antenna loading coils 3d models

Multiband antenna loading coil printing guide: Stand the coil upright with the SO-239 hole at the bottom. Print two pole mounts at once while laying them down. The coil is wound with aluminum fence wire, using crimped terminals. A 5m / 16.5ft...

... a coil of wire around a 2" PVC pipe. ...This can be used as an adjustable loading coil for a vertical antenna. With a 109" whip on top it should support up to 80m. ...The design was inspired by the coils on this page: https://w0bnc.com/loading-coils

This is a minor remix of the nicely-designed loading coil by SA2CLC. I changed three holes to a slightly smaller diameter, so a #10 screw would fit nicely. ...

This is only the mounting points to wind a coil of wire around a PVC pipe of any diameter.

Made this for converting an old CB antenna to HF. The inner diameter is 35 mm. If you make a threaded brass rod and make a wheel on it. Could you do manuel tuning for the different bands. Kind of tuning coil idea. Can be done manually or with...

The pitch between windings is 3 mm.If you want to create a loading coil for a multi-band vertical antenna, you can calculate the needed inductance using an online calculator for a loaded vertical, and then input the necessary data into the Coil 64...

I utilize a specialized holder to keep the ends of my extended FrSky receiver antennas at precise right angles for optimal drone performance.

(these parts can all be bout as a set used for mounting CB antennas such as this (remove the plastic insulator ring parts): https://www.amazon.com/dp/B000X380KQ/ - For mounting the bottom of the coil to a standard stud antenna mount, a second set of...

This is a form for making the coil for base or center loaded HF vertical antennas. It's intended for QRP work, although I suspect it would take a fair amount of power. Construction is straight foreward, just wind your chosen wire round the former...

I used this calculator on the web.https://www.66pacific.com/calculators/coil-shortened-vertical-antenna-calculator.aspxOnce the Microhenry is know. I used kit and parts calculator to determine turns on the toroid.I used a t50-6 but you could...

Extension with Loading Coil for MFJ-1979 (as vertical or double for dipole). ... additional ABS (fi:30mm, length:100mm) with Zn threated bar (M8, length: 180mm) for mouting

A loading coil is designed for the fold-up PRC Antenna pictured. This antenna is very lightweight and when horizontal it only droops about 4 inches. It's 113.5 inches long (2.88M). The AT-271 "Fishing Pole" antenna was used on the PRC-25 and PRC-77...

Coil acts as both a loading coil for 80-meters and a "trap" thanks to it's internal capacitance, so adding it to the 40-meter band half-wave element will not change the tuning on 7 MHz and above. -Use 20ga. enamel coated magnet wire for windng...

The result obtained from the website https://m0ukd.com/calculators/loaded-quarter-wave-antenna-inductance-calculator/ was a coil with an inductance of 207.65µH, at https://m0ukd.com/calculators/air-cored -inductor-calculator/ to have a coil with...

In that spirit am I appealing to all the inventors, to all the hobbyists, to all the makers, the designers, the engineers and the tinklers, PLEASE use the freely provided STL files to 3D print your own STA (Spacetime Antenna) coil and to conduct...

Low-Tilt Collar for Wolf River Coils (WRC) Silver Bullet (SB) Mini - keeps the contact aligned with the coil windings more precisely than the stock collar. Large hole is threaded, but may need to be cleaned with a 1/4-20 tap to enable insertion of...

This plate is a vital component, used in pairs, to secure a PVC pipe (bottom) loading coil onto a MFJ-1910 33ft or similar fiberglass antenna pole. It takes the place of the original adapter due to its inside diameter being slightly too small,...

***This is a work in progress*** This is the second version of an HF loading coil I built. This version is designed to sleeve over a 1.5" piece of PVC pipe for the greatest support. My first design was entirely 3D printed, and obviously, the layers...

This is my prototype version of a DIY Loading Coil for HAM Radio. (UNTESTED)It is a glue together design for the 3 main coil parts (bottom_coil, main_coil, and top_coil). The coil caps, and radial ring can be screwed on and off via the printed...

An integral component of a frequency-emitting circuit is the coil antenna, which plays a significant role in transmitting radio signals.
