Run the Cable to the Grounding Block or NIU

Using the 2-4-4 method described on page 5.4, attach the messenger wire to the hook (or use a messenger wire

clamp). Strip the remaining messenger wire from the coax.

Route the cable from the attachment point to the grounding block or the entry point for the NIU. The path should

follow the architectural details of the residence, running down at the corners and across at beams and seams in

the siding.

Use cable clips to attach the coax to the house. A variety of screw-in or nail-in clips are available for wood and

masonry. Special snap-in clips are available for vinyl and aluminum siding. Never staple coaxial cable. Sta-

pling will deform the dielectric and may damage the shield; in either case, a loss of performance will result and

you will have to replace the cable.

Place your first clip so as to allow for

a small drip loop. Then place the clips

about every 3 feet (1 meter) for verti-

cal runs and no further apart than 18

inches (.5 meters) on horizontal runs.

Make sure you do not kink or bend

the coaxial cable tighter than the rec-

ommended bend diameter (usually

10x its outer diameter - check your

cable specs to be certain). All coax

connections to the grounding block or

splitters must be horizontal.

If connecting to a ground block, pro-

ceed to Section 7. If connecting to an

NIU, proceed to Section 8.
