The 75 ohm specification on an impedance matching transformer is 75 ohms impedance. Not 75 ohms resistance, and cannot be measured with a simple ohm meter which is only capable of measuring DC resistance.
On most antenna systems you will find nothing that measures 75, or 300 ohms DC resistance.
An ohm meter can still be a useful tool for testing coax end to end for continuity, and shorts.
