Mike: Our install was about $10,500.00 It will depend on the construction of the church. Our loop was installed underneath our floor which had concrete construction but we were then able to loop both the main church and the basement by doing it this way. Some concrete construction has rebar/steel rods which then will not make this possible. Otherwise it can be laid on the floor of the church but typically not above since you will not have a good signal that way. Make sure that the installer is knowledgeable! You can check with HLAA to see if they have anyone in your area that they would recommend. I was right with the installers when they were testing to make sure that my HA's worked well with it. It really has been a good addition! Hope this helps.
