If you want something less permanent, I used 1 (free) 8ft tall telephone pole, buried about 3 ft in the ground, and a 8ft 6x6 post bought at a home improvement store for the two bases. To each of those I ratcheted in two metal U-shaped aluminum strapping, I can post a picture of it. Anyways I found some 12ft poles used for stair railing sold at any improvement store, which is flat on one side. When the hops are going up, I just slide the longer stair railing poles (with eyehooks at the end to guide the cable going across) through the aluminum straps and tighten them up. I take the longer poles out at the end of the year. Doesn't look too bad in the yard and held up well last year. Total height is like 16'. I have 4 mounds and 2 plants per mound.
