Folded loop antenna
WebKeep the antenna as high off the floor as possible. (As with most antennas, the more height, the better.) For indoor operating, however, most hams recommend using low output power. You’ll avoid RF “bites” as well as interference to VCRs, TVs and so on. Many hams have been successful operating indoor antennas with just a few watts output. http://earmark.net/gesr/loop/foldloop.htm

WebDescription The 3-D Folded Loop, or simply the 3-DFL, is a one-wavelength loop that is reduced in height and width by being folded into three dimensions. A 28-MHz loop that …
WebThe feed point impedance of a full wave loop antenna is theoretically in the vicinity of 120 ohms and requires a 2:1 impedance transformer (for single band loops or a 4:1 balun to match on multiple bands) with 50 ohm line. ... 500/1500 Watts, OCF, Loop, Folded Dipole Antennas. Bullet Hybrid (4:1) HF Balun + 1:1 Choke, 1.8-61 MHz, 500/1500 Watts ... WebHowever, as the folded dipole is relatively small (< 0.75λ) to the wavelength, it is not a true travelling-wave antenna like a Rhombic or Beverage. The feedpoint impedance at resonance. Standard recommendations for the dimensions of a folded dipole are based on the lowest operating frequency (MHz min), i.e., the largest wavelength λ max: Ref. 1:
