Vertically Polarised FM Dipole

The ADB-FM1 Vertically Polarised FM Dipole Antenna is a simple solution. The design supports low power FM radio stations requiring up to 1 kW input. The FM-1 antenna will support 2, 4, 6, or 8 antenna tiers or bays. These will provide a gain of 5, 8, 9.8 or 11 dB respectively. Please also see the downloadable datasheet to understand the coverage lobe prediction.

Vertically Polarised FM Dipole

The suggested diameter of the mounting pole is between 60 and 110mm for security. Furthermore, FM-1 dipoles mounted close to large towers or close to large metal masses might find the radiation lobes altered. Additionally, the VSWR reading can be affected. Also, the suggested distance between the dipoles for a broadband system should be 2.6m.
