BM10T Mast - change to luffing system
I recently installed a second-hand Radio Structures BM10T lattice mast for my 2m EME array. The BM10T is similar to a Versatower but has a simpler luffing arrangement with the wire attached to the bottom of the lattice section and running through two pulleys either side of the base post and up to the winch. The pulleys simply act as guides for the wire and provide no mechanical advantage. This makes luffing hard work with the antennas installed.
