FPV-MONITOR-5802D

As FPV monitors go, the 5802D is a great all-rounder and won't break the bank. Offering a fantastic 7-inch LCD display with a 40-channel 5.8GHz diversity receiver, the 5802D is a great package whether you are just starting out in FPV or are an experienced UAV pilot looking for a reliable all in one solution for your video display needs.

Unlike generic LCD displays, the 5802D has been designed for FPV use, so it boasts a 6000cd/m² LED backlit screen which is bright enough to be seen outdoors. Furthermore the built in sunshade keeps glare off the screen and collapses down after use to provide protection during transportation.

Most importantly for FPV users, if the input signal gets weak it does not switch to the dreaded "blue screen" - a problem with many non-FPV monitors whereby if signal strength dips, even for a split second the screen turns blue! When this monitor suffers from a signal interruption it just shows static and hence this feature allows you to fly much further without losing the image and potentially your drone!

The 5802D’s inbuilt dual 5.8GHz receiver matches the screen on its performance. It boasts 40 channels, across five bands making it compatible with most FPV equipment on the market including Fat Shark and ImmersionRC. There’s also has an auto-search function, which is very handy for quickly finding the correct channel for your video transmitter. The inclusion of a 5.8GHz diversity receiver is a real bonus. A diversity receiver is essentially two receivers all in one. In essence, this allows you two mix and match antennas for a solid video link. So it might be that you select a circular polarised omnidirectional antenna, which will provide good reception in all directions in the near field, and a directional high gain patch antenna for long distance flights. The diversity receiver is clever in that it will seamlessly switch between the receiver with the strongest signal.

In addition to the diversity RX, the 5802D has another useful function, namely a DVR. The built in DVR lets you record and play back your flight for you and your mates to enjoy over and over again. More importantly, the DVR could also be a lifesaver for your model. Couple your FPV setup with a OSD (on screen display) and if you lose your model, play back the video to get the GPS coordinates of the crash site. Note that the DVR requires a micro SD card to record footage (supports up to 32GB).

The monitor features an integrated 2000mAh rechargeable battery, which eliminates the need for external batteries and messy wires. The battery life is 2-3 hours and it can be easily recharged from a 12V LiPo battery or 12V power supply.

Finally, the monitor has an AV input port and an AV output port. This means that you can use it as just a monitor and feed it with a signal from a different receiver, or you can use the 5802D's inbuilt diversity receiver and output the signal to another display, for instance FPV goggles.

For the best FPV experience we recommend fixing the monitor to your transmitter using our carbon fibre monitor mount sold separately.

FPV equipment and advice: If you like multicopters, you are more than likely going to like FPV flying. Most people dream of piloting an aircraft for real, well with an FPV setup you can actually place yourself in the cockpit (well sort off)! FPV stands for First Person View – it’s achieved by mounting a camera on your multirotor and broadcasting a live video feed so that the pilot on the ground sees the flight from the aircraft’s view. 

When it comes to selecting FPV TX / RX equipment you will soon discover that there is a huge selection to choose from. However, a word of warning; not all of it will be legal to operate in the UK. Only certain frequencies are freely available to use and furthermore there are constraints on transmission power levels. 2.4Ghz video equipment is legal, however most radio control equipment utilizes the 2.4Ghz spectrum and consequently when used together there will be interference. This leaves only one credible option, the 5.8Ghz band, which incidentally is a very clean band due to the low amount of other users. The drawback is its poor penetrative ability; buildings and even trees can have an adverse effect on the signal strength. This means it’s advisable to use it for line of sight (LOS) flying only.

This brings us onto power constraints. In the UK, you are limited 10mw of transmission power on 2.4Ghz and 25mw on 5.8Ghz. Contrary to popular belief, an amateur radio license (HAM) does not exempt you from the power restrictions for airborne use. While you may have seen transmitters with higher power ratings - 200mw is popular, these are not legal to operate in the UK for FPV. You might be wondering why the power level matters anyway? Well, more power gives greater range. However, it’s not that simple; to double the range you have to quadruple the power! Therefore simply buying a very powerful TX to achieve great range is not an especially effective or legal solution.

The best way to achieve greater range is by selecting appropriate antennas. There are a variety of different types; each designed to work slightly differently, for different purposes. Therefore, in order to make the best selection you need to understand how they work.

Most transmitters / receivers come with an omnidirectional, 2.14dbi gain “Rubber Duck” antenna as standard. The key terms to understand here are omnidirectional and gain. Omnidirectional refers to the radiation (or received) pattern of the antenna. Gain on the other hand refers to the antenna’s directivity. To better understand, you can make an analogy with different light sources. If you have a light bulb out in the open, the light will go in every direction, but it will not go very far (this is your omnidirectional low gain antenna). If you take that light bulb and put a reflector behind it, the light will be directed more brightly and much further but in a narrower beam (this like a directional high gain antenna). Radio power works in the same way, you will never get "extra" power from an antenna, but you can direct the radio power where you need it, and it will be many times stronger.

The best thing about increasing the gain of your receiver antenna is the effect it has on your range. For example, if you were to replace your standard 2.14dbi omni antenna with a 17dbi helical antenna you increased your receiver dbi by ~15dbi. 15dbi divided by 3 gives us 5 times the range you think. Well no, 3dbi gain doubles your distance; another 3dbi on top doubles your new distance. So by increasing the gain from 2dbi to 17dbi actually increases the range by 32x its original distance! All this without increasing the TX power at all!

Because high gain directional antennas work by taking power away from some areas, and focusing it in other directions, they need to be aimed,  otherwise your multirotor will fly into weak spots and your video link will be lost. Remember that the higher the gain, the narrower the beam of radiation and hence the greater need for precise aiming.

If the multirotor is far away from you, aiming will be easy, as its position in the sky will change slowly. If it’s close, it is much harder to keep the antenna aimed. The solution is a diversity system. A diversity receiver has multiple video antennas and automatically chooses which antenna is receiving the best signal at any moment. This allows you to have the best of both worlds; you can have a long range directional antenna that you aim when your multirotor is far away (for example a high gain helical antenna), and also a omnidirectional antenna that only works close, but does not need to be aimed for instance a low gain skew planar wheel antenna).

If it are still stuck, then watch this video - it's an excellent layperson's guide to understanding the relationship between range and gain.

If you want a more in detailed explanation watch this video - it will help you understand polarization and also select an appropriate antenna.
