If you want a simple, inexpensive, and effective HF antenna for both home station and portable operations, please consider this end-fed halfwave project from the "Tech Minds" video channel.
The video does a good job of explaining the theory behind the EFHW, the pros and cons of the design, and the components needed to make this antenna work properly.
