I made this stand for small, self made 868MHz antennas with an RG316 cable attached. ... The cable may be fixed with zip ties to the stand, but the slot is tight enough to hold the cable w/o additional zip ties.

I'm excited to share my latest project, a cutting-edge 3D printed antenna specifically designed for use in Amateur Radio Direction Finding (ARDF) receivers. ...Check out the technical details and specifications at...

I ordered some custom antenna insulators using a 3D printer that makes plastic items. Since I wanted to add a personal touch, I had my call sign embedded into them. To make things easier, I created a single ZIP file with all the necessary files...

This is a simple mount i made to hold a cb antenna to a rv ladder. The one i made is still going strong 1+year later. Instructions Print, Cleanup any supports used, assemble and enjoy. ... If you like my designs, please consider Bitcoin...

Make your cheap antenna switch. ... PCB design link: https://drive.google.com/drive/folders/1Yk5KqoF289jlCbTLUHok6m3GpXgQ20CO?usp=sharing Here you can buy ready-made PCBs:...

The handheld device is a compact Antenna Reel that stores and releases wire. ...It usually consists of a spring-loaded coil of insulated wire that can be extended to a desired length by unwinding it from its storage position, and retracted back into the...

Takeoff Projects helps students complete their academic projects.You can enrol with friends and receive antenna projects kits at your doorstep. You can learn from experts, build latest projects, showcase your project to the world and grab the best...

... for rust-sensitive metals. ...My TV antenna has already broken twice. It will probably happen again, but I thought of this plastic bracket to give it a second life.It requires two zipties and four 4.8 x 19mm screws. ...Probably better stainless.

An antenna extention for DJI frame so u can protect your transmitter. U need an extention lead for this to work, glue this print in the arm with hotglue. Preferable its printed in ninjaflex to make it work even better. ... ...

Mounting hardware for IBCrazy's Vee antenna is being improved rapidly. v0.2 Version Enhancements: Gap between components increased to a generous 3.5, accommodating support rods designed like coffee stirrers perfectly. Two extra lateral supports...

I visited several local ham radio stores but couldn't find any suitable spacers or isolators for my longwire antenna at home. That's why I decided to design one myself using Fusion360. After selecting the correct infill pattern, you can simply print...

The DIY enthusiast constructed an antenna tower using PVC pipes, SMA extension cables, and intricately designed 3D printed components. Winter poses a significant challenge for quadcopter pilots, as the cold temperature causes fingers to stiffen,...

Conclusion: Building your own helical antenna for 5.8 GHz FPV goggle is a fun and rewarding project that can greatly improve your FPV experience. With these simple steps, you'll be able to create a high-performance antenna that will give you the...

... ...It might not fit every antenna perfectly, but I designed it specifically for an antenna with a 42mm wire and a 90-degree plug. ...The design sticks securely to the plug end, while a single small zip tie keeps the wire in place to prevent slippage.

I was tired of fiddling with the nuts of the fpv-antennas on my skyzone 04X, as the two antenna-sockets are somewhat close and/or my fingers are somewhat big. So I designed a ring made of TPU that snuggly fits onto the hex but is made from TPU so it...

Since I reside in a community governed by HOA regulations, installing antennas for my radios is strictly prohibited. Nevertheless, no one has explicitly stated that I cannot utilize the antennas mounted on my vehicle. The only catch: remembering to...

This allows for precise directionality, enabling the antenna to be pointed towards weaker signals for improved reception while eliminating stronger, more annoying signals. The larger ring is constructed from a 10mm wide cable channel, with 18 turns...

... printing procedures. The spool cover is designed to slide smoothly over the antenna wire, preventing it from unwinding accidentally. ... To achieve the desired outcome, I set my hotend temperature to 245 degrees and my build surface at 90 degrees.

I used plastic coffee stirrer's as antenna mounts for just about anything, and they worked surprisingly well. Making some with printable tubes proved to be a great alternative. The entire project was printed in PLA, which provided excellent...

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:...

Assemble four of each two tower pieces using the tower clips on their legs, while antenna dishes also feature clips at the back for added stability. Attach spheres to assemble a radio telescope (http://www.thingiverse.com/thing:15183). ...The OpenSCAD...

This adapter is specifically engineered to fit snugly around the Du-Bro antenna tube, identical in design to the #2345 model. A precision-drilled hole offers an optimal starting point for expanding to accommodate a 1/8" drill bit, ensuring a seamless...

A Triforce-shaped ornament for your car's antenna, available with 4.5mm, 6mm, and 8mm holes; make sure to measure the top of your antenna! ...If you'd like a more secure fit, there are "insert" versions of all hole sizes, which allow you to pack the...

Obviously this kit can be used also to build random wires antennas by changing the toroid type and the winding ratio, the GND connection allow use of counterpoises. For examples and tutorials about EFHW winding and details visit section...

Just as a dipole antenna can pick up radio waves and convert them into usable energy, our bodies absorb light, sound, and other forms of electromagnetic radiation, allowing us to perceive the world around us. In fact, research has shown that the...
