A test of the inverse-square law, conducted on a 610 m television transmitter in Inverness, Mississippi, measured gravity at five elevations on the WABG tower, and compared these data with the Newtonian predictions using potential theory. The largest observed-minus-model discrepancy, at 493 m above ground, was ({minus}33{plus_minus}30) {mu}Gal (1 {mu}Gal=10{sup {minus}8} ms{sup {minus}2}). These data have since been supplemented with additional gravity data taken on the tower at a higher elevation. The results confirm the predictions of Newtonian gravity, with a discrepancy of (32{plus_minus}32) {mu}Gal at 568 m. The tower experiments, along with current lake experiments, place very tight constraints on any possible non-Newtonian forces. {copyright} {ital 1997} {ital The American Physical Society}
