Hi Adrian, the Multi-band helical GNSS antenna offered by Emlid works well enough, especially useful for mounting on a drone. I believe it doesn’t quite offer the same performance as some of the alternate survey grade antennas I had mentioned above. Please see this report by another member ( wizprodChristian Grüner on the forum testing a similar helical antenna vs a Swift 500 antenna.
Right tool (antenna) for the right job - Patch versus helical on M2 for ground use
Of course it all depends on what you need for the type of work you do.
