The cavity backed dual arm archimedean spiral antenna model AS-1000-3000 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 cavity backed dual arm archimedean spiral 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 cavity backed dual arm archimedean spiral antenna is a frequency independent antenna and this spiral antenna is weather protected suitable for outdoors use in applications requiring circularly polarized RF radiations. The AS-1000-3000 uses extended coaxial stubs technique to provide constant 3+ dBi gain over entire 1000-3000 MHz frequency band while maintaining the wider beam-width. This cavity backed dual arm archimedean spiral antenna is 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.

The cavity backed dual arm archimedean spiral antenna model AS-800-6000 use 6063T6 ultra corrosion resistant architectural anodized aluminum alloy and designed to provide wideband directional transmission/reception of radio signals from 800-6000 MHz bands. The cavity backed dual arm archimedean spiral 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 cavity backed dual arm archimedean spiral antenna model AS-1000-9000 use 6063T6 ultra corrosion resistant architectural anodized aluminum alloy and designed to provide wideband directional transmission/reception of radio signals from 1000-9000 MHz bands. The cavity backed dual arm archimedean spiral 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 cavity backed dual arm archimedean spiral antennas are frequency independent antenna and the cavity backed spiral antennas are weather protected suitable for outdoors use in applications requiring circularly polarized RF radiations. The cavity backed 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 dual arm archimedean 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. The LHCP cavity backed dual arm archimedean spiral or RHCP dual arm archimedean spiral antennas are sealed in an aluminum cavity and is highly immune to noise. Matching circuit of cavity backed spiral antennas are housed inside the main body of the antenna.

A special mounting hardware to mount the cavity backed dual arm archimedean 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 with the cavity backed spiral antenna.

All the cavity backed dual arm archimedean spiral antennas are light weight, broadband and rugged spiral antennas, supplied with fiberglass plastic cover to protect the antenna from environment. The cavity backed spiral antenna is designed to perform with much higher efficiency than conventional rubber duck antenna.
