摘要：
The present invention improves measurement of the formation induction response in the presence of the primary magnetic field generated by a logging tool's transmitter. A structure is provided having a new combination of electrical and mechanical design features which provide logging tool for internal calibration and checking of antenna performance and characteristics before during and after well logging operations.
