Building this project requires the use of tools that are capable of serious injury to you. If you attempt to build this project or something similar be sure you wear safety glasses and use all necessary safety precautions. If you are not familiar with the use of the tools required, obtain assistance from someone who is familiar with their proper use.
“It’s free, it’s open-source, it’s built for the Mac (written in Swift even!), and it hit 1.0 at the end of 2018 (I’m reviewing version 1.03).” Read more in the full article here. Record the reading of the water meter, and wait 15 minutes. Be certain no one uses any water during this time. Record the reading of the meter again. If the meter has recorded water use during the test, it might be due to a leak. Verify that the water use is not due to small appliances such as water filters, water softeners, or whole house. IINA has already hit a significant milestone–its 1.0 release–and we are grateful for the many thousands of users we have; doubly so for those who beta test our releases, provide feedback, and even contribute patches to make IINA even better. However, with 1.0 we would also like.

Project Background & Goals
There were a few goals for this antenna. The first goal was to be able to talk to some of my friends on a 6 meter link that is within easy radio reach of my home. Second was to be able to use some of the local 6 meter repeaters and third was to be able to use single side band when the band opens. For FM operation vertically polarized antennas are standard. So this antenna should work well for FM.

For single side band it is really best to have a horizontally polarized antenna which this antenna is not. Using an antenna that is crossed polarized from other stations in your area results in about a 20 dB loss in signal strength. If the band is open and you are receiving signals that are bouncing off the ionosphere then polarization is not so important since the polarization tends to get mixed up. Another consideration is that the radiation angle for a quarter wave antenna is pretty high and will not be as good for DX signals as compared to an antenna the has a lower angle of radiation. At some point I will build something else that is better suited for sideband, but for now having an antenna that is vertically polarized is better than nothing on sideband.

Motrix 1 4 15. Another consideration was the gain of the antenna. I wanted something that was small and relatively easy to build. I was not as concerned about putting out the most potent signal. Since this is a quarter wave antenna it is considered a unity gain antenna as compared to a dipole '0 dBd'. Quarter wave antennas are pretty simple and do not require any matching circuitry when fed with standard 50 ohm coax.

A couple more considerations were materials and level of mechanical complexity. I wanted a design that was fairly simple but mechanically strong enough to stand up to the weather. I live in a relatively moderate climate so I did not have to worry about snow or ice loading. The design just had to stand up to rain and wind. I knew that I wanted to make the radials out of aluminum rod but other than that my design was open to whatever material I could find.
