conduit to the antenna.

cable to the lightning suppressor.

building, and route the cable through the building to the TimeSource 3100 Shelf location.

of 4.115 mm (6 AWG) round cable to the two-hole terminal, slide the terminal over two of
the three threaded posts on the lightning suppressor mounting plate, and attach the
terminal to the mounting plate with two KEPS nuts. Use the two posts that allow the least
