I uploaded a triple shield passive loop that is a common monitor antenna for b'cast stations. I use it with a 15-20dB preamp for home entertainment. That gives a signal strength equal to my 160-meter

There's more that I want to add to the v2.0.6 update than just the Q calculation fix, mostly related to a configuration panel, plus some additional refinements to improve accuracy. Rather than wait

Start of reading Gentry¡¯s paper from page 26 to understand the matching technique proposed. Talking about the radiation efficiency for small antennas the value is low and there is no improvement

Locked Re: FW: [loopantennas] Optimizing Small Untuned Loop Antennas
Although Gentry uses the term "matching", I don't see his method optimizing the power transfer or achieving the impedance matching on either end of the network. It only generates the desired frequency

All, For an illustrative purpose you may read De Gentry's work about the broadband matching of a loop antenna but the calculated by him filter elements you cannot use because he designed his filters

Good morning Michael, If you google the thesis about" broadband matching of a loop antenna by De Gentry" you will get a lot of actual filters with values for the parts and a performance curve for the
