The old antenna 18dB brought unsatisfactory 32% signal. The Philips 40dB antenna brought it ..... 8%! Under no circumstances, this antenna has 40dB gain! The signal was there, just not that interested in the Philips antenna. At this antenna divorced obviously the spirits are either the very good reviews - or very bad. An intermediate, it does not seem to be here. I could not believe the bad reviews and have ordered - unfortunately. Too bad, that must stand on this antenna the name Philips.
