J L Eve C15 0.1″ SCA

Contents

Overview

J L Eve C15 0.1″ SCA is one of two sets of towers designed for the joint NEE SL1–MEE SL2 (North-East England and Mid-East England) contract. Alongside the 0.1″ SCA type, Eve also designed a 0.15″ SCA type.

The drawings all have corresponding C15 and C23 numbers. Possibly one range was for NEE and the other for MEE; the C23 numbers were added afterwards as all drawing cross-references use only C15.

Tower details

Base widths are, uncharacteristically, between the centres of the stubs at ground level.

Some details are approximate or best guesses only due to poor reproduction quality of the original drawings.
