I bought this DVB-T antenna for my parents and I must say: TIP. They have anyway not the best reception via DVB-T (an average of only 4 to 6 of 26 possible channels). With this antenna, we always receive back 18 programs, of which 12 are good in absolute top quality and the other 6 also. Only in bad weather conditions the receipt of these 6 stations is disturbed (blocks formation). The Schnönste is that you need no extra power cord. The installation is easy: plug in antenna and you're done. Note: When DVB-T receiver enable the active reception - if available, otherwise the gain does not work! One could possibly think otherwise that the antenna does not work, but do not panic it works!
