Overview

DX Engineering Maxi-Core® 20 Feedline Choke and Mount Kits

DX Engineering Maxi-Core® 20 Feedline Choke and Mount Kits, DXE-MC20-FCM, provide current balance and feedline isolation on coaxial cables for all types of HF through 6 meter antennas including verticals, rotatable dipoles, directional beams and Yagi antennas. Intended for 50 ohm feedlines operated at low SWR, this combination of mounting plate bracket and effective 50 ohm RF choke handles full-legal-power-plus and provides higher common mode impedance (CMI) across a greater frequency range than competing feedline choke and line isolators and previous DX Engineering and Comtek models. High CMI across the AM Broadcast band and the HF/6M spectrum is essential to provide sufficient suppression of unwanted transmitted and received RFI/BCI current on the feedline shield exterior. With less noise and interference you will hear and be heard using a DX Engineering Maxi-Core® 20 Feedline Choke and Mount Kits.

DX Engineering Maxi-Core® 20 Feedline Choke and Mount Kits bring new parts together to work on many types of antennas. They provide improved RF isolation and current balance at either end of the feedline and at the feedpoint of a vertical, a beam, rotatable dipole or other antenna feedline. This is a unique perpendicular choke mount that allows a beneficial separation between the ferrite of the choke and the antenna boom or mast, resulting in improved choking performance compared to a choke mounted on metal. The UV black high-strength polymer mounting plate provides additional isolation and holes for different mounting positions for the choke, horizontal or vertical. Stainless steel hardware is included to attach the plate to the stainless steel mounting bracket, which has laser cut holes for one of five optional DX Engineering Saddle Clamps to cover mast or boom sizes from 1 to 2 in. and 2.375 to 3 in. Click "More Detail" for additional information and click Suggested Parts for required optional items including one saddle clamp to fit your mast or boom and coaxial cable assemblies.

Maxi-Core® 20 Feedline Chokes features high quality silver-plated PTFE dielectric SO-239 (UHF female) connectors. The SO-239 connector limits power handling to 5 kW or less at low SWR and reduced power at elevated SWR. These feedline chokes exhibit very low insertion loss and inherently low SWR. They are built into a convenient weather resistant NEMA enclosure with weep holes at all four corners of the "bottom" side of the enclosure, to vent properly when mounted vertically or horizontally for all types of antennas.

Make your antenna play to its potential; reduce RFI and improve reception with DX Engineering Maxi-Core® 20 Feedline Choke and Mount Kits.
