137 mhz weather antenna. The KE-137 is a quadrifilar helicoidal (QFH) antenna.
137 mhz weather antenna. 1Kg Frequency: 137 MHz Mast Diameter accepted: 25-62 mm Connector: MJ (SO-239). Receiving antenna for weather satellite NOAA & ACARS Features: Length:1. 0m / Weight:1. Presented V-dipole horizontal plane antenna is a simple DIY project that will deliver good results in receiving the 137 MHz weather satellite transmissions. Over the years he notes that he's received a number of questions asking to clarify the design This is where the QFH Antenna comes in, it's actually two antennas, a small one inside a bigger one, that is of the proper dimensions so that it blocks out surrounding interference and receives signals very well on the 137. Two horizontally mounted crossed dipoles are coupled through a phase shifting network so that true circular right hand polarized reception is achieved. One beneficial aspect of this Double Cross antenna is that it is quite tolerant of construction variations. To receive Weather Satellite images, you will need an antenna (like the UC-1374-531R), a sensitive VHF receiver capable of FM signals from 137. Apr 8, 2025 · With our RTL-SDR Blog dipole antenna set, it is possible to use it in a 'V-dipole' configuration to receive polar-orbiting weather satellites such as NOAA and Meteor at 137 MHz. Mar 13, 2016 · March 13, 2016 Building a simple NOAA APT Antenna out of an Umbrella In order to optimally receive NOAA weather satellite images a special satellite antenna tuned for 137 MHz should to be built. The antenna here is made of 2 telescopic whips and 1 PCB, and the assembly is very easy, just put the 2 antennas onto the PCB and hold them with cable ties. Our crossed dipole antenna KX-137 offers best conditions for an optimal reception of the polar orbiting weather satellites in the 137 MHz range. Mar 1, 2017 · Over on his blog Adam 9A4QV (seller of various RTL-SDR related goods including the LNA4ALL) has just made a post detailing a build of a high performance super simple NOAA/Meteor M2 weather satellite antenna. Very Small and Portable with SMA Female Connector. Circular polarised antenna for reception of NOAA weather satellites on 137 MHz, or ACARS transmissions on 135 MHz. 5 MHz frequency band that the NOAA satellites transmit around. Dec 29, 2020 · Back in 2017 we posted about Adam 9A4QV's simple V-Dipole antenna design which works very well for receiving NOAA and Meteor weather satellites at 137 MHz. Generally either a QFH or turnstile antenna is recommended as these receive signals coming from the sky very well. The KE-137 is a quadrifilar helicoidal (QFH) antenna. 0 to 138. 0 MHz with an audio output (earphone jack), WXSAT software (freeware available) and a computer. TURBO-TENNA WX-137 SERIES 137 MHz WEATHER SATELLITE ANTENNAS Thumbnail Picture - Click to Enlarge The WX-137 series of antennas are marine-grade 137 MHz circularly polarized antennas designed to receive weather satellite images from the polar orbiting NOAA and Meteor satellites. Jul 3, 2020 · Nooelec UWB Surveyor Antenna - Extremely Wide Bandwidth Biconical Low-Profile PCB Antenna. All performed test delivered very good and excellent pictures despite using a home depot cheap materials and hand tools. This type of antenna is a lot easier to build compared to a QFH or turnstile, and it results in good performance if built and set up correctly. Frequency Range of 700MHz to 10GHz, Average Gain of 3dBi. That is, an antenna in this configuration will almost always work well even when the dimensions are only close to the optimum design. yzsgnvxhsitntrhoczfwmfjslsqzmgphfctuzxluhgvuikhort
