The standard method of RF feed production within the industry uses injection moulding. This can be a very expensive method if a relatively small amount of RF feeds are needed. This is due to the cost of design and manufacture of a mould template and programming of machinery.
At iSat we use a CNC machining method to produce our RF feeds. This simplifies the design process and eliminates the cost of a mould. Because of this, for small to medium scale manufacturing runs we can beat the cost of most big manufacturers.
RF feed manufacture has been a very successful venture for iSat. We have helped numerous satellite operators to improve the commercial viability of their ‘awkward’ capacity by manufacturing satellite antenna feeds that fit their transponder frequencies exactly.
This can lead to improvements in link efficiency and has often enabled the sale of bandwidth which was previously unsaleable.
Our RF feed production process
- Once we receive the requirements for a feed, we pass them to our RF design engineer. The engineer designs the internal cavities of the feed and RF modelling software.
- Our mechanical design engineer then designs the external dimensions and mechanical parts of the feed, and prepares all of CAD drawings
- We pass our CAD files to our manufacturing partner, who can manufacture the feed in batches with discount based on the quantity of each batch.
- When we receive the feed components we assemble them in the iSat workshop and apply a paint finish if required.
- We test each feed assembly individually for performance and functionality.
- You receive the finished product ready to bolt straight onto your antenna, with individual test results for each feed to prove its performance.
