<p>PURPOSE:To save man-hours for TV wiring and to provide enough water resistance by commonly using an indoor TV wiring for BS, CS, and UHF/VHF antennas. CONSTITUTION:A lead-in wiring device has a main body 10 in which terminals connect antenna lines from a BS antenna or CS antenna, and UHF/VHF antenna. The main body 10 is installed at the external wall surface of a building and an incoming line L3 is led indoors from the body 10 through the external wall. A water resistance packing 32 is placed between the external wall and a mounting frame 33 with a hole 33a through which the incoming line L3 is passed. The line L3 is covered with a water resistance packing 43.</p> |
