PROBLEM TO BE SOLVED: To provide an easy way of supporting a compound cable 41 which is formed by twisting n pieces of cables such as a duplex cable and the like on an antenna tower 38. SOLUTION: Cable support fittings 40, 40 are fixed on the antenna tower 38 at a pitch D. The compound cable 41 is held inside a supporting hole provided in each cable support fitting 40, 40 through a bushing made of a flexible material. When P is taken as the pitch of twisting of the compound cable 41 and k as a natural number, D=k.P/n is satisfied. As the result, the middle part of the compound cable 41 is surely held by the cable support fittings 40, 40 by matching the orientation of the inner peripheral shape of the bushing with that of the outer peripheral shape of the compound cable 41. |
