Hmmm, 200 ft and a metal building.

Personally I would have the incoming service installed where you'll be comfortable accessing most frequently...perhaps your home office. If using one PC in the home then use the router that usually comes with the service or purchase one (no need for wireless) for a few bucks.

Then I'd run a Cat 5 or 6 cable from the home router to the Pole building and either terminate to where your laptop plugs in or to a wireless router. The wireless router (aka access point) will allow you to place the laptop any where in the shop.

Remember that the best throughput is going to be realized through a hard wire installation.
