Judge for yourself if 'scam' is the correct term to use re. the Lava antenna... I won't contradict you if you choose to use the term. Only in the most extreme theoretical scenario could you defend such a physics defying claim as '150 mile' range. Discounting the active amplification (which doesn't add to the real gain of the antenna) one might hope for 3 to 6 dB of forward gain based on the size and shape of the antenna. There are plenty of reviews that consistently report problems with the quality and durability of the materials used. Plenty of other reviews appear to confirm the doubts re. the performance claims.
Please review these instructions on how to provide sufficient information re. your signal conditions,
