What kind of amplifier is this ?

If is used BFG65 as main transistor then maybe worth something ..

but if are used anything else then ,,,is so so

 Heart of the antenna is low noise digital amplifier, high-frequency chip Kzt67. Philips c gain 22 dB.

I greet you admin !!!! I want to talk about the antenna Cifra-9. You can try to do, but we need the exact dimensions!? I saw video numbers 9 but without an amplifier, an interesting thing!

[Admin 2421]

Hello my friend, I do not have the dimensions of these antennas, but I will try to simulate something similar..!!!

You have the dimensions at this antenna...??

"option diversity" in /etc/config/networks - works only with Atheros chip ...

---
I found solution - "antsel.c" can control output antenna
Maybe someone have a build for openwrt?

.,,,"antsel.c" is the source code of linux/drivers/net/wireless/broadcom/brcm80211...???

,,, user "com666", has developed a variant of this antenna (orthogonal) in a personal way by adding a directory...

,,, and these are the results of the simulation .... !!!
