Using this product is a breeze. First, find the 500 series VHF or AIS antenna you want to extend. Take the DA624 mini-UHF double male adapter and connect one end to the antenna's mini-UHF female connector. Then, connect the other end of the adapter to the mini-UHF female connector on the 20' cable. The other end of the cable can accept the 500 series antenna’s PL-259 adapter. When using, avoid bending the cable too sharply as it may affect the signal. Also, keep the cable away from high - heat sources. For maintenance, clean the connectors regularly with a dry cloth to prevent dust and debris from building up. If the cable is exposed to water, dry it thoroughly before reuse.
