DESCRIPTION:
The J-105-HI-WC is a heavy duty 75-ohm antenna, specifically designed for master antenna (MATV) distribution
systems.
ASSEMBLY AND MOUNTING:
1. Carefully read through the instructions and study the figures before you begin installation of the antenna.
2. Inspect antenna visually upon reception for shipping damages and report them immediately if any have
occurred.
3. Swing the front of the crossarm into position and secure it to the main upper crossarm with the machine
screw, lock washer and hex nut supplied; wrench tighten both securing hex nuts. (see Figure 1)
4. Assemble the elements onto the crossarms in their respective positions as denoted by their length. Note the
