I've heard several times that RG-58 coax should not be shrink wrapped.  The Lightspeed electronic ignition installation manual specifically states "Do not shrink wrap RG-58".

I cannot find anything that formally states as a general rule that RG-58 should not be shrink wrapped or what problems it creats.  I would like to perform the simple application of clear shrinking lables on co-located coax antenna leads.  Is this acceptable?

Can anyone shed some light on this?

Thanks,

Roger

Roger,



The RG58 insulation is polyethylene. Heating will allow the insulation 

to flow and disturb the geometry of the core element relative to the 

outer braid, changing the coax impedance.

So...don't 

And don't squeeze them with Ty-Wraps either.

Concerning the coax label, how about a nice little label attached to the 

crimped metal collar at the BNC connector ?



FWIW,

Regards,

Gilles
