| + | Multi-band vertical, using an ATU. This will need a substantial ground plane to achieve efficiency, however should provide a low radiation angle suitable for DX. If longer than 5m it should cover 20/15/10m. It may be possible to increase the length by hanging a wire from a tree or combining some aluminum tube with a pool-pole. Alternatively, a 9m fibreglass squid pole may also make a suitable support. | ||
