No. 21-869 10M Ham/CB Base Antenna Your RadioShack 10M Ham/CB Base Antenna provides excellent reception of amateur radio, CB, and commercial radio signals. The antenna can handle up to 2000 watts of transmit power. Your antenna's features include: Electrical Half-Wave Design -- provides high gain. Note: To improve your antenna's gain, you can connect an optional ground plane kit (available through your local RadioShack store) to your antenna. Three Easy-to-Assemble Sections -- help you quickly and easily assemble the antenna. Dual Tuning Rings -- help you quickly set the antenna for optimum performance over a wide range of frequencies. Ultraviolet Inhibitor -- the antenna's UV-protected housing is made of impactresistant fiberglass, making the exterior resistant to weathering and color change. Strong Internal Construction -- prevents the antenna's internal wires from rattling, for maximum strength. IMPORTANT SAFETY PRECAUTIONS Many do-it-yourself and professional antenna installers are injured or killed each year by electric shock. Many power wires are within 20 to 25 feet of the ground and could easily be touched by an assembled antenna or cable. Touching the overhead wires with any part of the antenna is the same as touching the wires with your bare hand. Contacting an electrical wire almost always results in a very serious shock. To avoid electric shock, please read and follow these important safety precautions: · Be sure to select an antenna site well away from all overhead wires. · Do not try to guess which overhead wires carry high voltage. Check with the power company. · If you notice anything making contact with the overhead wires, call the power company to have it removed. · Do not run the antenna's cable over power wires. · Get help from a qualified professional when removing the old antenna, especially if you have any doubt about clearing overhead wires. · Never install an antenna by yourself. Be sure to have at least two people available for help. · Never install an antenna on a windy day. © 1999 Tandy Corporation. All Rights Reserved.

Always use 50-ohm coaxial cable, such as RG-58 or RG-8, to connect the antenna to your radio. For lengths over 50 feet, use RG-8 low-loss dielectric coaxial cable. Your local RadioShack store carries a wide variety of coaxial antenna cable and connectors. Warning: When you install an outdoor antenna, use extreme caution. If the antenna starts to fall, let it go! It could contact overhead power lines. If
