The antenna is compact, small and eats no extra power. You shall possess a strong magnet for mounting eg on a wall or similar thus it is also very stable on a shelf and not slip through the "hanging" cable again from the spot. I have since then, regardless of the weather or whether just calling with mobile phone and Wi-Fi, etc., had no more interference. This antenna is simply superb! Thank you for this great product - I can this antenna Recommend unreservedly.
