2. Loosely assemble the dual "U" bolt mounting bracket onto the crossarm as shown in Figure 3.
3. Lift the antenna into position, hold it upright and slide its "U" bolt assembly onto the mast.
4. Orient the antenna in the desired direction, then tighten the hex nuts on the "U" bolts sufficiently for
supporting the antenna.
Description
The J-series Yagi antennas are heavy duty 75-ohm or 50-ohm antennas, for MATV and CATV applications.
Assembly and Mounting
1. Consult Figure 1 or 2 and Table 1 or 2, then assemble the elements onto the crossarm in their proper
positions as denoted by their length. Note that the back of the crossarm is the end with the orange
plastic plugs. DO NOT overtighten the hex-bolts securing the elements.

Attach down lead and weatherproof connection appropriately.
Final Orientation
Rotate the antenna until maximum signal strength is received, then fully tighten the hex nuts on the "U" bolt
assembly.
Arrays
J-Series 75-ohm antennas may be attached both vertically and horizontally for greater gain and directivity. It
is essential that the spacings given below in Figure 4 and Table 3 be strictly adhered to for best possible
results.
The gamma feeds of all antennas within the array must face in the same direction for proper polarity. Note
that the feeds shown in Figure 4 all face right as viewed from the front of the antenna.
Splitting harnesses may be made from any good quality 75-ohm coaxial cable such as RG-6/U and Jerrold
Model F-659 (pat.pend.) adjustable coaxial connectors, Jerrold Model 1596A two-way or Model 1597 four-
way splitters are recommended. These should be used with Model HB-1 outdoor housings for weather
protection. Instructions for use are supplied with each splitter. Consult your Jerrold dealer. Each leg of the
harness should be as short as and directly routed as practical with no sharp bends, length is not critical.
However, the pairs of input cables for each 1596A splitter or pair of splitters must be of equal length; the
four input cables for Model 1597 splitters must also be of equal length.
