Nooelec mesh antenna tuned to 1.4GHz for hydrogen line radio observing
This new antenna from Nooelec is tuned to 1.4GHz and designed for radio astronomy – currently not available on amazon.co.uk but is available on amazon.com
Currently listed as “Nooelec Satellite Mesh Antenna Bundle for Inmarsat, Iridium, & Hydrogen Line Applications. 20dBi Parabolic Antenna w/ 1.4GHz Center Frequency, 300MHz+ Bandwidth. LMR400 SMA Feed Cable & Mounting Kit”
One of the members of the SARA mailing list has stated that he has been able to identify differences during drift scan every 5 degrees although the design of the antenna show give beamwidth of 20 degrees.
The following is from Amazon (not my assessment):
- A reliable and high-quality mesh antenna set optimized to receive many L-band signals such as Inmarsat, Iridium, and Hydrogen Line (hydrogen’s natural frequency)
- 20dBi antenna is perfect for L-band applications where the antenna is stationary. With a centre frequency of 1.4GHz and a bandwidth greater than 300MHz, it encompasses many popular satellite applications
- Lightweight and durable design with high gain and low noise performance, ideal for outdoor applications such as satellite communication, remote sensing, and weather tracking
- The antenna is equipped with a sub-reflector for enhanced performance and features an SMA termination for easy connectivity to existing radio equipment
- The antenna is easy to assemble, and comes with an arm and coaxial cable attached to the arm for easy installation. Also included in the package is a versatile mounting kit that can be employed to cater to various installation situations
