So you’re building a small dual-band Yagi and the instructions tell you to split the coax at the feedpoint. Stop right there. DX Engineering’s Michael Murphy, KI8R, shows you a better solution in the video below from DX Engineering’s YouTube channel.
Using a DX Engineering Flanged Feedpoint Connector and compatible hardware mounted to the boom will save you troubles down the road by keeping your coax connector water-tight. Plus, KI8R shares tips on how to seal all your antenna connectors to keep your coax free from damaging moisture using 3M Temflex 2155 Rubber Splicing Tape and 3M Scotch Super 33 Plus Vinyl Electrical Tape.

More About DX Engineering Flanged Feedpoint Connectors
These handy parts provide a direct transition from the coaxial cable to feedpoint for Yagi, loop-fed arrays, 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.
Choose from three versions of DX Engineering Flanged Feedpoint Connectors:
- DXE-FFPC-SO239ZD: UHF Female with 11-Inch Leads (below)
- DXE-FFPC-SO239: UHF Female with 4-Inch Leads
- DXE-FFPC-N: Type N with 4-Inch Leads
Only flanged versions can be mounted using the DXE-FFPM Feedpoint Connector Mounting Bracket and optional DX Engineering Stainless Mounting Clamps with Studs.
DX Engineering Flanged Feedpoint Connectors feature:
- Silver-soldered solid tinned-copper 12 AWG wire leads to the silver-plated connector, which is epoxy potted into a plastic housing for a weather-sealed direct feedpoint connection
- Color-coded heat shrink (red is center; black is shield)
DX Engineering Flanged Feedpoint Connectors are also 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 balun. DX Engineering’s 40-bead DXE-FBC Ferrite Bead Choke Kit (below) fits on 0.405-inch 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, we recommend using a combination of the DXE-FFPC-SO239 Flanged Feedpoint Connector, DXE-FFPM Mounting Bracket, and DXE-FBC Ferrite Bead Choke Kit.
