What’s up guys?! How is the RC flying world treating you this week? Contact me if you have any questions or comment below. This week’s post is on FPV long range antennas, enjoy!
FPV is a pretty sweet technology that allows us to have a birds eye view in the pilot’s seat of our RC aircraft. Now that we can use FPV, we tend to want to fly farther and farther away. To do this, you need, a bigger battery, long range antennas, and enough time to fly!
FPV uses different radio frequencies to transmit and receive data over the air. As a rule of thumb, the lower the frequency, the farther the distance it will reach. The higher the frequency means the less distance it will reach. So why would we ever use higher frequency antennas? Because there are pros and cons to each.
Low frequency pro: Long-distance.
Low frequency cons: Bigger equipment, lower quality video feed.
High frequency pros: High quality video feed, small and lightweight.
High frequency con: Short-distance.
As you can see, higher frequencies tend to be better for FPV. They are small, lightweight, and can provide high quality video. I would think that most people have smaller aircraft, so most people need small FPV gear that their aircraft can handle.
In order to fly farther FPV range, you’ll need to have more powerful equipment. First, I would make sure you have quality antennas. Get the ones that are clover-like and circular. They make it easier to send/receive signal in all directions. Next, I would get a powerful transmitter. They come in 25mw, 200mw, 600mw, 1 or 2w, etc. The higher the mw (milli-watt), the more powerful the signal. You’ll need strong enough transmitters and receivers for both the FPV camera and remote control. You can’t fly out of range with the controller even though your FPV camera is still receiving signal, haha!
If you want to do super far long range FPV, then you’ll definitely need a bigger battery to sustain the flight time. You’ll also need very strong transmitters and receivers to talk back and forth to each other. Lastly, you’ll need a big directional antenna. I’ve seen them setup on tripods pointing in one specific direction, which is where you’ll fly and receive signal. There is a video I saw of a guy who flew FPV super long range, for a couple hours, check it out below!
I hope you’ve enjoyed the blog today! Be sure to check out next week’s article, and always remember, “Altitude is your friend, fly high, and keep ahead of your aircraft.” Goodbye for now!
