text: Since antenna size is measured in multiples of wavelengths, a halo antenna with sufficient capacitance to operate at half its design frequency will function as a small loop[citation needed]; likewise, a small loop fed with a signal at approximately double its maximum design frequency will function as a halo antenna, if its reactance can be tuned low enough to resonate, or the excess reactance removed by a matching unit.
