Where do you mount the TST 507 series Repeater?

Mine is mounted to the back window in my truck with double sided adhesive. But I have a 12 v outlet in the storage area under the back seat. I added an in-line switch so that I can easily turn it on or off depending on towing.

We didn't need it until we bought the longbed crewcab. Then it would randomly loose connection. We bought the repeater at Quartzite. Installed it on the rear wall of the front cargo area. The area under the hitch. Haven't lost connection since.

I have a 42Ft 5th wheel and Do Not need a repeater. I also have the 507

I've heard of some being put in the closet in the bedroom. Others have put them in the basement. Might just have to try different places. I'm hoping when my 5er comes next spring that I won't need one.
