A spring-loaded device is installed into a node housing at a predetermined location. The predetermined location is selected to correspond to another predetermined location into which a stinger may be installed. These predetermined locations on the node housing are selected to further correspond to a predetermined internal location of an RF interface connector. A conducting pin of the RF interface extends through a dielectric between a nail head shaped end, which provides electrical connection with the stinger projection, and an end soldered to a PCB of the amplifier. The amplifier may be installed and the node housing closed before the stinger and spring-loaded device are installed into the housing. This facilitates installation of the stinger into the housing without having to open the housing and remove the amplifier. External threads on the spring-loaded device facilitate installation thereof, but a unique torque is not required therefor.
