DESCRIPTION

The EMCO

Model 3121

dipole antenna with its set of

four compensated baluns offers an accurate standard

for precise EMI measurements. This model is an

mprovement of the FCC balun design and performs

close to the theoretically perfect lossless dipole.

With its close to ideal characteristics, the 3121 is well

suited for both EMI testing and site attenuation tests as

described in OST 55 and ANSI C 63.4.

Like all EMCO antennas, each 3121 dipole set is

individually calibrated and shipped with its own factors

as well as a signed Certificate of Conformance. The

result is an antenna with precisely

measured

factors.

Other commercially available antennas supply only

typical or theoretical factors. Accordingly, the EMCO

dipole user need not worry that an error in the antenna

factor will cause measurement errors during EMI testing.

EMCO dipoles are constructed of removable stainless steel

elements and machined and fabricated non-corrosive

metal baluns. A clamp block, delrin support rod and

aluminum mounting base are included in the set. The

aluminum mounting base accepts standard 1 /4 in. x 20

male threads from an EMCO tripod or most other

tripods. All components, including a tape measure, are

mounted in a shock resistant carrying case.

EMCO warrants its dipoles to be free from defects in

material or workmanship for two years. Annual

recalibration is suggested.
