I have a steel building in the mountains. On a GOOD day I have 1 1/2 bars of signal. I bought a Z boost which brought the signal INTO my steel building, again 1 1/2 bars. I contacted WILSON Electronics who had built the Z Boost. They said that the "indoor mounted antenna" would greatly improve the signal. I installed it, no help, I added up to 25" of coax to get it farther from the Booster (at their direction)...no help. I moved it all over the building....no help. I get the same reception with the "L" antenna.... Waste of money.
