The Halo Loop is an ultra-compact and lightweight antenna for VHF and UHF. There are a number of loop designs out there, and to distinguish this one, I’m going to henceforth refer to this loop as in the title above: the Noise-Cancelling Passive Loop (NCPL) antenna. These may include units with amplifiers or switched “tuning circuits”, and frequently VHF rabbit ears are included. The practical upper frequency limit for a true and efficient small loop appears to be about 60 MHz. There are a few basic construction methods for wire loop antennas: stiff wire (mostly self supporting) strung wire (on a framework of some sort) hung from trees, masts, or other supports None of these need to be particularly difficult to build, although multi-element versions at HF can be mechanically complex. Definition A full wave loop is, as the words imply, a continuous loop of wire or other conductor approximately one wavelength long, usually with the two ends of the loop connected to the feedline. UHF wavelengths are less than a meter, so loop antennas (antennae?) work fine. At the other extreme, very large wire loops offer possibilities for HF operation on a number of different bands. Has anybody found a good tutorial/analysis of what needs to be done to make a resonant loop antenna for UHF or L-Band frequencies? I know that the thickness of the wire starts to have an effect, but it's usually merely mentioned and no real quantitative discussions happen as to how to modify the antenna design for wire thickness. The following five picks represent reliable indoor and outdoor options with strong reception, long range, and easy installation. 99 A fairly in-depth look at using highly frequency-selective, small-loop antennas to create improved radio receivers.
