[amsat-bb] Re: N-type connectors for LMR-400 Ultraflex

[Edward Cole]

Dave,

I use the RFN-1002-1SI male-N connector with both LMR-400 and 
LMR-400UF.  I have over 20 of them in use in my 2m-eme antenna array.
They also fit Belden-9913 cable (but I do not recommend using 
9913).  No need for any center conductor trimming.

Ordinary N-Male connectors are sized for RG-8/RG-213 coax which has a 
smaller diameter center conductor.  Using them will introduce a small 
impedance "bump" since one must trim LMR cables to fit them.

In 10+ quantities the RFParts connector costs $5.50/ea.  Not that bad 
an increase over the standard N-Male (In fact about the same cost as 
Amphenol N-Male's).
