Simple Jumper Feed Line Choke Optimized for 14-30 MHz

The simplest, most cost effective feed line choke is a ferrite ring installed as shown in the picture (at the antenna feed point) to stop feed line radiation or at the radio end of the coax to suppress common mode coax noise current on the coax braid.

Great choke for log periodics, HF beams, CB antennas and others in 14-30 MHz range

Improves antenna pattern by preventing your dipole from becoming a tripole

Suppresses pesky coax braid radiation and RFI

Reduces coax braid common mode current up to -40 dB ( 6 "S" units) on receive

Use one choke for each antenna feed line

Add a double female barrel connector to act as an "extension" of the existing coax.

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.
