Resistance is the load in a DC circuit.

I think impedance has a different affect at different frequencies.....

Please correct me if I got all my theory wrong.

Simply put, impedance is frequency dependent, resistance is not.
Thats why it is hard to specify a resistance or impedance range for a
tuner. Our antennas are frequency dependent because a 50 ohm match
is required no matter what frequency we transmit.
