My ham-radio side found this article fascinating…
In this short paper I will attempt to take a practical approach to demonstrate the problems associated with non constant impedance RF connectors. Of particular interest is the now inappropriately named UHF type connector, known more commonly as the PL-259 (Male) and SO-239 (Female). The results gained here are primarily aimed at supplying fellow radio amateurs with information that is not readily available. Characterisation will take place at frequencies around 146 MHz and the at UHF frequency of 438 MHz, where in actual fact this type of connector is not recommended for use.
