I woluld like to buy this kit from B%H

http://www.bhphotovideo.com/c/product/324228-REG/Sennheiser_EW100ENGG2_B_Evolution_G2_100_Series.html




I can see there are two different frequency range

A 518-554 MHz

and B 626-662 MHz

Considering that i will use this mic in different countries(USA,Argentina,Spain ,Italy,Cuba...etc. etc.) which one of the two is the best for me?

Or maybe they are both useless to me and i have to look for something else?


thank you

Here are frequency finder tools from Sennheiser.

For countries not on the chart, find out what TV channels are used in country/city and compare to the U.S. chart that lists all the frequencies, channels and matches to the Sennheiser Evolution G2 frequency ranges.

I am guessing that for remote areas or areas with few TV broadcasting stations, any of the ranges would be okay, so the choice should be made on European or U.S. frequency needs.
