Radome for 5.8ghz Stacked Fan Antenna

thingiverse

The fan-style Omni-directional circular polarized antenna for 5.8ghz FPV video systems excels as the most powerful and versatile antenna available. By combining two cloverleaf antennas, dubbed "Fan antennae", it achieves a staggering signal strength increase of more than one-and-a-half times that of individual units. With each Fan antennae boasting a gain of 0.9db, adding just three decibels increases signal power by twice the amount. Based on observed performance gains over standard Omni-directional antennas, this configuration's true gain is likely exceeding 3.5db. Engineered by Hugo and sold under the TrueRC brand name, its long-range capabilities make it an ideal transmitter antenna for my quadcopter operations. The stacked fan-style design comes with some drawbacks however, primarily concerning the potential fragility of solder joints connecting individual blade components at the central axis. Crash landings can put considerable stress on these areas leading to early failures in a damaged state. In a travel case scenario where antennae are jostled against other objects during transportation, delicate copper wiring inside can easily become kinked or bent out of shape. In response I've created a protective cover, also known as a "Radome" casing designed specifically for this fan antenna setup to minimize damage in such scenarios. The used plastic material strikes an optimal balance; neither overly thick which would potentially cause a slight deviation in centre frequency performance, nor thin enough that it might get crushed in the event of an unfortunate crash landing
