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 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.
