Wingard amplified antenna

When there is no electric available (dry camping) Will the amplified antenna work off the battery or does it require 120 power. If it will work off battery, how big is the draw (compared to other draws), How much could it be used before draining battery substantially?

The amplified antenna works from the battery, and draws very little power - much less than the TV it is feeding, for example.
