DX Engineering Direct Coax Feed Add-On Kits are designed for the Hustler BTV series antennas, which allow for a direct connection with a coaxial cable PL-259 (UHF male) connector. Manufactured from heavy duty stainless steel, these add-on kits allow for a convenient connection from your coaxial cable feed line directly to the base of the Hustler BTV series vertical antennas by adding an mounted SO-239 (UHF female). They can be positioned in any one of three different directions, to accommodate a straight-in or sideways connection from your feed line. If you are looking for a professional and reliable installation, then order a low power or high power (low loss) coaxial jumper cable for connecting your radial plate with a bulkhead connector. DX Engineering Direct Coax Feed Add-On Kits include a laser-cut stainless steel bracket, high quality SO-239 with PTFE insulation, and stainless steel hardware.
