TIU Placement

We have 2 of them mounted under the layout (26' x 17') and don't have any issues. Pull the rubber feet off the bottom, enlarge the holes just a bit and use some #4 x 1/2" or 3/4" screws to mount it where ever you want. Just don't tighten it so tight that you crack the corners.

Functional and out of sight.  My TIUs hang from solid #12 wire for easy removal for upgrades.

I assume there is no connectivity issues with the TIUs under the table.

As long as no metal comes between the TIU and the remote you are fine.

Mounting under the layout can put track between them if you are reaching out over the layout with the remote.

I have to reach around a water heater that sits in the middle of my layout area. It's a real signal killer. MY next layout will see the TIU mounted above that water heater. I can hide it in a forest on the mountain that will hide the water heater.

We had our TIU at track level in the club layout, and we had remote communications issues.  I put it on a shelf about 4 feet above the layout, level, problem solved. 

The higher the better, especially if there are obstructions.

Thanks for the input. I see that there are several ways to go.  I don't know how I would manage placing the TIU above the layout asthis would make wiring runs much longer but if I have weak signal I will have to re think.

Totally confused.

I thought the TIU was raised to promote communication between the TIU and handheld because it is a air signal. The TIU talks to the trains via the wires and track so height of the TIU would not matter.

I have 2 layouts with the TIUs buried under the layout and no remote communication problems.

At or above track level.

I am going to move mine up, but then were do I get the long AIU cables? I sure don't want them hanging from the ceiling.

Correct, at least that's the issue we had.  Raising the TIU allowed the remotes to connect all over, when it was below the track height, we had issues at the far end of the room.

The AIU can be located anywhere.  The cable wire is available everywhere.  We have had luck with the length of the AIU cable being about 40 foot long. 

     Ihave my TIU mounted like this with no problems.
