Which frequency does the original NBiOT antenna work on?
The reason I am asking is because I want to test few other antennas.
Also found that Sodaq is now supplying a new “pcb” antenna, but there is no specifications on the info of it.
LTE has many frequency bands, see https://en.wikipedia.org/wiki/LTE_frequency_bands . It depends on your country and your MNO which band is actually used. E.g. T-mobile in the Netherlands uses band 8.
I see we don’t provide information in our webshop.
They both work on band 5, 8 and 20. The new pcb should support more bands.
I made a note that we update the shop with some more information soon.
If you want the best performance you should buy an antenna tuned for the band your operator is using.
