I ordered the antenna, since I live in the outskirts of a DVB-T and have promised me a stronger reception. I use an Elgato DTT Go USB flash drive for the Mac. When I connect the supplied thin cable wire antenna of the USB stick and directly compared against the CSL-rod antenna with "copper core" exchange, it must be noted, the thin wire delivers more stations and also with more field strength. Same location, same distance to the Mac, all the same ...
I then connected the antenna once made fun of my Tivoli FM radio. Again, there is no difference in the reception for wire antenna to sense and certainly not to the built-in device radio antenna.
So all in all a waste of money. Only for the long cable and a possibly better positionability there are 2 stars. If it should, however, give an extension cord for the Elgato wire antenna, I would prefer this in any case the "Copper Core" antenna.
