Immersion Fatshark SpiroNET CP Patch 5.8GHz Antenna (SMA) 13dBi Gain

In one of my previous orders 2007127371, I bough an ImmersionRC 5.8GHz Circular Polarized spiroNet Antenna which is now discontinued. I am planning to buy the Immersion Fatshark SpiroNET CP Patch 5.8GHz Antenna (SMA) 13dBi Gain to use with my existing antenna but I don't know if my antennas are rhcp or lhcp. Can you please help me?
