Hi There, i build a homebrew Coaxial Bazooka antenna for my AM Airband receiver, antenna is made of RG6 75 Ohm cable, feed line coax is also 75 ohm, but Receiver antenna input is of 50 ohm, so there is impedence mismatch, can you please help on how i can match the impedence using ferrite (TV balun core), or any other solution.
