Tunipolesâ„¢ are ideal for both directional and non-directional antenna systems. It provides extra bandwidth and efficiency; improves impedance match to reduce tuning unit loss and complexity; has identical radiation pattern to series fed; reduces tower height and ground system requirements; and allows mounting of FM, TV or communications antennas without isocouplers or stubs. No base insulator or lightning transformers are needed. Direct tower ground diverts lightning strikes to protect RF equipment. Combipolesâ„¢ permit up to 3 AM frequencies on one tower.
