[Elecraft] Off Topic RG-174

[Don Wilhelm]

Mike,

My chart in the ARRL Handbook says RG-174 has a dielectric breakdown 
voltage of 300 volts RMS.  So in theory, it will handle 1800 watts at an 
SWR = 1.0 (less at higher SWR) - but I would not trust it at much over 
25 watts myself.  I like to see a larger safety factor where 
transmission lines are concerned.  The ohmic losses may be great too, 
that all depends on the length and the SWR.

73,
