I have an AM radio on an aluminum boat. The radio is shielded on
six sides by aluminum. I want to mount an antenna on the boat and
run coax inside and couple the signal to the ferrite rod in the radio.
I'm thinking about an active whip antenna with a 50 ohm output. If I
did this, I would have a coax with 50 source impedance at the radio!
How do I create a 50 ohm load at the radio over the AM band? The radio
has a 2-3/8" x 3/8" ferrite rod.

I would appreciate any other solutions to get a signal to my radio.

Mike,
I didn't do anything but see this and since it didn't work any more,
take the loopstick and some other good parts out of it. A radio my dad left
had an RCA jack taped to the handle. It had about 8 turns of wire wound
around the ferrite loop stick antenna inside the handle. If the "coil
around the whole radio" seems poor, try this. What you do on the other end
of the antenna coax, I can't comment. I have only begun to play with
200-500kHz reception.
