More Than One Transformer per Antenna?

I'm in the process of installing a TV Antenna in our attic. In the next few months, we'll be blowing in ~18" of insulation so we won't have much access to the attic after that. I'm thinking about installing two transformers and running two coax lines to the antenna. Only one coax line will be in use at a time, so I want to use the other coax as a back up in case one transformer bites the dust. Can I even do this (or would having two transformers effect the impedance)? Also, how reliable are these transformers--maybe I'm just adding extra work/cost? I searched for this online and I can't find a single person that mentioned this question.

For clarification, here's the transformer I'm referencing:
