Step 5: Route the Cable to Your Audio/Video System

Adding the HDTV/UHF Antenna to a VHF Installation

•Use plastic tape or mast standoff insulators to secure the coaxial cable to the mast at about 3-foot (.9 m) intervals. Continue down the roof and the side of the house using roof and wall standoff insulators.

•Use a 75-ohm grounding block at the point where the coaxial cable enters the house. Read the Consumer Product Safety Commission Sheet for grounding instructions.

•Use a wall-through lead-in tube (not supplied) to neatly route the coaxial cable through walls. Loosely bend the cable to form a drip loop before the cable enters the house.

Step 6: Connect to your Audio/Video System

Connect the antenna’s coaxial cable to your audio/video system’s antenna terminals according to the type of connections you have. RadioShack carries a variety of splitters and other accessories; choose one that best suits your needs. Below are some

sample connections.

There are many methods you could use to add an HDTV/ UHF antenna to an extising VHF installation. This section describes one method, which is to mount your HDTV/UHF antenna below the VHF and connect the two antennas with twin-lead cable. Visit your local RadioShack store to ﬁnd the best method and mounting accessories for your installation.

Note: You could also place your HDTV/UHF antenna above the VHF, but the coaxial cable must feed from the HDTV/ UHF antenna.

3.	Attach the VHF antenna to the mast.
4.	Use about 5 feet (1.5 meters) of twin-lead cable to
	connect your HDTV/UHF antenna to the VHF antenna.

	in terminals of one antenna to the lead-in terminals of
	the other.
5.	Split both ends of the twin-lead cable for a length of
	about 3 inches (7.6 centimeters). Then strip about ½
	inch (1.2 centimeters) of insulation from all leads.
