At the beginning of 2008 I received planning permission for a new 13M high mast. This will support  a Hexbeam and a 6M Yagi.

To install a new mast you first need hole!

Mine is 100ft or 30M away from my house.

Install the shuttering around the hole, don't forget the quadrant around the edge.

I'm thinking ahead here and as well as the socket for the slim-line mast I'm going to install four x M24 foundation bolts, just in case I need to change the mast at a later date. The nails mark the centres for the M25 holes, here the foundation bolts will dangle down into the concrete.

Here is the 100mm wide post and it's socket. There were made by Henry Cooch ltd.

Here the socket is resting on a galvanised steel support and the post is resting on some cross-timbers. This way I could be sure that the post and the socket were vertical.

A closeup of the supporting frame, note the plastic cable ducting, these short pieces were retrieved from a skip.

A hole of 2 cubic metres requires 4 tonnes of concrete. This was mixed at a ratio of 1-1/2 cement, 2 sharp sand and 4 ballast. This took 3 people about 5-1/2 hours.

The finished result, now to tidy up the garden and install the mast and the aerials.
