This low frequency antenna is used to obtain electric field measurements from 20Hz to 50kHz and was especially designed for Power Line Measurement Testing. PMA-11 is used in conjunction with the EMC-11/ESS (item 104/121)or other low frequency receivers. The PMA-11 gives measurements of AF noise emanations from DC power lines and other environments of high ELF “E” field signals. The MIL standards are IEEE Std. 368-1977- Section 9, Probe Wire Method and IEEE Std. 644-1979. This antenna can be mounted on a tripod and comes with a counterpoise and handbook.
