5.8ghz 200mw - Best antennas for range - best channel?

[Nadss]

Hi guys

I have a fpv system which is 5.8ghz 200mw - I am after some better range.

I have cloverleafs on atm which are good, however i NEED more! :)

Plus what is the best channels to fly?

Best antennas ?

cheers guys

Someone did a test and showed that there is a discrepancy in watts depending on what channel you choose, I can't find the link now but there is a specific channel which gives the most output power.

And for range you need a better antenna on your VRX. I suggest the Immersion Spironet Patch antenna. Should be able to go 4-5km with that.

I could do you a 5 turn helical mate, good for a couple of k at very least, also one of my skews attached to your vtx

Dogzilla - that's very interesting, if you could find the channel which is best ill appreciate that alot

Hello, this is Tony from fpvlr.com

with 200mw foxtec unit (same as hk) I am still the record holder.
With a pinwheel on the model and a 16 turn on the rx I did 20km about 1 and a half years ago.

My customers get between 4-7 km with a 4.25 turn helix, and 6-10 km with a 8 turn helix on the same tx with rc305 rx.

the 8 turns is here

and pinwheel is here

this video is of a customer of mine doing 7km with a 4.25 turns + pinwheel
7000m


and this
is of a customer dong 10+km with a 12 turn and a pinwheel
10km part2

One word... WOW... 20km!!

hows the picture when flying?

[FPVSteve]

It is as you see it above, that's a ground recording.

i.e completely shite and like flying through a snow storm.

One thing about the Boscam gear is that they tend to work much better at the very limits of video reception, that is, even though the picture is basically whited out, you might still be able to see enough to fly and the RX is happy when the reception comes and goes.

Whereas with the Immersion kit. the video quality seems to stay better all the way until the limits, at which point it just shits out and it's gone, and once the image is gone I find that the receivers tend to have a hard time locking onto the signal again. They definitely don't like having the reception come and go, I think they lose sync or something. (I have no idea what im talking about... ).

So I would say if you are trying to fly outside of your range at all times the Boscam stuff tends to be a bit better for that. But I'd still go with Immersion every time because up until the image goes it's way way better.

[KondorFPV]

absolutely,
immersion gear has much better picture quality, there is no contest.

with the immersion stuff, I could go 40km with no problems, I will probably set up a plane to show very long 5.8 range.

The best channel is the one with least noise on it. Varies from one location to another.
Just flick through your available channels without your Tx powered and see which one has least interference on it.

actually this guy recorded at 240p, but actual quality in the goggles is better at 640x480.

here you can see a crosshair I made with a a better resolution and also a boscam 200mw

[KondorFPV]

here you can see the same boscam 200mw with a decent camera and 2 pinwheels.

you can watch it at 480... quality of video is more than decent.

Now, if you really want very good live video , there is no match for 1.2 ghz stuff, make sure you watch it at 480p.
Here you can see a 4.25 turn I made + pinwheel.
You see perfect picture up to 17km (please feel free to forward the video, to minute 29 when turning point is approaching.
This guy is a noob at long range, so he left his cell phone in his shirt pocket, and at 30:30 he gets hit badly by incoming calls from his wife, and he does not realize until he lands that the problem was all the missed calls from his wife.
Again, with 4.25 turns helix+ pinwheel you get 40-50km of range, and with a 8 turn 1.2 you get 50-70km range.

best rx is lawmate rx for 1.2 and best tx is 800 mw sunsky.

[KondorFPV]

staying with boscam 200mw here is another video from the same guy as before going 11km and you can see how hard he gets hit at times.

At least you can watch this at 480p
10800m

Great videos Kondor you've got a lot of long range experience :)

I am currently on 600mw Immersion 5.8 and I am maxing at around 9.5km on a good day and 6.5km on a bad day.

I have a Circular Wireless SPW on the VTX and a Spironet Patch on the VRX. My range seems to vary day to day, and so far in Summer I have struggled to go past around 7km. It seems that atmospheric conditions must make quite a big difference.

I'm surprised as the Spironet is supposed to be a 13dbi so was expecting a bit more when comparing against your results.
