Where to solder the contacts for the wi-fi whistle to connect the antenna?

Question

WiFi

I don’t understand this topic, but I know how to solder a little and I know some basics.
I am making an antenna according to this manual: www.qrz.ru/schemes/contribute/antenns/wifi/bi-quad
...
1. To connect the antenna, I use a HiFlex rg-6 high quality plus coaxial cable.
2. Wi-fi whistle model NICW-U3. I am enclosing a photo of the board from both sides:
photo a hkar.ru/qWAL
photo b hkar.ru/qWAK
Questions:
1. In photo "a" you can see a track that plays the role of an antenna, as I understand it. I cleaned it up and soldered the wires. Should I connect the inner conductor of the coaxial cable to this pin?
2. On the photo "b" you can also see a track resembling an antenna. I don't understand if this track has contact with the track on the other side or not?
3. Do I need to cut the contact to these tracks so that the signal from this internal antenna does not interfere with the signal from the external antenna?
4. Where to connect the outer conductor (shield) of the coaxial cable? To the ground? Will the usb connector connect to ground? (marked with circles in photo "b")
Thank you in advance for your help)

Answer 1

Well, for starters - rg6 is not suitable, this time It's
worth taking www.ebay.com/itm/New-Pair-Notebook-2-4GHz-5-2GHz-R...
and using the cable from these antennas. Or rip out the cable from the dead laptops. Such a cable lies from the wifi card to the antennas in the cover of laptops.
Where the yellow cable is soldered in the photo - it's too late to catch something, you are soldered at the end of the antenna.
In the same photo, there is a six-legged switch, and a path that goes to the antenna and a black smd resistor. Remove the resistor, and solder the central core of the coax to the track that goes to the six-legged switch. solder the braid to the ground in the same place nearby.
Do not forget that you are dealing with a microwave. So the cable length is no more than 1 meter, the central core without braid is no more than 1-2mm! And the minimum length in millimeters separately of the braid and the central core. Soldering the central core to the switch, and the braid to the USB connector is unacceptable

Answer 2

I made one myself a couple of years ago for a router))
