Signal of the antenna is good when it is properly aligned, the main pillar is made of plastic like everything else. If the foot is attached it slips out quickly when the antenna is moved. The power cable is very thick and heavier than the antenna, you should put the cable so that you do not topple the antenna :-( Totaly makes the Strong SRT Ant 30 Eco Qallitativ a bad impression because very light and fragile. Have the antenna sent back.
