What was the area/environment you were flying in and experienced poor range? This can have a dramatic detrimental effect.
Here’s an example that will go against most people’s thinking but I quite often use the linear polarised antennas that come with VTX’s and RX’ers. The reason being I usually fly in wide open spaces where multi-path is not a real issue. These antennas that most people throw away actually have a higher gain than the commonly used circular polarised antennas. I’ve happily flown out past 1km on 25mW using a dipole on both the receiver and transmitter with minimal breakup.
However if I were to use the same antennas in a built up area I think I’d be lucky to get further than 100m without loosing video as a linear antenna is not as effective as a circular antenna at rejecting multi-path signals.
My default antenna setup is a Raptor Omni from Menace RC and a Triple Feed Patch, which is an opensource design, I picked up off Amazon. These seem to work best with the receiver I have in my goggles.
A couple of things to check.
If you are using circular antennas ensure they are both the same polarity. I’ve made this mistake myself especially with antennas that look very much alike at first glance.
How do you select the channel on your goggles? If you just scan for your signal there’s a very high likelihood that you’re tuned to the wrong band. As an example I generally use Fatshark channel 8 (5880MHz), but if I scan for that channel it invariably stops on E5 (5895MHz) because the signal is so strong when I’m close to the transmitter. If I were to fly without correcting for this error my flight would be very short before I go blind.
