APPENDIX B
PATTON MODEL 1040 CABLE RECOMMENDATIONS
The Patton Model 1040 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 1040, please keep
the following guidelines in mind:
• Alwaysuse twisted pairwire—this is not an option.
• Use twisted pair wire with a capacitance of 20pf/ft or less.
• Avoid twisted pair wire thinner than 26 AWG (i.e. avoid higher
AWGnumbers 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.
