Greetings- can someone provide data on their home made choke for connecting
across the output of a 1 KW, 3.5 mhz , transmitter working into 50 ohms. The
so called safety choke to prevent the HV plate voltage from appearing on the
antenna in case of failure of a blocking capacitor. Normally a commercial 2.5
MHY RFC is used. Perhaps something wound on a ferrite rod. Thanks, Jim.


You might try calculating the inductance of a choke that presents about 500 to
1000 ohms of inductive reactance of the transmitter frequency. Use wire that
can handle about 2 to 3 times the plate current of the final, or 2 to 3 times
the HV fuse rating.
The math is left as an exercise for the OP.
