Readytosky Triple Feed Patch Antenna (SMA)

The Readytosky Triple Feed Patch is a directional 5.8 GHz FPV antenna designed for long-range cruising, freestyle penetration, and ground station setups. Based on Maarten Baert's open-source design, this high-gain PCB array delivers exceptional axial ratio and clean signal reception, making it a reliable upgrade for FPV goggles and external diversity video receivers.

Key features

• High directional gain of 9.4 dBi with a 55° half-power beamwidth for extended video link range and obstacle penetration.
• Dual-port layout allows operation in either RHCP or LHCP polarization by shifting the feed connector and the included 50-ohm dummy load to the opposite port.
• Wide operating bandwidth from 5.47 GHz to 6.13 GHz, cleanly covering all standard analogue and digital 5.8 GHz FPV channels.
• Manufactured with tightly toleranced PCB material to maintain an axial ratio below 1.3 across the main radiation beam.

Specifications

• Center frequency: 5.8 GHz
• Bandwidth: 660 MHz (5.47 – 6.13 GHz)
• Gain: 9.4 dBi
• Half-power beamwidth: 55° (horizontal and vertical)
• Axial ratio: < 1.3
• Radiation efficiency: 83.5%
• Polarization: RHCP / LHCP (switchable via port selection)
• Connector: SMA

When mounting this patch on your FPV goggles or diversity ground station, pair it with a 360-degree omnidirectional antenna on your receiver's secondary channel. This ensures solid coverage when flying behind or close to yourself while allowing the triple feed patch to lock onto distant signals in your forward flight path. Ensure the 50-ohm terminator is firmly threaded onto the unused antenna port before powering up.
