I am going to build a couple loop antennas to listen to some HF when we have the RV out next season. I have been researching designs and was wondering which is better a spiral loop antenna or the box style wrapped loop antenna. I have seen many of both but no discussion on which performs better or the differences in the way they act if any. I did figure out I can jumper out sections of a box design to change band range but then again as cheap as they are to make I could just make a couple different sizes of them.
On a side note when did variable air capacitors get so expensive Then again prolly 30 years since I have purchased one
