[TenTec] Faraday cage

The only way a Faraday cage around your shack could save your radio 
equipment from the effects of RF would be if every single cable had 
perfectly balanced RF currents so that no cable inside the shack Faraday 
cage radiated any RF, and every piece of equipment (except perhaps the 
one you are trying to protect from RF by shielding and bypassing 
everything else instead of this one piece of equipment) would have to 
have proper shielding and RF bypassing of all leads that entered/exited 
each piece of equipment. If you could not accomplish all of that, the 
Faraday cage would do nothing for you. The Faraday cage could even have 
the effect of increasing the RF problems by virtue of standing wave 
resonances making hot spots in some places at some frequencies. Much 
less effort and expense to properly shield and bypass the piece of 
equipment that has the problem.
