Surge protection or lightning protection? I expect your connection will have enough insulation to protect against surges. Any metal armor or support wire isn't going to be directly connected to your circuit. Lightning is another matter. If this is an aerial cable it may be exposed to lightning and lightning could travel on the cable even if it was non-metallic. ************************************************************************ * ==> QUICK LIST-COMMAND REFERENCE - Put the following commands in <== * ==> the body of an email & send 'em to: [EMAIL PROTECTED] <== * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?
