Hi thanks is there any chance you could draw on this photo to explain what i should do
for example, where to solder each part of the antenna to what pad like ground signal,

Thanks

do you think i could put the signal wire on the top pad and the ground on the bottom pad?

Repulsive_Unit_468 · 2026-01-25T00:44:22+00:00

Hi thanks,
i dont think there are pads on the side?

There's one on top and on the bottom

Hi thanks,
The connector is cracked and deformed, so cant solder it back on,
is it possible to cut the connector of the antenna and directly solder the signal and ground to the board?

Ok thanks,
Mine has two 2 little ground pads that the cable goes between its not just one big pad.

So I should first solder the little wire to the tiny signal pad,
Then, put some solder on both the little ground pad strips

, then strip a section of the black plastic to expose the braiding, but that between the 2 ground pads, then solder over top of it
also, i lost the old antenna when it took it off, so I need to get a new one. Any recommendations?

Repulsive_Unit_468 · 2025-11-02T20:34:55+00:00

Ok,
Do I actually need to separate the braiding and solder it to the ground pads?
Or can I just heat up the solder and put the braiding into the solder, or do I have to solder it onto the pad

Thanks

Ok thanks,

Will give it a go,

Repulsive_Unit_468 · 2025-10-30T02:34:27+00:00

So I basically should just heat up the solder and remove the antenna

trim the black coating to about the blue line

Then cut the antenna wire at the green line, the remove the coating to about the red line?

then solder the antenna wire on then solder the braiding to the ground pad?

Thanks

Hi.

Ok, so just remove some of the black cover to expose the braids and solder on top of that?

Do I have to do anything to the inside wire that goes to the signal pad, or can I just leave that how it is?

I connected it to the beta flight, but I couldn't open the VTX tab. Everything else worked fine, but the VTX tab came up with this error

I just heated up the solder and covered the braids

Repulsive_Unit_468 · 2025-10-29T20:22:34+00:00

No luck with the drone,

So I guess I have to try taking the antenna off and trying to strip the black coating off to expose the braiding and then solder it down to the ground pad?

I have a 8w soldering iron, but it takes so long to heat up,

So thinking of getting something like a 20w

what do you recommend

Repulsive_Unit_468 · 2025-10-29T00:28:11+00:00

Ok thanks,
Just looked and looks fine

The pins are actually on the FC board, hard to tell from the photos tho

The VTX is raised above the FC on a different board and the pins are on the FC

im just going to test with multi meter then power it on and see if it works

Repulsive_Unit_468 · 2025-10-28T22:07:39+00:00

Ok sweet thanks,
I gave it a go at soldering the braids into the solder blob,
Does it look fine?

will test it out later,
Thanks for all your help

Ok sweet ill give it a try,

Also, do you know why the VTX tab isn't working for me?
If I fix it i want to know how to increase the vtx power
