 Loop antenna substitute(s)

Does anyone here have any experience substituting a ferrite loopstick for a built-in loop antenna? Specifically, I'd like to know how the correct ferrite loopstick is chosen and wired up. I have no particular AC-DC receiver in mind, but I've had the problem of a definitely bad, even missing, loop antenna, and wishing to replace it with something else.

To replace the loop with a ferrite "loopstick" you would probably need to calculate the number of turns for the correct inductance. However it is simple enough to make a new "loop".

I would think any loop should work, as most are designed for the broadcast band. So the inductance shouldn't be a problem, however things might change if the tuning capacitor is a different value from the norm, which is usually 365 mmfd. JMHO
try it and see what happens I dont think any harm would be done as there is normaly just the microvolts on the antenna.
Another thought would be for the old radios that only use outside antennas a loop antenna may work, test that and see.
