• 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.

Connect the antenna’s coaxial cable to your audio/video system’s antenna terminals according to the type of connections you 
have.

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.

Complete Step 1 through Step 3 on page 1 before beginning.

Remove the VHF antenna from the mast. 

Mount your HDTV/UHF antenna about 48 inches (1.2 
meters) from the top of the mast. (See Step 4: Attach 
Antenna to the Mast 

on page 1.) 

Attach the VHF antenna to the mast.

Use about 5 feet (1.5 meters) of twin-lead cable to 
connect your HDTV/UHF antenna to the VHF antenna. 
Be sure the cable is long enough to reach from the lead-
in terminals of one antenna to the lead-in terminals of 
the other.

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.

Remove the hardware from the VHF antenna’s lead-in 
terminals.

Wrap each lead around one of the antenna’s lead-in 
terminals (on both sides of the boom) and secure with 

the hardware. Be sure there is enough slack between the 
strain-relief tab and the antenna terminals to prevent stress 
on the cable or the terminals.

Wrap each lead on the other end of the twin-lead 
cable around one of the HDTV/UHF antenna’s lead-in 
terminals (on both sides of the boom).

Secure the leads with the supplied flat washers and 
large wing nuts.
