Which UHF...?

[M6TPV]

Hi and hello.  This is my first post here although I am a frequent viewer over on the FPVLab forum.

I have been FPVing for sometime and have a set up that uses 35MHz control and think its about time I ungraded to UHF but I am torn between the various systems out there...

I live in the UK, in Somerset and would like to ask fellow UK FPV'ers what there thoughts are and which system I should go for, at the moment I am toying between EzUHF and Dragon Link. 

Many thanks in advance..

Looks nice, looks proper bash proof, can it be used with such items like Naza Controllers and EzOSDs?

Scherrer system, mentioned above is NOT UK legal (Scherrer only 433 to 440 MHz).

My vote goes to EZUHF - can be UK legal, wide selection of plug & play cables / leads to cameras available.

Why do you need UHF...

You can fly 2.4ghz upto 1.5km or more 2km is possible

I am yet to understand why people need UHF all of a sudden

UHF 459 mhz is the UK Legal Band as well for model aircraft

well if you got a quad and fly low behind trees,buildings and bushes,2.4 wont cut it,UHF will :)

2.4ghz is ok for LOS, short range FPV but if you want to push the envelope you need to look further down the spectrum.

I think what you chose will depend on a) your radio and b) your budget

[MarkLincs]

I'm sorry but 1.5km 2km is not LoS flying nor is short range

500m is short range 1.5 / 2 km medium and then 2km plus is long range ?

be it a quad or a plane

low flying 500m out plus more my 2.4ghz sets never let me down and Trees are not an issue low and behind them either. Its a myth that 2.4 a tree will block the signal totally it might reduce it slightly but certainly does not block it.

As for buildings that depends but you shouldn't be near them any way... only Iron works in a building will really cripple the signal an old stone building will have little effect.

I'm not saying it doesn't work for you :) but in a high RF area 2.4 is pretty ropey.. And it really doesn't like organic things being in the way.

i said trees and bushes..plural :)..not one tree or bush :)
done tons of 1ft low behind bushes and trees and my JR 2.4 just failsafed,rise above 2ft and it comes back,no good to me..Futaba 2.4 probably better but not tried it..

My futaba 2.4ghz, even though quite a few years old but has diversity, will drop signal if I fly low and below the horizon line..... splat!!!

My UHF twitches though doing the same thing.

I have used CahinLinkDare UHF for a while and had some good results with it. However a new RX was ordered, tried to bind and now it is all locked out and will not bind at all!!!!

Got EZUHF now and that is good, plenty of nice distance flying but has glitched now and again. This was on a Futaba 6EX which is old yet still performs fine.

Now have the EZUHF on a Turnigy 9XR so lets see what that brings, hopefully not a crash  :laugh: :laugh:

Don't know if that has helped but at least you have a bit more info.

Don't get me wrong I fly my quad on DSMX but its Naza + GPS so it can RTH on failsafe and I've been out almost 900 meters and I get a bit butt twitchy.. .. However not everyone  is flying something with RTH :).

I've taken my EzUHF equipt wing 3km and it was rock solid :)

wgt40w,

And there's me thinking that my Amateur Radio License that I've held for many many years allows me to transmit digitally on the 433 and 440 bands...... I must be wrong  :)

Yes but you did fly below us... a lot of land between us and the model :)

fine theres a row of trees I often flew between me and my model

JR 2.4ghz... DSM2 ? if yes then thats why you got drop outs and issues
