DIY Longwave and medium wave Directional LOOP Antenna

Hi, In this article, I will be documenting my design and build process (so basically also a guide) of my directional loop antenna for longwave and mediumwave DXing. So, as it is a tradition with my projects, before I start, I want to set some design goals. Basically, what should the final “product” behave and look like:
- Frequency range from 100 kHz to 1700kHz
- Directionality
- Rotatable base
- Fully remote controllable
- Easy build process
- Cost under 20€
Soooo, those requirements will be hard to satisfy. Mainly the “Fully remote controllable”. You might ask, WHY? I want to use this antenna along my WebSDR and because it is a loop antenna, it needs to be tuned, and I (or anybody else) must be able to tune the antenna without someone present at the shack to tune it for them :>…
Antenna itself
While I was doing the research for this project, I saw that most people were making these loop antennas from plumbing parts. For some reason, I don’t like it. I absolutly don’t know why, because both my PA0FBK Vertical and my QFH antenna for 137MHz meteosats (cool project btw) were built from standard drain (waste) pipe as the core of the build. I may reconsider this decision, but for now, I decided to build it out of wood.
