    No, this is a TM66 model. The A1A is a different monitor station. We have the 'A1A with 6 sensors kit' listed as SKU#109180 and the 'A1A with 4 sensors kit' as SKU#109181.

    Where the signal booster is installed depends on what application it is being used for (truck & trailer, motorhome, motorhome & toad, etc.), personal preference, overall length, and accessibility to constant power that is not part of vehicle ignition. It is highly recommended that you refer to the manufacturer's help page here that provides more detailed information for signal booster installation and examples of where to place it.
