Helical antennas have an inherent helix in their design. As a result, these antennas radiate RF in travelling waves through a corkscrew pattern. Signals travelling on these circular waves can be carried on any of its axial planes of symmetry. This method of transmission results in a signal that is better at penetrating and bending around objects, making it more resistant to signal degradation from common communication obstacles such as multi-path, phasing, weather and line-of sight.
Available helical antennas can provide continuous coverage from 100 MHz to 6000 MHz (6 GHz) in both left or right hand circular polarization. All helical models can be manufactured in both commercial or military grades.
HE-238 Series Helical Antennas
The HE-238 series antennas are a family of high power, wide-band, helical antennas that operate in the 1.2 to 1.8 GHz range. These heavy-duty antennas will provide years of reliable service in either military or commercial applications.
Antenna orders come with pole-mounting hardware. A motorized dual-mount, which will house up to two HE-238 antennas, is also available. The dual-mount is available in manual and motorized modes. The motorized mount will allow users to reposition the antenna (along azimuth and elevation planes) remotely for remote applications.
These antennas will provide years of trouble-free service in extreme environments and are currently in use by several U.S. military installations in remote locations.
The HE-0238-165-HH is a handheld direction-finding antenna. Used by multiple government entities, this antenna is constructed entirely out of aircraft certified 6061-T6 aluminum and G-10 fiberglass within a 100% sealed radome that will provide many years of quality and reliable service in the field. Previous models have achieved a 2:1 VSWR across the band. Antennas come packaged with shoulder straps and a mounted magnetic compass.
The HE-500-10 is a high-power right-hand circularly polarized (RHCP) communications antenna. The goal in designing this device was to produce an antenna that would be electrically superior and extremely rugged.
These antennas are custom matched from 584 to 876 MHz to achieve a 1.5: 1 VSWR across the band. The final design is a high quality product that will provide years of performance in any environment. Mounting hardware is provided with the HE-500-10 to securely fasten the antenna to a 2” diameter pipepolarized (RHCP) communications antenna. The goal in designing this device was to produce an antenna that would be electrically superior and extremely rugged.
The HE-0580-10 is a high-power, right-hand, circular-polarized (RHCP) heavy duty small antenna that can suit both commercial and military applications. The antenna is constructed entirely of aircraft certified 6061-T6 aluminum and G-10 fiberglass with a copper radiator which is all enclosed in a sealed radome. This will ensure the antenna provides many years of quality service. In addition, these antennas are manually matched to achieve a low 2:1 VSWR across the 5.0 to 6.0 GHz band.
The HE-1000 series antennas are high-power, wide band, severe-duty antennas that can serve in both military and commercial applications. The antennas are constructed entirely of aircraft certified 6061-T6 aluminum with copper radiators all enclosed in 100% sealed radomes.
Multiple HE-1000 antennas have previously been used in arrays to increase beamwidth without sacrificing directivity.
The HE-1000 models are currently in use by several U.S. military installations in remote locations due to the years of proven, trouble-free service that these antennas can provide.
The TMC HC-238-13 antenna helical/horn hybrid for use in high-power L-Band applications. The helical/horn combination provides low side-lobe levels while maintaining a solid gain. The antenna operates from 1.2 to 1.6 GHz making it ideal for use in GPS-related applications.
