Low Observable Antenna Matches Characteristics Of 5/8 Wavelength Whip Antenna

May 18, 2010

FOR APPLICATIONS that require a more compact antenna but still must achieve superior low-angle radiation, a new antenna provides a 3-dB beamwidth horizon to 55 deg. elevation with less than 3 dB azimuth variation. This linear antenna achieves a peak gain of -3 dBil while its rugged construction makes it suitable for extreme environments. The Low Observable antenna is available in diameters ranging from 2.5 in. at ~915 MHz to 11 in. at 150 MHz with a 5/8-to-1.5-in. thickness. It provides a scalable frequency of 136 to +915 MHz. The Low Observable antenna is built to withstand temperatures ranging from -25 to +85C. It is completely groundplane-independent and is well suited for applications like very-high-frequency (VHF) and ultra-high-frequency (UHF) voice data and VHF/UHF LEO satellite systems.
