Many thanks Guy-yes indeed and thanks for the PDF nice works well done, bit of an Aerial fan and dare I admit to a soft spot for spotting too. But I find them and the builds plus the sciences etc that go with them fascinating. Its what Radios all about in this area of the Genre

I did a fair bit of experimenting myself in the mid-late '70s - adding extra directors to an Antiference 4-element 'standard' product (not much improvement) - ending up with 2 x Fuba UKA8s stacked vertically with a tuneable masthead pre-amp, all rotatable by means of a 'Stolle' system. I acquired a copy of 'Antenna Engineering Handbook' by Henry Jasik which has a nice mix of practical and theoretical approaches - I've often wondered about having a play with computer-aided design but without access to some form of testing 'range' it's hard to verify the success (or otherwise) of one's efforts ...

I knocked up a wooden gizmo for making folded dipoles - pic to follow

Best wishes

A finished dipole + junction box - the balun was taken from a Maplin 300-75 ohm unit ... subjective testing indicated the latter to be quite lossy compared to that using the 'bifilar rod' type of balun i.e. the Hans Kolbe original.

No, just comparison of signal meter levels / subjective 'before & after' audibility of known but distant stations.
