Trying to finalize my FPV shopping list and I'm a bit confused about the antenna set-up.. What is the difference between a Helical and Patch antenna?? They are both directional antennas right? I.e. help with long range.. Is the SpiroNET by ImmersionRC the same thing as a cloverleaf antenna? What's better, IBCrazy Bluebeam, or the SpiroNET? What's the best set of 3 for a diversity Rx monitor? And yes, what is the difference between Helical and Patch?
