My Cushcraft X7 Big Thunder yagi antenna worked great for about 15 years. Eventually the ends of the reflector bent down; last summer I encountered high SWR and now couldn't tune it up. I bought a Raising fixture from US Tower to make work easier. I suspected the coax cable for open or short, but when I lowered the tower and removed the antenna I had a big surprise; the power leads to the antenna from the network box (balun) were missing! For years, the braided wires were vibrating in the wind and finally broke off. I took down the rotator too for maintenance. It's a Create RC5-1, in service since 1990!
The raising fixture worked great after US Tower sent me the idler pulley free of charge. I have an old tower with no place to attach the pulley, so they manufactured an attachment for me, thank you very much!
Just three weeks passed since I took the antenna down and I got all the parts I needed. I repaired the yagi elements by replacing the bent tubes and inserted 12" aluminum rods and tubes to the joints so it's not likely that the birds can bend them again. I also painted the antenna and the tower and replaced the steel rope that holds the inner section of the tower.
I found out on the web that the manufacturer of the Create rortator in Japan still makes and sells the rotator I have. I needed a plastic gear and the seal ring for it. To my great surprise they immediately sent me those parts free of charge! Thank you very mch!
It took four weeks to finish the job; I am back on the air! My first DX contact was J49C from Crete, Greece.
