Consisting of just 2 components, the Iridium certified & patent pending antenna design is simple in structure and
easy to produce & assemble whether as an embedded antenna or as an externally mounted stubby antenna.

New RHCP Dipole HelicalSmaller, Lighter, Simpler by design!
The new CSA helical antenna turns the use of the quad-helical for Iridium antenna designs on its head.
At 16mm x 15mm HxD, this tiny circularly polarised dipole antenna reveals itself to be a low cost, high performer.

Size Matters
The certified CSA structure will be the basis for a series of standard and innovative antennas designs during 2015 and 2016.
Starting with the 16mm tall CSA we can double the height to 32mm, combining 2 CSA radiators on a single surface, substantially improv-ing low elevation angle gain and efficiency.
The first of these advanced embed-ded models, the CSA X, has been tested extensively and confirms the increased performance.

Key differences. CSA vs traditional quad-helical designs
Electrical - RHCP Dipole vs Quadra-helical • No matching circuits needed• Easy to tune & repeat• High manufacturing yield• Simple design• 2 component design• Direct connection to modem
Mechanical - UFL jumper vs SMA connector• CSA shorter & lighter• Antenna tamper-proof• Housing is machined ertalyte• Very strong in cold and hot weather• Excellent drop-test resistance

Typical Antenna Patterns
LEO satellites networks, by their nature, are constantly moving. Relative to your Iridium set-up, the following are facts:
1. 100% probability 3-4 Iridium satellites visible on the horizon2. These satellites 1200km to 3000km distant from you3. Their angle of elevation will be between 1 and 25 degrees4. < 25% probability one satellite visible from 35°& 90° elevation
So why build complicated helical antennas that radiate power into empty space?
The certified CSA design has enough gain at low angle elevations to be ap-proved the Iridium network, a stacked CSA design has substantially more gain!
