Overview

DX Engineering Flanged Feedpoint Connectors

DX Engineering Flanged Feedpoint Connectors provide a direct transition from coaxial cable to feedpoint for Yagi, Loop Fed Arrays (LFA), Rotatable Dipoles and other antennas that do not have a coaxial connector. The worry of failed weatherproofing at the end of a stripped coax is eliminated for the 50 ohm beam or loop antenna feedpoint with stud terminals. Flanged Feedpoint Connectors allow direct connection of a PL-259 or N male terminated coaxial cable. Only this Flanged version (FFPC) can be mounted using the optional bracket, Flanged Feedpoint Connector Mount (FFPM) and an optional studded band clamp or other clamp of choice.

Two connector types are available in three versions:
DXE-FFPC-SO239ZD UHF Female with 11 inch leads and color-coded heat shrink
DXE-FFPC-SO239 UHF Female with 4 inch leads and color-coded heat shrink
DXE-FFPC-N Type N with 4 inch leads and color-coded heat shrink

Each Flanged Feedpoint Connector (FFPC) features silver-soldered solid tinned-copper 12 AWG wire leads to the silver-plated connector, which is epoxy potted into a plastic housing, 1.573 inch square and 0.787 inch deep, for a weather-sealed direct feedpoint connection. Each lead has color-coded heat shrink; Red is Center and Black is Shield. Additional weatherproofing should be applied to the male-female connector junction, as recommended. DX Engineering Flanged Feedpoint Connectors two wire leads are about 4 in. each, or 11 in. each for the ZD version. A longer length of wire can be soldered to these tinned wires, if required, but keep in mind that increasing connection spacing drives up feedpoint impedance, which could increase the possibility of mismatch on an antenna that has a 50 ohm feedpoint.

Flanged Feedpoint Connectors are ideal for phased antenna pairs or multiples, on which a coaxial cable ferrite RF bead choke is desired at the feedpoint, in place of a traditional enclosure balun. The top performing 40-bead DXE-FBC Ferrite Bead Choke fits on 0.405 in. diameter coax cable, like RG-213U and RG-8U, prior to connector installation. For the 50 ohm beam or loop antenna feedpoint with stud terminals, the DXE-FFPC-SO239, DXE-FFPM and DXE-FBC are THE perfect combination of feedpoint connection, mounting and RF choke.
