greater Wi-Fi area for ESP8266-01 with external antenna

---

Hello
I had problems with the Wi-Fi for some time reach of an ESP8266-01.
Therefore, I have searched for a solution and found this antenna:

You get two antennas and two cables for the money.

Then I broke the trace of the original antenna in these two places.

Then soldered to the head of the new antenna to the rest of the trace and solder the shield to the old antenna.

Now I have a much better Wi-Fi coverage and a better grid stability as before.

Possibly, the shielding of the new antenna with GND should be connected. But it works for me so great.

A soldering station and a good magnification is an advantage for this work.

very nice, thx for sharing!!

as i understand correctly, you solder the shielding wire from the new antenna to the cut off antenna on the esp just for stability purpose only.

Yes right. I have used the SHIELD only to the pull relief.

I have used it before to GND. But I saw no difference.

Every Antenna needs a ground. If you are just using a wire as Antenna, your Board is the Ground (or if you a near the Board, like in your case) With a meter cable between, this will not work!
