Flysky FS-i6 is damaged and questions about the antenas of the reciver

#1
I bought a flysky fsi6 transmitter a while ago but a few day ago the buzzer started to get quieter and quieter until it simply complitly muted. I tried to replace it with a new one but the same happen after some time passed... Does anyone know what could be the problem.
And the question to the antenna:
I'm new to this hobby and been wondering what dbi stands for? I also chopped the antennas from my fsia6b of and already bought new ones but I realized that the new ones doesn't have those thick metal thing at the end... Is this a problem? And what is it for, because I thought ground and the inner metal surrounding are already shielding it?

what dbi stands for?
dBi stands for decibel isotropic, it is a measure of directional power.

It could be a problem.
The "metal thing at the end" changes the antenna form a mono-pole to a di-pole antenna. A di-pole antenna will have more range than a mono-pole antenna. As long as you are flying line of sight, the mono-pole antenna should work. If you try going beyond los it could be an issue. After a crash or repair a range check is always a good idea. In this case, I would highly recommend a range check.

Here is the 1st of 8 great videos, if you want more. Great introduction on how antennas work, well worth the time.

Do you have a link for those special antennas, do you know a better one and what's the name of those special antennas so I can look around by myself?

Is this the right one?

I think the one you linked to will work. I'm not sure about the IPEX end, I don't know if your Rx has the same end or not. My older Flysky receivers don't use the IPEX end. On mine the antenna is soldered on to the board.

These looked like a better value https://www.banggood.com/10X-3DBI-B...=detail-left-hotproducts__14&cur_warehouse=CN
OK... I use a flysky fsia6b so... No it doesn't have a IPX connector but I already changed the antennas quiet often so I know how to solder them but your link is way better... I'll use that one for sure
