Hey Matt, easy on the coffee, your knocking these videos out at a rapid rate, I cannot keep up man!
Hey Jon, as of this evening, I am still 17 videos in front of myself! Matt
@@RagTheNutsOff 😱omg
Miss your videos Matt! Hope you're loving life and still flying!
Hi mat would be rear to see a video “suggesting” what the options are for ground receivers as 1.2video gear hasn’t been developed for quite some time due to lack of popularity and a lot of the old products are now nearly impossible to get. Cheers
Try Ali Express for a Lawmate VRX.....Get the best.
Who said ever you didn't like blowing sh!t up Matt. Anyway, I must try this vtx sometime. All the best. Long Range Tony (UAVFutures)
Oh hai Tony! The antenna is a bit crap, but works. The Tx unit power isnt far off what they state too. Happy flying Matt
Greetings, good video. I want to know how to get sound, according to specifications it has a built-in microphone. Thanks
Howdy, No idea, I have never used audio for FPV, ever, in +5 years. Matt
The TrueRC side feed RHCP pagoda style 1.3ghz antennas are on sale from TrueRC for about $10 US... which is amazing if your looking for a 1.3ghz antenna that can be fit on a small model
Dang, great find! Ordered two!
@@t413com Haha me too! Im just getting into the 1.2ghz band and i couldnt believe those antennas were cheaper than budget 5.8ghz antennas.. might go order a few more right now if theyre still available
Just be aware they are tuned to 1280 and 1258. Outside of this range you will have issues, along with issues with cheap 200mW VTX and those antennas. And.... a dipole is lighter and more easily fitted into a much smaller model, say a Dart 250g for example rather than this, which even V2 is pretty big. Fine ina larger model though, Matt
Hi Matt, will you do a proper range/penetration test?
Hey Alex, sadly due to the legality of actually powering such a module on in the UK, thats not something I could do. But it would be fair to assume that it would be fine 5 fields away, below the hedge line. with clovers or 20 miles away with a dipole. Loads of vids on TH-cam that can demonstrate this for you. Matt
what about the receiver? any combo?
Nice video...How are the antennas placed?
Funny, I just ordered this VTX and the matching VRX module but I opted to add the VAS Bluebeam RHCP antenna pair
Hey Allan, hopefully Matek are sending the receiver module at some point too! Matt
Of course you have never flown it. Having said that, how does it behave with our popular sub ghz radio link, such as Crossfire?
In my experience not bad, you just have to give the proper separation between the vtx and the CF receiver also you need to put some separation between the CF transmitter and the video receiver.
Or you can just put a notch filter, though the quality is good.
Can any one help me here just bought one ove these transmitters on here vidio, s fine but no audio straight out ove the box cheers
i bought one but returned it as it was interfering with my crossfire . Think i will stay with the 2.4GHz VTX
Hey Sam, oh how odd. Not heard or experienced any issues with my XF. Matt
Odd, it doesn't affect my R9M reciever...lol.
@@RagTheNutsOff im running into the same issue Gal Kremer and Paweł Spychalski had with theirs. I was using the sock antenna. what antenna would you recommend .
Hi Matt , I have been using these on my fixed wing models for a while . The pin out for the vcc ground and video is that way I assume because it matches the pin outs on Matek flight controllers for fixed wing . I have been flying well over 5 miles with perfect video signal and that's with the antenna pointed straight up .
Are you referring to the stock antenna? In my experience that is pure garbage.
@@alerx94 yes the stock antenna on the tx but a very high gain Pepperbox antenna for the receiver .
Brian, happy days!
CAN WE USE THIS VTX FOR THE LIVE VIEW THROUGH ANY WIRELESS CAMERA FOR LIVE VIEW ???
Do you recommend any other 1.2-1.3 antenna for the rx that can be mounted in the drone?
Does this interfere with 915mhz RC systems?
Howdy Bruno, some people says it does. That's not the experience I've seen. Matt
Looking at this 🤔
Im curious. Why would Matek include shrink wrap if the TX needs lots of air flow for cooling?
Howdy, good question, to stop electrical shorts? Matt
I think you will find these are illegal in the UK even with a license as soon as they are airborne.
Howdy Dave, purely for informational purposes, hence the note at the beginning about checking local requirements & me not powering it on ; ) Matt
Of course officer :)
Soon to be followed by breathing.. it's tabled in parliament to make that totally illegal also..
Isn't analogue all old hat now? :) A friend was using this back around 2013, the skew aerials are massive but picture quality was good.
@@dj_dazzy You don't need skews on 1280mhz, inefficient....dB loss is huge.
Missing some decent Video Receivers to hook up in ground stations and retransmit via 5GHz to FatStarks. Beside that, this Matek seems to be the only quality solution to receive 'long range' video feed
Yea their kit is very, very good. Matt
This is REALLY FRAGILE! mine broke on an impact where it shouldnt have, it just totally died in a rougher landing
Oh wow! I'm sorry to hear that!
will this be compatible to Partom receiver?not sure if this can be use for LTM protocol for this particular combo. looks similar to SM130T VTX module, advertised as 600mw but when i tested it was 300mw only.
Howdy Brooks, yes it will be. Not sure on all the channels, but will do most of them. These are +600mW, we may have tested one with that Immersion RC power checker. Matt
Pretty decent VTX, I use them. But ditch the antenna straight away and swap for something better.
Howdy Graham, thanks for the feedback, super appreciated 👍, Matt
@@RagTheNutsOff I went ~1mi on 5.8Ghz and thought it was terrible, immediately ordered these Matek 1G3 VTXs.. (turned out I'd left the 5.8vtx on 25mw smh.. but still, never looked back).. I got some weird artefacts with the stock antennas (used on both ends, I also have the 1G3 VRX goggles module), the image seemed dull, and occasionally had some bizzare sparkles on bright edges in the image. As soon as I swapped for some decent TrueRC 1.3 antennas, it cleared right up, and not a smidge of static yet at similar distances, need to push it out there further now.
Yea take it slow and learn the limits of the model. It's a long walk if you screw up 😂
Hey Matt did you plug straight into FC I have the f411 wse and it seems it needs 6v
Howdy fella, yep. Its from 6V, I may have tested one to 5.8V, it was still working after that. Matt
@@RagTheNutsOff is there a jumper non the FC to give it 6v as I cant get any life out of mine
Really curious what the range is like With a crossfire. I would imagine this would satisfy my long range appetite without having to buy a ground station or an expensive DJI setup. Anyone test The range/video quality?
Howdy Chris, Yeo this would do. Just search for long range flight on TH-cam. Chances are they are using 1.2 video. Matt
Yep, although Trappy / TBS folks all usually fly 2.4ghz analog VTx's which gets great range (outside of urban areas)
Thanks guys!
Hey Matt, any need for a notch filter to keep from interfering with 2.4 signals?
Hey Chris, other people say yes. I have never bothered and not had an issue. Matt
Harmonics can reduce range on 2.4ghz, everyone I know uses 459 or 868Mhz on the model. Others still seem to be ok on 2.4ghz.
I could see where there could be an issue but there is also a basic rule of thumb to not use control frequencies higher than the VTX frequency or you will lose control before you lose the image.
The biggest issue is with GPS signals, actually. Make sure it's as far from your unit as it can be and expect much longer fix times. Also some video cameras get EMI issues with 1.3 like the Caddx Loris.
Like all electronics, if you bang stuff together with little understanding of the physics it is doomed to go wrong or have rubbish results.
More vid,plz
Hows the current backlog of 17 for you? 😱😅😂
I wish it had an RF reduction down to 200mw....Don't need all that RF on this frequency.
I asked them about that a while back, it's not possible with the module they're using. Matt
