SNW 10 was a maritime early warning radar operating in the VHF-Band It was installed on Spanish frigates in the early 1950s, some of which were later sold to Chile.
The antenna consisted of two rows of three horizontally polarized dipoles, each in front of a commonly used reflector. These dipoles were relatively thick for better bandwidth. The extension to SNW 12 with a higher number of dipoles (see Fig. 1) may not have been realized in practice.
