- Design & construction of a high performance L-band reception antenna (e.g. for INMARSAT monitoring)
- Flexible design to allow for multiple mounting options
|A.1||LHCP Helix for offset dish||Mounting off center to get enough clearance towards dish arm|
|A.2||LHCP Helix for prime focus dish||Mounting centric|
|B.1||RHCP Helix for direct reception||Tripod mounted (or other), right hand polarization for direct reception|
Offset dish geometry: red lines show the nominal ray tracing from satellite into the LNB phase center.
An L-band helix including its reflector are much bigger then the standard LNBs and would thus need to be moved slightly above the nominal LNB position. This would result in the green ray tracing which would slightly delude the focus.
