The RFI YH03 is a 3-element Yagi antenna designed for directional communication in the 100–250 MHz frequency range. With a gain of 8 dBi, it is well-suited for both short and long-haul applications where controlled beamwidth and high front-to-back ratio are essential.

Features:

• The RFI YH03 antenna delivers 8 dBi gain for enhanced signal strength and directionality.
• This antenna maintains predictable beamwidths and a consistently high front-to-back ratio.
• The boom and elements are constructed from thick-walled alodined aluminium tubing for durability.
• The passive elements are one-piece and clamped with a unique wrap-around single bolt bracket.
• The radiating element is through-mounted onto the boom for structural integrity.
• All fasteners are marine-grade stainless steel with self-locking nuts to resist loosening from vibration.
• The antenna is supplied unassembled for easier handling and transport.
• It is quickly assembled using basic tools.
• The colour-coded elements and boom sections simplify installation.
• The antenna includes DC grounding on all elements for lightning protection and static dissipation.

Application Areas:

• The antenna is ideal for directional RF communication in both short and long-haul links.
• This antenna is suitable for systems requiring consistent and controlled radiation patterns.
• It is designed for use in outdoor and industrial environments where reliability is essential.

In the Box:

• 1x RFI YH03 3 Element Yagi Antenna (custom tuned)
