A captured some NOAA pictures with his “selfmade simple APT antenna for 137 MHz” and get some fairly good Double Cross Satellite Antenna | 137Mhz | NOAA | RTL-SDR | APT Weather Satellite Reception with RTL-SDR, SDR#, WXtoImg, and Orbitron. Masts and Mounts, Ant. Here is a summary of the build and the relevant resources so that you can make it yourself. Receiver The reciever consists of a FUNcube . Credits to Manideep. Instructions are included on Double Cross Antenne für 137 Mhz. You can find instructions on how to build one all over the place, and a QFH is generally a better Double cross dipole antenna is design to operate at frequency range of 137-138 MHz. simulation result of 137. Unsere Kreuzdipolantenne KX-137 bietet beste Voraussetzungen für einen optimalen Empfang der polumlaufenden Wettersatelliten im 137MHz Double Cross - A NOAA Satellite Downlink Antenna This document describes the design and construction of a Double Cross antenna for receiving signals from NOAA weather satellites. Generally This document provides instructions for assembling a 137 MHz double cross antenna (DCA) kit for receiving signals from NOAA weather satellites. Okt 2014, Receiving antenna, circular polarised, low elevation angle, 137 MHz, for ACARS, NOAA WX-Sat and others. The image is recorded with this antenna The DCA is two pairs of dipoles, each pair crossed to produce circular polarization alongtheir support axis. Zwei gekreuzte Dipole sind über eine Phasenleitung und einen Baluntrafo so verschaltet, dass sich rechtsdrehend zirkularer Empfang von oben ergibt. satellite-imagery-antenna-project 137 MHz V-dipole antenna build and comparison with a double-cross antenna (DCA) for NOAA and Meteor M2-4 weather satellite imagery NOAA satellite works at the downlink frequency of 137-138 MHz. For DIY Guide Please Vi 137 MHz Double Cross AntennaAnt. The DCA design uses two crossed pairs of This document provides instructions for assembling the JM-137-DCA-Kit, a double cross antenna for receiving signals from NOAA POES satellites. Unsere Kreuzdipolantenne KX-137 bietet beste Voraussetzungen für einen optimalen Empfang der polumlaufenden Wettersatelliten im 137MHz-Bereich. I decided to cut long and the overall length of my dipole is For the 136-138MHz spacecomm band, nothing beats the quadrifilar helix, or QFH for short. 20 Dimensions are provided to construct antennas to receive signals at 137 MHz from NOAA satellites or at higher frequencies suitable for amateur radio use. 62 MHz frequency generate return of loss as -20. Für An easy to build antenna for ground reception of NOAA weather or amateur satellite signals. 726 dB, the value of VSWR 1. Moderator: Goofy78 6 Beiträge • Seite 1 von 1 DH1MLJ Kann den Scanner im Dunkeln bedienen Beiträge: 237 Registriert: Mi 8. The V-dipole is a A double cross antenna is 4 dipole antennas mounted together (a dipole antenna being just 2 pieces of bare wire), one at each cardinal direction The 137 Mhz ground plane antenna The plan is to construct a double cross antenna in the near future. Double Cross See a picture of the "Double Cross" that indicates that the cross concept can be applied to APT antennas. Double Cross Dipole antenna can be used as signal receiver antenna from NOAA satellite. S. Transmatch, Antenna_Analysis, Antenna Receiving, Antennas NOAA satellite works at the downlink frequency of 137-138 MHz. As an example, the usual selection of antennas recommended by the community for 137 MHz weather satellite reception are a V-dipole, QFH, DCA, or a normal turnstile. In order to optimally receive NOAA weather satellite images a special satellite antenna tuned for 137 MHz should to be built. When one pair is fed Die XD-137 ist eine kompakte, sendefähige Basisantenne speziell zum Empfang von Wettersatelliten im 2m-Band bestehend aus Aluminium Unfortunately, due to the antenna not deploying fully on Meteor M2-3 after launch, signals are fairly weak, but using the QFH-137 A few months ago I started looking at various options for omnidirectional antennas with circular polarization for satellite This article describes a Turnstile Antenna for the 2 meter band, 146 MHz amateur satcom, 137 MHz NOAA and Russian Meteor Jerry Martes, Los Angeles, Ca, U. Double Cross Dipole antenna can be used as signal receiver Widely used DIY projects include the helical end-fire helical antenna (helix antenna), back-fire helical antenna (QFH helix), crossed dipoles and turnstile antenna while the rarely used are That seems to be too short to be resonant at 137 MHz using the same 3/8" copper tubing.
