Terrestrial Microwave Antenna NomenclatureAndrew uses an alphanumeric numbering system for identification and ordering of terrestrial microwave antennas. Andrew type numbers describe antenna type, size and operating frequency band. The system is known worldwide, and many governments, PTTs and OEMs use Andrew terminology such as HSX type performance to specify antennas within their equipment procurement documents. Example:

1HSX PL KP

1. Antenna Type. The prefix is one, two, three or four letters that describe the antenna type. X within the prefix indicates dual-polarized operation. For Standard Antennas, L indicates low VSWR antennas operating with: Coaxial feed systems of 1.10 (26.4) RL or better Waveguide feed systems of 1.06 (30.7) RL or better.Prefix KP_F, KPR_F MKP P, PX, P_F PL, PL_F, PXL, PXL_F FP, FP_F, FPX FPHP HP, HP_F, HPX HSX UHP, UHX, UHP_F UMX HDX, HDH, HDV PDV, PDH KPR PAR, PARX LB, LBX Antenna Type or Description Knockdown GRIDPAK Parabolic Mini Knockdown GRIDPAK Parabolic Standard Parabolic-Unshielded Standard Parabolic, Low VSWR-Unshielded Standard Focal Plane Parabolic-Unshielded Focal Plane High Performance High Performance Parabolic-Shielded High Performance Super High Cross Polarization Discrimination-Parabolic Ultra High Performance Parabolic Ultra High Performance Multiband Parabolic High Performance Dual Beam-Parabolic Standard Dual Beam Angle Diversity Knockdown GRIDPAK Parabolic-Rural Telephony Parabolic Antenna for Relocation-Category A Low Back Lobe

2. Antenna Size. The number indicates antenna diameter in feet. 3. Pressurization. Antennas having an F following the antenna size include a foam-dielectric feed and do not require pressurization. All other antennas have air-dielectric feeds and require pressurization. See pages 242-271 for pressurization equipment. 4. Frequency Band. The numbers following the hyphen are an abbreviated designation for the operating frequency band. For example:Abbreviation 19 59 107 Frequency Band 1.9 - 2.3 GHz 5.925 - 6.425 GHz 10.70 - 11.70

5. Wide band. A W following the frequency band designator indicates wide band operation for special applications. For example: PL12-71 indicates the frequency band 7.125-7.750 GHz PL12-71W indicates the frequency band 7.100-8.500 GHz

Antenna TypesShielded AntennasShielded antennas include a low-VSWR feed, painted reflector and shield with RF absorber, a planar radome and a mount for attachment to a vertical pipe. This series of antennas provides excellent radiation characteristics, rugged construction and high environmental survivability. Special environmental versions are available for the most difficult system locations. Many are also available with one or two-piece reflectors for efficient and less costly shipping.

Ultra Series

Ultra High Performance Antennas UHX and UHP Series antennas provide high gain, low VSWR and superior radiation pattern performance for easier frequency coordination. They minimize frequency congestion problems because of a highly efficient beam-forming feed and superior pattern performance. UHX Series feature dual polarization. UHP Series are a single polarized version.

High Performance Series

Ultra Multiband Antennas UMX Series antennas provide simultaneous dual-band, dual-polarized (4-port) operation in various frequency bands. These antennas can save considerable cost by reducing the installation expense and the amount of equipment required on systems with multiple frequency requirements. UMX antennas allow easy single to multiband transition without compromising high performance.

High Performance Antennas HP and HPX Series antennas feature high performance at low lifetime cost. They are mechanically similar to the UHX ultra high performance antennas, except most models have feeds which do not include the beam-forming feature. HPX Series feature dual polarization; HP Series are a single polarized version.

Antenna Types

HSX Series Antennas - High XPD Microwave Antennas HSX Series antennas are high performance antennas which feature very high cross polarization discrimination (XPD) in both the azimuth and elevation planes. The guaranteed XPD for these antennas is 40 dB. These antennas are suitable for high capacity digital systems, utilizing transmission schemes such as Synchronous Digital Hierarchy (SDH). This performance is achieved through the use of an antenna feed horn with a unique illuminator ring design and strict quality control measures in the manufacture of these feeds. The cross polarization characteristics close to the boresight of the antenna are shown in the figure below. These values apply for antennas up to the 11 GHz frequency band. For antennas at frequency bands higher than 11 GHz, the XPD is greater than 36 dB within the circular -1 dB co-polar contour and greater than 30 dB elsewhere. The HSX Series antennas are available for frequency bands from 3.4 to 18 GHz.HSX Antennas 2-Dimensional Cross-Polar Characteristics Elevation + 1.5 Degrees Elevation Keyhole specifications for XPD
