MWH SERIES
The MWH series waveguide horn antennas are linearly
polarized, have 13 - 17 dB gain, uniform E and H plane patterns,
and low VSWR . They ar e ideal as an accurate and p rac tical
mic r owave antenna gain s tandar d. The p hysi cal dimensions
of each antenna are designed to taper from a standard
waveguide size, through a flared section, into free space w ith
minimal losses. Anechoic chamber and free space
measurements are accurately performed using these horns as
the primary radiators. MWH horns are available with and
w ithout l ow VSWR w av egui de to coaxi al adapter s. Preci sion
Typ e N f em ale or SMA f em ale connectors ar e used f or horn
antennas operating below 18 GHz and Type K connectors are
used for antennas operating above 18 GHz. Coaxial-to-
waveguide adapters for MWH series horn
antennas are detachable and mate to standard
waveguide flange s.

DRG SERIES
The DRG series broadband waveguide horns are
linearly polarized and provide an efficient low cost
means of making broadband measurements. The
ridged horn antennas cover the 200 MHz to 40 GHz
frequency band in overlapping ranges. These
horns are ideally suited for EMC testing, direction
finding, surveillance, antenna gain and pattern
measurements and other applications. Our DRG
series horn antennas show the following
characteristics: high gain, uniform E and H plane
patterns over multi-octave bandwidths, low VSW R
and the advantage of small size and light weight.

DPH, CPH AND QRG SERIES
The DPH and QRG series antennas are the dual pol ari zed counter par ts t o the MWH and DRG series
respectively. These horns are provided with two orthogonally placed connectors capable of receiving
simultaneous vertical and horizontal polarizations. Hybrid/Switch assem blies and remote sw itch contr ol
units are available for selecting RHCP, LHCP, vertical and horizontal polarizations. The DPH series
horns cover the standard waveguide frequency bands and the QRG series horns cover the ridged
waveguide frequency bands.
CPH horns offer the added advantage of a single circularly polarized output. QRG and DPH horns
have coaxial outputs.
