CHANGES TO MEASUREMENT ARRANGEMENT FOR TESTS PERFORMED WITH ROD (MONOPOLE) ANTENNA
Radiated emissions tests for frequencies up to 30 MHz per RE102 of MIL-STD 461 areperformed using a 1.04-meter (41-inch) rod antenna, also known, and referred to hereafter, as a monopole antenna. Prior to the release of MIL-STD 461F (Dec. 10, 2007), the measurement arrangement for monopole antennas was as shown Figure 1. As shown, the height of the monopole antenna counterpoise was coincident with the height of the ground plane on (or over) which the Equipment Under Test (EUT) is installed.A bonding strap, typically a piece of sheet metal or aluminum foil having the same approximate width as the counterpoise, would bridge the gap between the EUT ground plane and the counterpoise itself.
