6. Two pairs of 3/8” CLAMP BLOCKS should be attached to the butts of element #4. If they are not
there, mount them now loosely on the 1/4-20 x 2-1/2” bolts through each butt.
THE DRIVE MAST BRACKET (OPTIONAL) IS MOUNTED LATER IN BETWEEN ELEMENT #4
AND #3. “SPECIAL” OFFSET BEND PHASE LINES ARE REQUIRED HERE TO CLEAR THE
DRIVE MAST BRACKET.
7. Slide a 3/8” PHASE LINE SPACER onto the shortest set of 3/8” diameter phase lines. Now add
(8) 3/8” PHASE LINE SUPPORT INSULATORS. NOTE: THIS SET OF LINES ARE NOT BENT
SYMETRICALLY. CONNECT THE SHORT, STRAIGHT SECTIONS TO ELEMENT #4 and the
longer straight sections to element #3. Center and align these phase lines and tighten the 3/8”
CLAMP BLOCKS at element #4.
8. Element #3 should have two pairs of 3/8” PHASE LINE CLAMP CAPS on the element butts. If
not, then add them now loosely. Continue installing this phase line set using eight (8) 3/8”
PHASE LINE SUPPORT INSULATORS. Center and align the phasing lines and tighten 3/8”
PHASE LINE CLAMP CAPS on element #3.
9. The phasing lines between element #2 and #1 require (8) 3/8” PHASE LINE SUPPORT INSULA-
TORS, two on each line on each side of the crossover. Element #1 should have two pairs of 3/8”
PHASE LINE CLAMP CAPS. Install now if not already on the element butts. Center and align the
phase lies as before and tighten the 3/8” PHASE LINE CLAMP CAPS on both element #2 and
#1. This completes the phasing line installation.
5. Continue adding these 3/16” rod phasing line assemblies until you reach and finish Element #4.
Tighten the 3/16” PHASE LINE CLAMPS on element #4. Note: 3/8” tube phasing lines are used
between element #4 through element #1.
