I've a LTE router with WiFi, it switches automatically between LTE bands 3, 5 and 40, depending on the respective signal quality.
I want to improve the band 40 reception. So I think the easiest option is to remove the band 3 and 5 antennas. As the propitiatory firmware provides no interface to switch or lock a specific band.
The main problem is identifying the correct antennas to remove. The device has 4 patch antennas, printed on yellow mylar films. All of them looks similar to me!
So how can I identify the band 3/5 antennas ?
The WiFi chip is WIFI-107E :http://www.kynix.com/Parts/3253319/WIFI-107E.html,Device is made by Pegasus Telecom, subsidiary of Haier.

Discuss commercial and home made antennas.
