We decided to test the new “Royaltie Gem” on a football field. We actually went well over the 100 Yard marker because the goal posts are 10 yards in from either direction. We received it at 120 Yards in a crystal clear path of just a football field. Steel, and brick do dissipate the signal, but not kill it, its just the more walls you go through the lower the signal may be depending on what it was constructed with. Steel and Brick aren’t friendly and strongly disapate the signal, so I don’t ever expect it to go more than 1 room into a building, unless you have glass, glass is good as it broadcasts right through it!
