Tilt-base is not supported directly from us however DX Engineering do a tilt-base and so do Barenco in UK.
The ID of the base of the is exactly 50.8mm / 2-inches. You can build a simple tilt-over base with a stub mast not longer than say 30cm / 1 foot long to support the base.
You can guy this at the 3rd spreader. You DO NOT need a tilt over base.. This can sit directly on the ground. (You can also storm-proof it by guying at plate #2 and plate #4 instead)
Radials: Enough to get you nice and loud on 80m and louder on 40m and up. Pin these down either with radial pins or wood dowels / lawn stakes etc.
Note: We don’t supply those little plastic carabiners for the shock-cord ends any more. They becomne brittle and break. We moved to a superier solution of stopper knots and loops. See User Guide.
