Antenna Experts a leading manufacturer & exporter of world highest performance military grade dual arm archimedean cavity backed spiral antenna. Antenna Experts also offer world shortest lead-time in its military cavity backed spiral antenna range of products. We are also known for design and supply customized version of cavity backed spiral antenna along with customized mounting option and customized color option.

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.

AE 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.

High gain 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 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.

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.

AE AS-1000-3000 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 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

MIl-STD AS-800-6000 uses extended coaxial stubs technique to provide constant 3+ dBi gain over entire 800-6000 MHz frequency band while maintaining the wider beam-width. This cavity backed 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.

Military Grade AS-500-4000 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 radiationsAntenna Experts AS-500-4000 uses extended coaxial stubs technique to provide constant 3+ dBi gain over entire 500-4000 MHz frequency band while maintaining the wider beam-width. This cavity backed 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.

Antenna Experts AS-300-6000 uses extended coaxial stubs technique to provide constant 3+ dBi gain over entire 300-6000 MHz frequency band while maintaining the wider beam-width. This cavity backed 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 LHP or RHCP cavity backed 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.

All the cavity backed dual arm archimedean 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. Cavity Backed 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.
