ImmersionRC 5.8ghz 600mw
ImmersionRC has a reputation of premium brand in FPV world. Its 5.8Ghz 600mw video and audio transmitter is welcomed by community as nice addition to 5.8Ghz FatShark compatible range transmitter.
One of the main reasons why 5.8Ghz became so popular in FPV crowd is because antennas are really small and easy to transport.
Having long range equipment is one thing, but being able to just pickup your goggles with integrated AV receiver, your FPV model and go fly in a minute is proving to be very useful when the schedule is tight,
and that's where the 5.8Ghz equipment jumps in.
Other important fact is that 5.8Ghz does not interfere with 2.4Ghz RC which became de facto standard today.
AV on 2.4Ghz is proven to be problem with RC on same spectrum range, but so is 1.2-1.3Ghz with it's first harmonic right at the 2.4Ghz part of the spectrum.
There are several manufacturers today producing 5.8Ghz equipment from which Boscam and FatShark stand out and unfortunately equipment from these two is not interchangeable
due to different channel layout. FatShark is producing 5.8Ghz receiver modules for their modular goggles and ImmersionRC 5.8Ghz 600mw is welcomed as great addition.
So far according to community feedback this ImmersionRC proved to be up to the challenge but with the price on a high side, as is the case with all ImmersionRC, you are paying the brand too.
All of you having an eye on a 5.8Ghz FPV equipment should be aware of the downsides of this range too. Higher the frequency, higher the throughput, but the "penetration".
Lower frequencies tend to "bend" around the obstacles a little better improving in overall reception quality. If you are about to invest in one of the key points of FPV, safe range,
and buy yourself LRS RC (Long Range System RC) operating at 433Mhz (or similar) range, you should consider 2.4Ghz and 1.2-1.3Ghz equipment too.
If your plan is to upgrade from 2.4Ghz RC to LRS later on, 1.2Ghz is also the option worth thinking about, with low-pass filters blocking everything above 1.3Ghz,
which are simple add-on and can easily be removed later.
