70Mhz Double Turnstile Antenna

Those are plastic supports for G8SEQ's double turnstile antenna for 4m (70 Mhz). It is great performer, but not easy to make without proper supports for the mast. Using 3D printing allows for very precise recreation of the antenna with excellent symmetry. Extra parts needed - few cheap SO-239 sockets, some wire, wood screws, washers and 8mm alu pipes, 1m each from B&Q (if you're in the UK).
