is not necessary. Ideally, select an antenna height and the 7170 IP-Link Transceiver
location that will use less than 50 feet of coax. If you must exceed 50 feet absolutely do
not exceed 100 feet unless you use a lower loss cable than provided with the standard
system. AES provides a Belden 9913 or equivalent which is a lower loss cable than
standard RG-8/U. 9913 is specified as about 3 dB per 100 feet at 400 MHz, which means
a loss of 50% of power in 100 feet of coax.
1- Terminate the 9913 N-Type connectors at the coax ends that connect to the
antenna, and the surge suppressor, (if applicable, make sure it faces the right
direction) and to the 7170 IP-Link Transceiver. AES pre-installs one connector
on the provided spool of coax. Route or pull your coax such that this connector
connects to the base of the antenna if possible.
2- Run the ground cable from surge suppressor to a suitable earth ground in
accordance with the local building codes.
Figure E – Crimp Style N Connector
Installation of Crimp Style N-Type connectors:
Step 1 Strip cable jacket, braid, and dielectric to dimensions shown. All cuts are to be
sharp and square. Important: Do not nick braid, dielectric, and center conductor.
Tinning of center conductor is not necessary if contact is to be crimped. For solder
method, tin center conductor avoiding excessive heat.
Step 2 Slide outer ferrule onto cable as shown. Flare slightly end of cable braid as
shown to facilitate insertion of inner ferrule. Important: Do not comb out braid. Place
contact on cable center conductor so it butts against cable dielectric. Center conductor
should be visible through inspection hole in contact. Crimp or solder contact in place as
follows:
Crimp Method: Use Die Set Cavity for contact indicated in table above.
