B&Q Beam

I’ve committed to ‘presenting’ the B&Q beam to the club in a couple of weeks so I better get on making it. The idea is one that has been done a few hundred if not thousand times over. Give some new / inexperienced hams the opportunity to build a perfectly adequate 3 element beam for 2m from parts found at a local hardware shop. In the UK B&Q is just about everywhere and it supplies just about everything, apart from the thing you want, generally.

Seriously the design is taken from any of your favourite calculators. I have found that they vary slightly against the original maths but I know my Sotabeam works very well so that’s a good starting point for dimensions.

Costs to date are in the region of a few quid but by far the most expensive parts are the nylon bolts used to hold the elements. I’ve bought a bunch so I’ll have a few attempts at drilling straight through the nylon without heating it up too much.
