Step 3. Install the four surge suppressors (Line Items 26) just inside the building were the coax cables W1
(Line Item 23) enter the building as illustrated in view “E” of Figure 5.4-1. The surge suppressors,
are mounted to the surge suppressor bracket, Line Item 17), which has been mounted with the 2
remaining lag bolts, and lag bolt anchors (if required).
Step 4. The surge suppressor bracket needs to be attached to the same building ground, view E, that the
antenna mast and power outlet are grounded to. The enclosed ground wire, (Line Item 18), lug,
(Line Item 19) nut and bolt, (Line Items 20 and 21) will allow the attachment of the ground wire
to the surge suppressor bracket
Step 5: Connect the bare cable from the lighting rod to the building ground as illustrated in view “C” and
view “G”.
WARNING
Improper Lightning Rod Grounding Hazard
Ensure the lightening rod is properly grounded before connecting the equipment. Failure to
observe this warning can result in serious injury or death by electrocution.
Step 6. Connect the short (1ft) coax wire W3 from one of the antennas (View “B”) to coax W1 (View “A”)
and secure to the antenna’s crossbars. Repeat for the other 3 antennas.
Step 7. Connect the long coax W1 (30 feet) from the cross bar to one of the lighting arrestors (View “E”).
Repeat for the other 3 long pieces of coaxs
Step 8. Tie wrap the four coax cables and ground wire to the mast.
Step 9. Connect the 6 feet coax W2 to the lighting arrestor.
BEFORE CONNECTING THE W2 COAX TO THE BACK OF THE MXU, VERIFY THE
CENTER CONDUCTOR OF THE COAX IS NOT SHORTED TO OUTER SHELL OF
THE CONNECTOR. REFER TO FIGURE 4.3.2-1

Verify all the coax cables are connected, from the antenna to the last
connector on W3 as shown. NOTE: There are 2 or 4 sets of these
coax cable strings to verified, i.e. no shorts exist.
