end fed half wave antenna 3d models

This is a box for an End-Fed Half-Wave antenna. Following Steve Ellington's 64:1 design, I used binding posts for both the ground and the long wire. This uses standard Binding Posts as well as a Chassis Mount SO239. Everything should be snug - the...

This is an end fed half wave case/winder which was designed to fit a T140-43 toroid wrapped with 18 gauge Magnet Wire. This will fit a BNC adapter. ... Plenty of changes to come as well as a better description

This compact enclosure is designed to house a matching transformer, capacitor, and PL plug for use with EFHW antennas or Fuchs antennas, drawing inspiration from the QRP Guys' mini 80m 10m no tune end fed half wave antenna.

... ... Should fit all 240 size torroid rings....I have a hole made for the so-239 and main wire...I don't need a mount for a counterpoise for the end fed half wave I made so I didnt include a mounting hole for that. If you need one easy to drill it out.

I've matched my LC circuit for a 15-meter High Wire Efficiency Factor (HWEF) antenna, comprising nine turns of 0.65mm copper wire and approximately 20cm of RG58 cable, achieving a Half Wave End Fed configuration with an impedance of about 3.5k ohms...

Half Wave End Fed Matchbox for 10 meters to 40 meters. Center of operation: the FT-17 ceramic coil core, specifically the FT140-37 version, is a suitable option. ...It can handle signals as strong as 150 watts in SSB mode.

A 49:1 Unun built to [K1RF's specifications](http://gnarc.org/wp-content/uploads/The-End-Fed-Half-Wave-Antenna.pdf) with a FT140-43 should be good for 15 watts digital, 37 watts CW, and 60 watts SSB. That said, I have yet to push more than 10 watts...

I needed a solution to add strain relief to my end fed half wave antenna. To achieve this, I threaded wire through the end until it emerged on the other side and then secured it tightly using two bolts inserted from the side. The setup is easily...

Build your own wire winder, end fed half wave, antenna for ham radio, or something. This is an SO239 version, I suggest a 60 percent infill with PETG, but I'm not your mother. I also have a BNC version if needed. ... How to build out the rest...

Quick 50mm spool for a fishingpole antenna

Portable version of the matching unit housing for QRP EFHW antenna. I used two stacked FT50-43 ferrite cores, with a wound autotransformer circuit with a 49:1 ratio. For winding I used enameled wire with a diameter of 0.7mm as you can see on photos.

This is an initial take on a secure end-fed dipole antenna housing.

The same parts can be used, minus the capacitor for a 9:1 random wire antenna. All windings are radial, with no crossover across the toroid because of the center support post. The 49:1 was wound using 3 primary, 21 secondary winding. Two separate...

Housing EFHW balun 1:49 (2/14 or 3/21) with space for a choke balun. Dedicated for FT 140-43 toroids. Similar cases in the photos. The best version in the file in my opinion. ...

End Fed support for 240 size toroids, suitable for EFHW antennas. - 2 versions available for BNC or SO239 connectors - the spool can easily accomodate more than 20 meters of AWG20 wire, to build a full size 10-15-20-40m EFHW antenna - easy to build...

... ... This includes a support and connection for both the horizontal / sloping antenna wire and a vertical (hanging down) counterpoise that may be grounded. ... My printer setup and upgrades can be seen here: [cockrum.net](https://cockrum.net/)

Housing for a 1:49 (1:56) UnUn based on an FairRite 2643251002 toroid to use with End Fed Half Wave Antennas

Simple end-fed random wire/half wave antenna mount Suitable for SO239 connector plenty of holes for strain relief and mounting Reference for building https://www.hfkits.com/manual-19-unun-600-watts-for-long-wire-antennas/...

For more information on the design of this antenna system, visit the Facebook group dedicated to "End Fed Half Wave Antennas." This innovative design has been meticulously refined by Steve Ellington, N4LQ, and is now available for public use. A...

This is a frame for an End Fed Halfwave Amateur Radio HF antenna with a built in antenna winder. The purpose of this is to convert a 50ohm feedline (coax) to approx 2000-3000ohms which will allow a halfwave piece of wire to transmit/receive on...

End Fed Half Wave antenna is my favorite choice for portable operations. It's a resonant antenna, easy to deploy and free of RF issues (that usually are found on similar random wires setup). Since I operate mostly with low power, around 30W maximum,...

Micro End Fed Half Wave antenna for QRP The toroid housing can be removed from the spool and directly connected to the radio with BNC-BNC male adaptor, cables, etc. Bill of materials: - FT-82-43 toroid (with 49:1 winding ratio) - BNC female...

PETG/ABS recommended (temperature resistance) Assembly: See pictures Winding the torroid: 2 bi-filar (twisted) primary windings and 8 + 8 secondary (1:64 transformer) For more on the winding and theory of end fed half wave antennas see here:...

This is a central component of a high-Z end-fed antenna crafted at the Youngsters on the Air YOTA 2016 workshop in Austria's Wagrain region. Wolfgang, OE1WBS (www.wbsfilm.at), designed this assembly. For additional information, visit...

This is a fresh approach to a balun enclosure for the High-Z End-fed antenna from Yota, boasting an innovative design that diverges from previous iterations. Construction-wise, it's strikingly similar to its counterparts, with each step echoing the...

The EARCHI group's popular homebrew Ham Radio HF antenna project is a 9:1 UnUn for an end fed antenna. This project can be built using the published plans and a T130-2 Toroid. The EARCHI group sells these devices, but they also offer free...

This design is tailored to house a T106-2 toroid to build a unun similar to the Earchi 6-40 end fed antenna (https://earchi.org/92011endfedfiles/Endfed6_40.pdf). The necessary hardware includes: * A T106-2 toroid * Three 20in lengths of 20 Gauge...

The antenna is basically the same design as described by VK3YY at https://vk3yy.wordpress.com/2014/08/31/end-fed-for-40m20m10m/. The 3D-printed parts allow, however, for a much lighter version with better handling. You need to print the following...

Small fitted box to hold an end-fed half wave antenna transformer made on one FT140 size toroid core. 10mm D-shaped and countersunk hole for panel mount BNC connector. 4mm holes sized for #8 hardware to make the antenna and ground connections. ... ...

This is a simple spacer for 6 wire cage antennas. The 3mm holes should be fine for 18 ga insulated wire. After threading the wires through and drawing them taught, position the spacers and put a drop of super glue where each wire passes through...
