Great choice Tony, you won't regret it. Just do not skimp on the quality of the
connectors. The termination of the shields to the shell is critical as to how
well the overall cable provides S.E. & immunity and isolation, etc. If you have
a minute check out a video I made on youtube about cheap imported crimp on
connectors. Just do a search on my call. I learned my lesson and only buy
connectors from people I trust. 73 es GL
