You can use any antena designed for frequency band you need to
measure. A piece of wire will work, if close to transmitter.

Someone is using a random signal to interrupt some of the local stations here but they are only on for 5 to 10 minutes max, they will come on, play ads on 88.1 then change to 94.3 then change to 95.1 and do this for about 10 minutes over the entire band.

You don't need MFJ at all.

A receiver with signal strength meter and directional antenna.
Some old models of receivers had an analog meter that was very useful
for some things.

Tune to the frequency and look for direction with max. signal.
Than move your location say 500m left/right, look for direction again.
Wherever the lines cross is the transmitter.
