[Elecraft] OT: SO-239 Connector Selection

[Ken Kopp]

A word of caution about SO-239 / PL-259's ...

In some connector applications ... particularly power
dividers and other applications that are "impedance-
conscious" ... SO-239 / PL-259" connectors are not 
suitable.

They're -not- 50-ohm connectors.  This is why one usually 
sees Type-N connectors used in these applications.  They 
-are-, by definition, 50-ohm connectors.  I learned this the 
hard way some years ago when I built and sold VHF and 
UHF NBS Yagis with multi-port power dividers.

This may not be an issue with Brett's filters, but I'd stay
with N's or BNC's.  They're also, by definition, 50-ohm
connectors, BTW.   I've specified BNC's for all my ICE
filters, and have them on my K3, watt meters, etc.
