LBA Tunipole™ Folded Unipole Antenna Systems deliver higher efficiency and bandwidth than series fed towers while providing lightning protection. Tunipoles™ 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. Combipoles™ permit up to 3 AM frequencies on one tower.

The LBA Technology Q-Cage™ is a cost effective way to increase power handling capacity and improve impedance characteristics of series-fed vertical radiators. Through use of Q-Cage™ systems, the bandwidth of existing short antenna towers can be improved without tower replacement. This permits the use of shorter towers for IBOC and DRM digital transmission. Applied to high power medium wave antenna towers, the Q-Cage™ reduces voltage stresses on insulators and antenna tuning units. The LBA Q-Cage™ system may be installed on any structurally suitable guyed, series-fed tower. It features the same low wind load, heavy duty construction found in the popular LBA TuniPole™ folded unipole systems, proven in use by thousands of MW/AM stations worldwide. The installed cost of the Q-Cage™ is far less than that of an equivalent cross-section tower.
