The Hawking Technology Heavy Duty Outdoor Extension Cable is made with the highest quality material to provide unrivaled reliability and performance. Antenna cables are subject to signal degradation due to the length of the cable. The longer the cable is the greater the signal loss. This results in a loss in overall performance from the antenna. Hawking Technology ensures the lowest possible cable signal loss by using high grade cable material and advanced designs. The HAC10N and HAC30N both utilize, HDF400 cable material which results in a 0.26 dB per meter cable loss (one of the lowest in the industry). Your final result is the desired and expected performance from your antenna. The HAC10N and HAC30N are completely weatherproof and able to withstand the harshest conditions. The HAC10N is fully compatible with Hawking"s entire line of Hi-Gain Outdoor Antennas and any N-Type antennas Hawking Hi-Gain Outdoor Antennas: HAO9SIP - Outdoor 9dBi Omni-Directional Antenna Kit HAO9SDP - Outdoor 9dBi Directional Antenna Kit HAO14SDP - Outdoor 14dBi Directional Antenna Kit
