WebSep 14, 2024 · A distinctive feature of the structure of the proposed antenna is a double folded loop antenna (DFL). The DFL antenna has a double loop antenna (one wavelength) and connection points at a quarter wavelength from the feed point. These connection points form a folded loop structure. 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.
