How to make a cardioid loop with a Loop Antenna Amplifier +
Recently I've been working on using a Loop Antenna Amplifier + to make a cardioid loop antenna.
I've already posted a few comments about it in one of the recent topics.
I've now written it up as a new web page with all the details, measured polar plot and detailed layout and how it works diagrams. You can click on the layout diagram to get a large size image ready for printing.
Is it worth making? Definitely yes, it's the best loop antenna I've made with a Loop Antenna Amplifier + and it has a far better signal to noise ratio than a conventional loop.
The best way to describe it is it's like using a HF Yagi on a tower but on LF and low HF!
