FPV video goes out after few meters?

Hello... OK I admit I bought low budget FPV kit from eBay (rx RC5808/tx TS58200).
But anyway is it normal to have video noise on few meter distance???
Look video:
myfpv (0 min 8 sec)


But when I go out on open area the video is gone after 10 meters?? Black! Nothing..

I try different anntenas, changing channels,... ok channels chart is little confusing.

Remote is 2.4 GHz and FPV is 5.8 GHz.

Any idea?

Thanks,
Erik

Might be that Channels between VTx and VRx don't match.
Is a frequent error.

Yup. Time for a range test with two folks on cell phones. After the one with the TX gets out at a appreciable distance cycle through the base station setting until you get the best reception. You're done.

Just to clarify what the guys said above- the channel numbers labeled on the transmitter do not match the channel numbers on the receiver. TX ch 3 might be RX ch 8. It's a crap shoot. Only way to tell for sure is to cycle through until you find one that works well.

one of two things.

One of your antennas has a broken connection somewhere,

or your transmitter is putting out very low power
some times a transmitter comes new like that, and sometimes it can happen from something like overheating, or running without an antenna.

How about SMA / RP-SMA conflict?

The key is to have a male/female connection internally with the antenna adapters

I also just got that combo. First off, follow the transmitter manual for dipswitch settings(the switch position is in black). For the receiver, don't follow the manual but the sticker on the back. This time, however, the switch position is the opposite of what it shows(you can think of it as the white space as the switch position).

I'm testing this in a car with my 9x and found that the fpv receiver being too close the radio antenna could cause some interference. Even after repositioning antennas I'm still only getting about 30m which is pretty disappointing since I hear you should get at least 200-300m.

I'll try to scan all channels. I will set CH1 on TX, and then I'll test all CH on RX :/
The antennas are OK.. and conntectors too.
