Before you install a rooftop antenna or satellite dish, be sure it is away from any power lines. It's best to locate antennas and dishes where they won't touch or fall on electrical lines if they happen to be blown off. Also, be sure to properly ground them to avoid any electrical damage to your home and appliances.

When lifting a wall section into position, the bottom of the wall can slip across the floor deck, and even fall off. If you are short on help, a solution is to position the section as it lays flat, then drive duplex nails (with two heads) through the bottom plate into the floor. The nails will bend as you raise the wall to a vertical position. After securing, pull out the duplex nails.
