Overview
This set includes all the components needed to assemble a 110° V-dipole antenna designed for NOAA weather satellite reception. The design allows for easy construction using readily available materials and provides a simple way to mount the antenna and protect your SDR.
Required Materials
5 mm steel rods, 53 cm long each (tuned for ~137 MHz NOAA APT).
RG174 coaxial cable (the thin type included with many budget SDR kits).
Three M3 screws for assembly.
Printing Recommendations
Print all parts at 0.2 mm layer height for proper fit and durability.
Included Parts
Two main antenna body parts for holding the steel rods at a 110° angle.
Two enclosure parts for housing the SDR dongle, designed to be lined internally with aluminum foil for basic RF shielding.
Features
Simple structure that securely holds 5 mm rods for stable dipole alignment.
Built-in 3/4" threaded-style mount, allowing the antenna to be placed on a standard tripod (no insert required).
SDR enclosure supports cable routing and shielding to reduce interference.
Notes
Lightweight, easy to assemble, and ideal for portable or backyard NOAA reception setups. For outdoor use, consider sealing the print or using weather-resistant filament.
