Fig. 13

This figure shows a tracker and tag boat (upper left panel) with the DFHorten rigged in a weatherproof box ahead of the front glass and with 4 5-element Yagi antennas. In this setup the weather box can be regulated, so that the upper bridge and the cabin can read the DFHorten output. In right panel the antenna rig is at the top of a sailing boat mast, including both antenna frequencies for the DTAGv2 (148 MHz) and the DTAGv3 (219 MHz). In lower left panel the antenna rig is at the bow of a larger vessel. Photo by Lars Kleivane
