Come join the DARC for the April 2026 Lecture and Lab – In this lecture and lab you will build multi-band 6-40 meter end fed antenna that is fast and easy to setup and deploy and will support 100W. The build will take place at the Dallas Medical Center on the 3rd floor. Plan on attending in-person April 25, 2026 start time is 10am central time. More details below.
This is an in-person event and is open to the public you do not need to be a member of the DARC or have a HAM radio license to attend and participate or purchase a multi-band end fed antenna kit. We have a total of 20 kits available and they are first come first served on Lecture and Lab day and the kit cost is $20.00. Any questions or comments find us (KF5ZBL, KG5EIU) on the DARC Discord server or hit us up at: https://w5fc.org/contact/
This project creates a multi-band 6-40 meter HAM radio antenna that is uses a trifilar wound, 9:1 UNUN (unbalance to unbalance) toroid matching transformer that will match the high input impedance of an end fed antenna into the range where most antenna tuners can produce good performance. The antenna handles 100 watts of power. This antenna project requires an antenna tuner to achieve satisfactory SWR.
You will need the bring your solder kit assembly tools along with some other handy things to make the build go fast and easy:
Tools Needed/Required:
- Solder Iron, solder and associated accouterments to solder small electronic components
- Wire cutters, and strippers small screwdrivers and other general kit building tools
- volt/ohm meter
- Sharp box cutter/utility knife with a fresh blade
- X-acto knife with a fresh blade
- Needle nose pliers
- Safety glasses
Handy Tools To Have For The Build:
- Small files, emery/sandpaper
- Hot Glue Gun
- SWR Meter and tester
- Coax and a HF radio to play/test with (optional)
The antenna kit is a complete kit and includes everything to make a working antenna including the antenna wire and enclosure. If you don’t have the tools, don’t worry come on out and build anyway will have extras on hand. Special thanks to the EARC for their build instructions which can be found here.
