SUPER CHOKER™ 160-40 for 160-80-60-40-30 meters

Super Choker™ 16040 uses five FT-240 ferrite toroids with custom made RG-8/213 coax cable pre-assembled with nylon ties on the toroids and PL-259 connectors. The Super Choker™ works well in reducing common mode current in our 1.5KW station (see case history below). All you need to add are a couple of barrel connectors and tie into you existing coax feed line. Each Super-Choker is custom made due to the high number of turns required to get the high choking impedance. Available in 52 ohm or 75 ohm cable.

Typical choking impedance over the 160-40 meter frequency range is shown in the graph below:
