SpiroNet 5.8Ghz Mini Patch

We are all familiar with the performance of the SpiroNet Patch antennas used for the past few years for performace FPV flying. Recently, keeping the FPV racers in mind, ImmersionRC has introduced a set of much smaller form factor, only 8db patch antennas.


The 8dBi Right-Hand and Left-Hand Circular Polarized Patch antennas, pictures below have been custom designed for the FPV market. Their size makes it Ideal for head-mounting on a set of FatShark Goggles. Much wider beam than its 13dBi  previous version cousin, with easily double the range of a standard SpiroNET CP antennas.

These 5.8GHz Circular Polarized patch antennas were designed, with no expense spared, to be light enough for mounting directly onto an LCD monitor or any headset, or directly onto the front of one of an Immersion RC Uno 5.8Ghz, or Immersion RC Duo 5.8Ghz receivers.

These antennas were precision manufactured with very tight tolerances, *each antenna* is 100% tested on a professional antenna tester (Rhode & Schwartz) to ensure maximum range and performance. The antennas are SMA male connector compatible with all FatShark/ImmersionRC 5.8GHz products sold to date.
