I will give you that.  but if you use them with 9913 and larger they
work fine.   For smaller cables i use harbor industries RG 142 and RG
400.  i have had no problems with these cables. in fact i just made 6
phasing lines for a 6 meter duplexer out of RG 142.

well how much power are you running?  if properly tightened they are
usable to the legal limit.
