[Antennas] Splicing Coax

Thu, 13 Jun 2002 17:23:07 -0700

Jan,

My favorite way of doing it is to use a female "N" on one end and a male "N"
on the other.  This provides a very low loss connection than is good through
UHF.

Epending on what variety of coax you are using, this may or may not be a
good solution.  I have migrated to using Times LMR-400 exclusively for a
number of reasons.  The crimp tool for the type "N" connectors is about $85
with the male connectors coming in at a bit over $6.00 and the female
connectors at slightly less than $4.00.

Installation time is about 1 minute per connector.  The pin spacing is
preset so there is none of the problem that we had with the older style of
type "N" connectors where it was quite difficult to get the pin spacing
correct.

I use these connectors and cable from 1.8 mHz. through 5.7 gHz. with
tremendous success and NO problems.

Milt, N5IA
