APPENDIX B

PATTON MODEL 1009 CABLE RECOMMENDATIONS

The Patton Model 1009 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 1009 please keep the

following guidelines in mind:

• 

Always use twisted pair wire—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 

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
