Report Betso Bowtie in Equipment Posted February 20, 2021 I own an old version Sixpack whose RF-design is far from perfect. The internal connections to the antenna jack's are just unshielded pcb traces which therefore act as antennas themselves. Also the BPF filtering happens after the signal amplification. Nearby TV or LTE transmitters will easily overload the amplifier before they can be filtered out by the BPF. I don't know if they fixed these design flaws in the new version Sixpack or the 4 or 12 pack. I would be very interested in pictures of these products with the top lid removed.
