Antenna Experts cavity backed dual arm archimedean spiral antenna uses 6063T6 ultra corrosion resistant architectural anodized aluminum alloy and designed to provide wideband directional transmission/reception of radio signals. The circular polarized spiral antennas are supplied with powder coating finish to protect the antenna further from severe environmental conditions.
Antenna Experts Cavity backed spiral antennas are highly suitable where circularly polarized signals are required with ultra wide bandwidth. Both left hand circular polarization (LHCP) and right hand circular polarization (RHCP) are available. The cavity backed dual arm archimedean spiral antennas are frequency independent antenna and the spiral antennas are weather protected suitable for outdoors use in applications requiring circularly polarized RF radiations.
Antenna Experts spiral antennas uses extended coaxial stubs technique and designed to provide world highest performance spiral antenna with 6+ dBic gain over the specified frequency band while maintaining the wider beam-width. The cavity backed spiral antennas are highly suitable for transmission, reception, monitoring, scanning, ECM, surveillance, signal intelligence (SIGINT), direction finding (DF), telemetry and airborne applications due to its ultra broad band design feature.
Antenna Experts AS-1000-3000 cavity backed dual arm archimedean spiral antenna use 6063T6 ultra corrosion resistant architectural anodized aluminum alloy and designed to provide wideband directional transmission/reception of radio signals from 1000-3000 MHz bands. The antenna is supplied with powder coating finish to protect the antenna further from severe environmental conditions. Both left hand circular polarization (LHCP) and right hand circular polarization (RHCP) are available.

The LHP or RHCP spiral antennas are sealed in an aluminum cavity and is highly immune to noise. Matching circuit of spiral antennas are housed inside the main body of the antenna. A special mounting hardware to mount the spiral antenna on vertical pole having outer diameter of 38-52mm (1.5"-2"). Higher diameter mounting bracket including any customized mounting can be supplied on request.
Spiral antenna N-Female termination is fixed on top of the antenna body for easy connectivity. Other termination like SMA/BNC/TNC can be supplied on request.
All spiral antennas are light weight, broadband and rugged spiral antennas, supplied with Nylon plastic cover to protect the antenna from environment. The spiral antenna is designed to perform with much higher efficiency than conventional rubber duck antenna.
