    Cable Ends:

    Best option is to go to a professional rigging shop and get this done for you - it's not easy to DIY. The cable needs to be extremely tight around the thimble and the ferrules MUST be crimped using the right tool - not with a hammer!

    Top Pole Cable Connection: There are three poles joined together by threaded connections and the top 1/2" pole has steel lugs welded onto it to accept the cable end as shown.

    Wind Vane Mount


    The wind vane is lower down the pole on a piece of steel angle. Keeping it low down makes it easier to point to north during setting up and prevents it obstructing the anemometer at the top.

    There's a special technique for getting the wind vane aligned to north which involves pointing a compass towards it from about 10 metres away on the ground. The instrument used here has a large black square printed on it which allows us to 'sight' it. It's really handy if the wind vane can be accessed via a step ladder as the adjustment itself is done in a series of stages by repeatedly adjusting on the step ladder and then checking from the ground. Some binoculars mounted on a tripod would have been really useful!

    GPRS Antenna: The antenna used here is magnetic and attaches to a small piece of steel plate with munsen rings to attach to the 1/2" pipe. The antenna MUST point in the right direction!

    Anemometer: The anemometer is bolted onto a piece of stainless tube welded onto the 1/2" pipe right at the very top.

    Pole Ready for Assembly:

    Here's the complete pole rig, except for the 1" stainless tube already concreted in the ground.
