The J-Pole makes a great base station and emcomm emergency communications amateur radio and scanner antenna. Works well with handheld HT radios, base stations, and repeaters. Ruggedly constructed one piece design, this J-Pole antenna will last practically forever. Copper has an extremely low electrical resistance, making it one of the most efficient materials for RF radiation. I have worked repeaters within 20-40 miles of my house with this it works well.
