The HI-Q Balun is designed to handle full legal power with a low SWR (standing Wave Ratio). The most important factor contributing to a low SWR is correct antenna length. Most effective operation is acheived when the antenna is in the clear, away from guy wires, power and telephone lines, trees, buildings, etc...
Do not disassemble the HI-Q Balun. Once any of the eyehooks are disassembled, the balun can not be reassembled.
