Description

The folded dipole assembly is mounted to a cast aluminium hub. The centre feed is taken out through the hub and a RG213 coax tail is fed down the centre of the boom and terminated with an N plug connector. The antenna is DC grounded. Mounting of the boom to a vertical 48 mm OD tube can be achieved with a Cross Clamp (CLCR). This allows the dipoles to be spaced from the mounting tube to provide an omnidirectional or offset radiation pattern. The offset pattern provides a further 3 dB gain in the offset direction. This is shown in the radiation pattern on page 18 with “A” being the 1/4 wave offset and “B” the omnidirectional radiation pattern.
Downtilt can be provided by inserting delay lines in the feed system.
