I'll agree that connecting the coax shield to a low impedance ground will hold the shield near ground potential for a fraction of a wavelength along the coax. At DC and power line frequencies, that will include the full length of the coax in most installations. At 195 MHz (TV CH-10) a full wave length is a bit more than 1.5 meters. Effective grounding of that frequency will extend significantly less than one quarter of that distance from the ground block with a zero impedance connection to a perfect ground.
Please cite some credible sources that can explain how the inductance and capacitance of the coax shield can be selectively ignored.
