direction left and right. ● Snow is less likely to directly accumulate on the antenna elements, resulting in less performance degradation due to snowfall. The outer box was opened for photography, but the contents have not been taken out of the bag, so it is listed as a new, unused item. Please understand that this item has been stored at home before considering purchase. Feel free to negotiate the price!
