Simple Dipole Feed Line Choke - RG8X - RFI Range: 1-100 MHz
Product Details
MPN: EFFLC-240

Simple Dipole Feed Line Choke for 1/4" coax (1.8-61 MHz)

The simplest, most cost effective feed line choke is a ferrite ring installed as shown in the picture (at the antenna feed point).

Improves antenna pattern by preventing your dipole from becoming a tripole

Prevents pesky coax braid radiation and RFI

for best results use multiple turns through center

Use one choke for each antenna feed line - take a 3 foot piece of G-8X (part# RG8X-3) and wrap 10-12 turns thru center for a good feed line choke.


16:1 Baluns are useful between 750-850 ohm balanced loads where the impedance at the  end of the feed line is 800 ohms (1/2 wavelength feed line), or high impedance feeds for rhombic,  T2FD and traveling wave antennas.

16:1 Ununs are useful between coax and long wires with a load impedance near 800 ohms like a beverage antenna.  Shortwave listener antennas also can benefit with the 16:1 unun and it may provide a better match than 9:1 ununs – this means quieter noise levels and stronger signals so you can hear distance stations easier.
