Thank you Shannon. This is perfect. I will check the magazine for details.

The article has you mark the antenna for the right spot for each frequency, but if you have a tuner in your setup, you can extend it all the way, tune it, and it will work well without the manual adjusting. I have a backpack and a PVC tube I use to make it all portable.

My idea was to use some mount(yet to figure this out) in the backyard, run the cable inside the home when I want to use HF. In addition, when I am visiting some park, planning to mount if using some mag mount. I don’t have much of a backyard and wanted to see if this antenna can be used at home and when I am visiting places. With this info, I have few questions. Please bear with me as I am absolutely new to Ham and might ask dumb questions. While reading, one thing I realized is that, the antenna depends on the bands I wish to use. Well, at the moment, I want to start with something that can get me on air for commonly used frequencies where I can listen in and learn how to use the radio. At the moment, all I have is a HF transceiver with builtin tuner.
