|4. Coaxial Cable<br />

F Connector<br />

• The 75-ohm, screw-threaded couplers are used with RG-59, RG-6<br />

and RG-11 type coaxial cables.<br />

• It is standard for cable television systems.<br />

• It is simple to install and economical.<br />

• It meets the specifications of CATV/MATV systems.<br />

• A single crimp on the attached ferrule terminates the connector.<br />

Bend Radius<br />

Current military coaxial standards do not specify bend radius; however, various<br />

manufacturers do provide guidance. Check with manufacturers for specifics.<br />

Special care should be taken when pulling a coaxial cable around bends. Using<br />

too much force or too tight of a bend can deform the dielectric and cause a drop<br />

in transmission performance.<br />

Testing<br />

Testing coax performance includes the following:<br />

• Impedance anomaly<br />

• Return loss<br />

• Attenuation or insertion loss<br />

• Signal level<br />

Note: Use a signal strength meter to verify that the right signal level is available<br />

(check installed length and possible damage). Contact your <strong>An</strong>ixter sales<br />

representative to learn more about tools available for testing coax.<br />

CCTV 750–1,000 ft. 1,000–1,500 ft. 1,500–3,000 ft.<br />

Range depends on cable and connector performance, environment, signal frequency,<br />

and transmission and reception equipment.<br />
