The frequency of a wave cannot come alone. It comes with either signal voltage or current. You need a DEVICE connected to an antenna which picks up a sample of wave power, and has terminals on which you can connect a frequency meter, counter, etc. A pickup coil can be such device, but as its diameter is small compared to the wave length, so the signal power to be used would be small, too. A better choice is a half-wave dipole or a directional antenna.
Some frequency counters can measure signal frequency with only a quarter-wave antenna not very far from the transmitting antenna. A power level like -10 dBm is enough for them to measure.
