For this project, we will be building a 6m Delta Loop. In the past, I have not had much interest in 6m. Most of my time is spent 15-80m. Several friends of mine are always talking about it being the “Magic Band”, so I figured I would get an antenna up.
I wanted to do something different than the standard ground plane or dipole. After looking around on the web I decided to go with a Delta Loop. My antenna is based off a design found on the site CQHQ. I found the way the matching section was set up interesting. Instead of just attaching a piece of 75 ohm cable, it is wound on a form made from PVC pipe. The lengths were not recalculated from the original post. If you would like to calculate your own frequency, I have linked an online calculator at the bottom of the post.
It is easier to do this before wound on the form.
Only one quick test was done on the 6m Delta Loop. Tuning will be required. The antenna was resonant around 48 mhz. This does not come as a surprise. Typically, I cut my antenna a little long to make it lower than the desired frequency. This insures that adding wire to the loop will not be necessary while tuning. In a future post we will tune and test this antenna.
