I live in a rural area, more than 100 km from the transmitter TNT Troyes (channel 32), that's how I dreaded test the Elgato key, even dual-tuner. Well after much guidance settings, I get to perfection 19 channels, including HD programs. The recipe: 2 horizontal axes of the antennas towards Troyes, the slightest interposition wall decreases the number of captured channels. Whereby image / sound quality is perfect, and when we tried HD, it becomes difficult to do without. Elgato - EyeTV Diversity - Dual USB tuner - Mac / Windows
After more than 2 1/2 years of use TNT, I return to this review to say that with the supplied antennas, the key continues to operate perfectly.
