Altron CM35 Compact Antenna Mast
I bought an older Altron Mast from a fellow amateur and it's in great condition and well capable of further use for years to come. Unfortunately I can find very little information on this type of mast online, but I was very lucky that a complete set of erection instructions for various models and specifications, came with my purchase.
I've scanned the paperwork and it's available here as a set of PDFs for anyone who needs such information.
Altron seems to have gone out of production of this model some years back, so it's doubtful any copyright is enforcable and no patents are mentioned. Consequently, for anyone who has the necessary knowledge and the right welding gear and materials, it should be possible to construct your own mast to the same standard and specification.It may also be possible to persuade a local firm of fabricators/welders to build to spec.
