Description

Construction is from heavy extruded aluminium tube with a rugged cast aluminium centre clamp. This clamp is then attached to the boom with three radial bolts to provide a reliable connection. All hardware is stainless steel. To increase the corrosion resistance, the aluminium element and boom are silver anodised.
Each Dipole is fitted with a RG213 coax tail, fed down the boom centre and terminated with an N plug connector.
By adjusting the spacing from the steel supporting mast or reflective supporting structure, an offset radiation pattern is achieved providing more gain in the favoured direction. This is shown in the radiation pattern on page 23 with “A” being the 1/4 wave offset and “B” the omnidirectional pattern. Down-tilt can also be provided.
Items supplied for the FMD3-SA – 2 x Dipoles (FMD), 1 x Power Divider (PD-2L)
Items supplied for the FMD6-SA – 4 x Dipoles (FMD), 1 x Power Divider (PD-4L)
