Why And How To Build An Easy RF Choke.

For just a few Dollars to boot... An RF choke can save the day for field radio operations where you do not necessarily control all aspects of your antenna system and common-mode currents can wreck havoc on electronics, and even your fingers! Use an FT-114-31 with six turns of RG-174 or RG-316. You can also use eight turns with an FT-140-43. For more power handling you can use an FT-240-31 or FT-240-43 but I do not know the number of turns (RG-402). Do not ask me about other types of toroids, I don't know, and those are the best suited for the task. The choke is to be placed near the radio...

It is NOTHING BUT a symbol of freedom and independence. It does NOT imply support to any political group. It does NOT imply, represent nor support any ideology with an intent on harming anyone. Freedom means freedom from persecution based on any human trait or belief such as, non exhaustively, race, gender, religion, sexual orientation or nationality. The Radio Prepper channel is a technology and science channel with a focus on preparedness and use of radio technology for disaster relief and small group communications in times of need. It is apolitical and open to anyone sharing the same interests. .
