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
improvement 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.
