Antenna Links (EFHW, Dipole, etc)

I used these to build an EFHW for my QRP-Labs QMX. It is a 20m, 17m, 15m, 12m, and 10m antenna. If I want to use 10m I still deploy the entire antenna but disconnect the wire joint at 10m. The black section of wire that loops between the link is a 2mm barrel connector that comes apart disconnecting the rest of the wire only leaving the necessary length of wire to be tuned to 10m. The black is just heat shrink I used to cover each half of the barrel connector. Using these links does not allow you to only deploy the 10m or 12m ect sections of wire. The whole antenna gets deployed (roughly 34ft) and then I just disconect the barrel connector at whichever link I need to work each band. If you want to be able to deploy a shorter section of wire, let's say for 15m then you would want to use an S-biner instead of this link in that section. For example. I do have an S-biner at the very end of my antenna with a female 2mm barrel connector in case I want to later add 30m or 40m to the end.

K8MRD has a great video explaining how to build a linked End Fed Half Wave antenna. He uses S-biners but the concept is the same. I decided to make these because they are smaller, lighter, cheaper, and wind better on my small winder. https://youtu.be/qH2ed-Seg4M?si=Wfh1U1C1_HWoETyi

Ahhh ok, thanks for the clarity. Do you have a link to the barrel connectors you used. Much appreciatted, 73s

The winder is from K6ARK. It was a free download. He is also the one who designed and sells the transformer kit for the 20W EFHW transformer in the picture. I built it as a linked End Fed for 20m, 17m, 15m, 12m, and 10m.

Great! Thank you for your support! :)

Thank you! Simple is good. Not all useful things need to be complicated.
