quadrifilar helix antenna 137 mhz 3d models

Just my design of a Helix Antenna fpv antenna support for 5.8 Mhz. ...Super simple.

This OpenSCAD script generates a 2.4GHz "quadrifilar helix antenna". Dimensions are calculated using John Coppens' webpage http://jcoppens.com/ant/qfh/calc.en.php . The STL file has been reduced in Meshlab. Remember that this is experimental. At...

The 137 MHz Turnstile Antenna has been tweaked by I6IBE, Ivo Brugnera, to create a modified version of the original design. ...The document detailing this antenna's creation can be found at http://www.radioamatoripeligni.it/i6ibe/pdf/noaa897.pdf This...

I suppose that might have been good enough, but my ultimate mission was to create four antennas: one GPS L1 antenna for RHCP, one for LHCP, and then a GPS L2/L5 antenna for RHCP, and one for LHCP, and I was looking for lower losses. So I wrote the...

Support elements for building QFH antenna for 137 MHz. The parts are designed to fit onto 40mm diameter PVC pipe. Both STL and Solidworks files are provided. This project is a work-in-progress. ... # PVC Pipe Dimensions * outer diameter: 40.2 mm *...

These precision guides were engineered to craft a Quadrifilar Helix Antenna (QFH) using an infinite balun design tuned to 137.5 MHz for the NOAA 19 Satellite as described below: Original Build Guide:...

This is a remix of the Quadrifilar Helix Antenna by @jhsandell for 1090MHz (ADS-B) The following updates have been made: The 'bug' that jhsandell noted where the code was using diameters rather than radii has been fixed This version makes a...

This custom design empowers you to craft your own FPV antennas with ease, yielding smaller dimensions than traditional cloverleaf models and superior performance. I've personally tested them with goggles and a drone simultaneously, achieving a...

... for wooden rods and wire on top of it. ...Made as I didn't have aluminium rods and it was easier to solder the coax cable directly to the antennas. Made it easier for me to tune the antenna length to fit the 137 MHz, than having to chop aluminium rods.

A quadrifilar antenna is tuned to catch NOAA weather satellite signals at 137 MHz. In combination with an RTL-SDR USB radio dongle and software, these satellite passes can be recorded. The design was adapted from details found here:...

Created a custom jig for shaping lobes of a 5.8 GHz quadrifilar antenna as no suitable design was found online. ...This is a basic design, being relatively new to 3D modeling.

Here's a rewritten version of the text that meets all your requirements: We're building an antenna for 137 MHz, and we need to determine its optimal configuration. For starters, we'll use a vertical QFH setup with an aluminum rod diameter of 10 mm...

The 2.4GHz Quadrifilar Jig is a precision testing device designed to ensure the accuracy of frequency-tuned components used in high-frequency applications, including wireless communication systems and electronic devices that rely on radio frequency...

Simplified model of a 915 MHz antenna commonly used in UAVs

A basic dipole antenna operating at 433 MHz is created using a 6mm aluminum rod.

A Wi-Fi antenna, operating at 433 MHz frequency, is another name for an Antena de Wifi, ensuring seamless connectivity.

... screw. Check the antenna with a vector analyzer such as NanoVNA. For me, it had to be shortened. Items such as socket head screws, adjusting screw affect the SWR. For me, the antenna has been tuned SWR 1.0 at 433.500 MHz. ... VY73 de SP9MX

This is an external mount for a 1090 MHz ADB-S antenna. The antenna design itself came from this video https://www.youtube.com/watch?v=NZWY_eCBGXk and I decided I wanted to mount it outside for better reception. You will need: 1 x piece of coax. 1 x...
