APPENDIX B
PATTON MODEL 1000 CABLE RECOMMENDATIONS
The Patton Model 1000 operates at frequencies of 20kHz or less and has been performance tested by Patton technicians using twisted- pair cable with the following characteristics:
Wire Gauge | Capacitance | Resistance |
19 AWG/.9mm | 83nf/mi or 15.72 pf/ft. | .0163 Ohms/ft. |
22 AWG/.6mm | 83nf/mi or 15.72 pf/ft. | .0326 Ohms/ft. |
24 AWG/.5mm | 83nf/mi or 15.72 pf/ft. | .05165 Ohms/ft. |
To gain optimum performance from the Model 1000, please keep the following guidelines in mind:
•Always use twisted pair
•Use twisted pair wire with a capacitance of 20pf/ft or less.
•Avoid twisted pair wire thinner than 26 AWG (i.e. avoid higher AWG numbers than 26)
•Use of twisted pair with a resistance greater than the above specifications may cause a reduction in maximum distance obtainable. Functionality should not be affected.
•Environmental factors too numerous to mention can affect the maximum distances obtainable at a particular site. Use “maximum distance” figures as a general guideline only.
