How much room do I need?

Since units vary in size, please check the size listed for the jumper you want and then add 4 feet to its width and 7 feet to its length. If you can imagine 2 parked cars in your set-up location, chances are you have enough room. Most 2 car driveways can accommodate up to a 15' x 15' unit. If you have a very long driveway, possibly some of the larger units will fit too. Don't forget your vertical clearance! You'll need an area free of trees, low wires, etc. of about 18-20 feet high.
