WHERE TO MOUNT YOUR ANTENNA
Your antenna can be mounted on either the chimney, the roof, or on an outside wall or in an attic. Choose the
method that best suits your particular location. Mast tube size should be 1.25” to 1.66” outside diameter.
TRANSMISSION LINE
75 Ohm coaxial cable. RG-6 if running long distance. RG-6 or RG-59 for short distance.
ASSEMBLING ANTENNA
STEP 1: Remove the bottom cover from the unit. Unsnap the cover from the front end and clam shell open.
STEP 2: With the internal (cavity) part of the housing facing you, slide the left VHF element through the slots in
the left side of the housing. See FIGURE A. Be sure the element slides under the PCB. Slide the element all the
way in so that the slots in the elements are totally around the pre-installed screws. Note: The four screws are
only turned down half way. See FIGURE B.
