loading coil 3d models

... wind 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 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...

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...

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...

Electricity is being transmitted to a device through a metallic cable as a human hand holds the end of it.

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

Loading coil form for use with an EFHW like the K6ARK kit.

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...

Free-standing manually adjusted loading coil form for amateur radio use on the HF bands. This will give a maximum inductance of about 19 microhenries and is designed to interface with standard 3/8"-24 antenna stud hardware, mounts, an whips. I...

A Medium-load coil spring is ideal for a novice designer, providing the right balance between support and ease of use. It's an excellent choice for those just starting in the design field as it allows them to experiment with different designs without...

Kind of tuning coil idea. Can be done manually or with some modification with a stepper motor. It's just an idea... 2 model to print with or without so-239 hole. Free to use!! But don't sell my designs! Made it for me and all the other...

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

Base loading coil for 80M band on a 12m Spiderpole using RG58 coax or 3/16 (5mm) copper brake pipe. ...Will update the information on this page when testing complete as i may require more turns on the former for my 1/4 wave, ground-mounted vertical...

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...

... all 7 sections extended, operates at 25Mhz. The loading coil at 22uh brings the operating frequency into the 40M band (7Mhz). ...It was designed to be 25uh total, so it can easily be fine-tuned by shorting out a few coils with a clip to one end.

The antenna features a loading coil that consists of two sections, with the upper section being tapped to provide separate connections for the 30 and 40 meter bands. The antenna is designed to be used with a 6m mast and requires a counterpoise that...

You will need two 2mm gold-plated plugs, which are typically used in RC car batteries, as well as 0.6-0.7mm enamel wire for the loading coil. The radiator should be approximately 5m long so that the coil sits about 1m above ground. To achieve...

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...

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

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...

By using a coil spring instead of disc spring, a coil spring with 4mm wire and a out dia of 16 mm has to be chosen, in order to meet the required trigger moment of 210Nm. Please ref. ...to attached calculation.

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...

OneTesla was having issues with their manufacturer, so they sent me the kit without the top load to get started while I waited for them to send the top load. I didn't want to wait, so I created this makeshift solution. It should be about the same...

Eine Top Last für eine Tesla Spule mit einem Innendurchmesser von 28mm. ...Sie Besteht aus 2 Teilen welche ich zusammen geklebt habe, da ich diese ohne Stützmaterial und ohne Metallische Gegenstände bauen wollte.

However, they don't look right without a typical top load of the big coils. This print is a toroidal top load for the smallest modules I found. If you search eBay with these texts below, you'll find them. I spray painted it with zinc spray, usually...

but they just do not look right without the typical top load of the "big" coils. This print is a toroidal top load for the smallest modules I found. eBay search texts below. I spray painted it with zinc spray, usually used for corrosion protection in...
