NOAA Satellite Signals With a PVC QFH Antenna and Laptop : This instructable covers everything you'll need to get started in being able to receive the APT (Automatic Picture Transmission) signals from the NOAA Satellites (NOAA-15, 18, and 19) flying overhead (and can be a foundation for listening to other s…

2022年11月22日 · The Quadrifilar Helix (QFH) antenna, with its unique design and circular polarization, ensures efficient NOAA satellite signal reception. This article explores the history, key characteristics, and practical modeling of QFH antennas using AN-SOF, providing valuable insights for RF engineers and enthusiasts.

2020年3月7日 · With something like the NooElec SDR dongle, a computer, and a QHF antenna you can predict your own weather, even if all other forms of communication are not …

2024年12月1日 · Crafting a PVC QFH antenna was a rewarding challenge that has brought me closer to the wonders of satellite communications. The NOAA satellites continue to send their data from space, and thanks to this DIY antenna, I can now capture stunning weather images whenever they pass overhead.

This odd looking thing is a quadrifilar helix antenna and it's specially designed to receive images from the NOAA weather satellites. It's actually two antennas that are formed by a larger loop and a smaller loop.

2017年3月1日 · Most antenna designs for polar orbiting weather spacecraft are based on circularly polarized turnstile or QFH designs. However, Adams antenna is based on a very simple linearly polarized dipole, which makes construction almost trivial.

To receive images from NOAA satellites, I've built myself a QFH-antenna out of copper tubing. Whilst building I had trouble finding useful information on how to do it exactly...so here is my way of doing it :D

One of the two QFH antennas on NOAA-17 (Photo courtesy and (c) Lockheed Martin: The quadrifilar helicoidal antenna - quite a mouthful - is easy to construct (even though it does look complicated), and the results are excellent.
