MEDIUM ALTITUDE ORBITAn orbit from 2,000 to 12,000 miles above the earth. The rotation rate of the earth and satellite are quite different, and the satellite moves quickly across the sky [17]. |
MEDIUM FREQUENCYThe band of frequencies from 300 kHz to 3 MHz [17]. |
MEGAA prefix meaning one million; also MEG [1]. |
MEGGERCommon name for a megohmmeter [3] [16]. |
MEGOHMMETERA meter that measures very large values of resistance; usually used to check for insulation breakdown in wires [3]. |
METALLIC ARMORA protective covering for wires or cables. Made as a woven wire braid, metal tape, or interlocking metal cover. Made from steel, copper, bronze, or aluminum [4]. |
METALLIC INSULATORA shorted quarter-wave section of transmission line [11]. |
METALLIC RECTIFIERAlso known as a DRY-DISC RECTIFIER. A metal-to-semiconductor, large- area, contact device in which a semiconductor is sandwiched between two metal plates. This asymmetrical construction permits current to flow more readily in one direction than the other [7]. |
METERA device used to measure a specific quantity, such as current, voltage, or frequency [3]. |
METER MOVEMENTThe part of the meter that moves to indicate some value [3] [16]. |
