The Cushcraft A4S is a four element triband beam. It has a 50 Ohm feed and utilizes a twin terminal connector, so no balun is required. A pinned boom section, and formed aluminum brackets keeps the antenna straight, even in high wind situations. Using all stainless steel hardware, fiberglass insulators, and waterproof traps, the A4S will provide years of trouble free operation. The A744 is a 40m dipole add-on kit.
