This has made small antennas more popular, despite some limitations. [Tech Minds] reviews the GA-450 indoor active HF loop antenna and finds it better than expected. You can see the video review ...

The antenna is built of two copper tubes. The tube used in the large loop, which forms a resonant LC circuit ... I've never used it for transmitting because my current amateur radio license doesn't ...

Generally, the biggest problem a new ham radio operator will come across when starting out on the high frequency (HF) bands is finding ... a magnetic loop antenna might be just the ticket.

We demonstrate that optimization of the small HF antenna's receiving-performance parameters, such as its receiving sensitivity and noise figure, are directly a function of optimizing the antenna's ...

Abstract: While the theory of operation and the procedure for measurement are similar for all loop antennas, the electrical and mechanical design of aircraft loop antennas differs considerably from ...

We have selected LMH6629 for one of our HF loop Antenna design. We want to work this device with single supply voltage ie 5V and dual stage with maximum total gain of 20-25dB for a frequency range of ...

I'm not going into details on how to construct a magnetic loop antenna. There's plenty of resources with info on how to do that, including online calculators that will give you all the needed info on ...
