One of the best antennas for repeating Wi-fi antenna FA20 17-22db (FA-20) But it still works fine for 2500-2700 dimensions recalculated using the coefficient of 0.935
alex07111971, I'm in the radio technology, I do not rummage at all. Maybe someone can tell me the answer to one of my questions?
1. Found one scheme
antennas for 3G modems, the antenna operates in the 1.93-2.18 GHz range (
here is the link to the source ), but to make it work as well as
and for 3G the gain is 15.6-15.8db ,
for Yota, its size needs to be recalculated . Do I get it right?
And the recalculation is done according to the formula of
of this article, it is only necessary to count with its parameters, namely:
2. If the antenna for
3G works in the ranges: 1.93-2.18 GHz - the average value = 2,100 GHz And need
antenna for Yota, average range = 2,600 GHz , the formula for calculating the coefficient will be as follows:
2,104/2,600=0,809 ?!
Correctly though I reason? 3. Well, now you will need
All dimensions from 3G antenna circuits multiplied by a factor of 0.809. This is the size of the antenna for Yota.
Guys, who understand, tell me pliz, I understood everything correctly?
THANK!
Oh, and one more question!
If I assemble the antenna, how to connect it to Yota Many, here is the link to
this device, can through an external cable, and how to attach it to a modem?
I heard that he may have an outlet for an external antenna under the case.
Who knows if this is true?
THANK.
