FAQ
Can multiple antennas be combined for higher gain?
Yes, multiple FDANT dipoles can be mounted on a tower and connected with a phasing harness to form a high gain, stacked array system for enhanced coverage and performance.
What polarisation options are available?
The antenna supports both vertical and horizontal polarisation, providing flexibility for different installation requirements and RF propagation characteristics.
What is the maximum power handling capability?
The antenna can handle up to 75W maximum input power, making it suitable for higher power radio applications whilst maintaining reliable performance.
Is a mounting bracket included?
The mounting bracket is ordered separately, allowing for customised mounting solutions based on specific installation requirements.
What is the beam pattern of this antenna?
The antenna provides an 80° beamwidth in the E-plane, whilst the H-plane pattern is omnidirectional depending on the mounting distance from the mast structure.
What cable length is provided?
The antenna comes with 0.5 metres of RG213 cable terminated with a type socket connector featuring a protective shroud.
