The Hawking Technology HAC30N Heavy Duty Outdoor Wireless Antenna Cable is made with the highest quality material to provide unrivaled reliability and performance. Outdoor Wireless Antenna Cables are subject to signal degradation due to the length of the cable. The longer the Outdoor Wireless Antenna 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, HAC20N and HAC30N all utilize RG-213/U cable material which results in lower signal (db) loss/meter. Your final result is the desired and expected performance from your antenna. The HAC10N, HAC20N and HAC30N are completely weatherproof and able to withstand the harshest conditions.
