ImmersionRC Uno5800 vs. Duo5800 FPV receiver comparison

a short comparison between the ImmersionRC Uno5800 and the Duo5800 DIversity Receiver.
As you can see a Diversity Receiver brings you a higher effective FPV range for more safety and fun.

excellent test, just what I needed to see. was about to purchase this thinking that it will improve my video noise. after seeing this, its even worst than what i have set up. thanks for this video!

I appreciate the video.  This test doesn't make sense to me.  The duo is simply two receivers in one unit and then it picks whichever has the best signal.  If everything is using the stock whips then the signal should be the same.  There should be no range increase unless one of the receivers is more sensitive or one receiver has a better antenna.  The whips are linear so unless you had them point slightly off from each other it should give no benefit with polarization and being linear they have no advantage for multipathing. There are two advantages with diversity which is to use a directional and a omni so that you can fly long distance in one direction and then when you come back you can fly behind you for landing (where it switches to the omni) or use two directionals and offset them slightly which broadens the path that you can fly.  I do own the duo5800 v3 and its a great receiver and have easily gone 3.2K on it.  For planes I use two helicals offset and a tracker which eliminates the need for the omni.  For multis a rhcp omni right off the goggles is usually good enough as they don't go out as far.  All with a rhcp spironet on the airframe.  Now I am starting to change my video over to 2.4 and 1.3.  I have an example test of all three uploaded on my channel.

Thanks for sharing this, its very helpful! :)

nice video..can you please recommend for quality battery and a charger for the immersionrc dual reciever...?

Eh, but if the DUO just has two stock antennas in it, where is this extra signal coming from? Does the DUO do more than switch between the two? If all antennas are stock dipole, then wouldn't the DUO switching from one to the other be similar to moving the UNO 2 inches to the right or left?

I always thought a DUO with two stock antennas in vertical would be almost useless; you need to have one omni and one directional to achieve such significant differences. Is that not the case? Is there magic in the DUO?

So, is the Duo really worth the cash?

which chip should I use for fatshark goggles

[nber]

I go 2 miles on spw/spw with a single fatshark goggle rx.. 1.5km wih a 12db antenna is not that great

I want to buy a set of goggles and receivers
