Loopstick antenna inductance. Enter transmitter power in watts: Enter antenna impedance (dominated by loop resistive loss) in ohms: Enter frequency in MHz: Enter loop inductance in uH: (Single turn loop inductance calculator here) The wavelength in metres is: The loop area in square metres is: The loop wire length in metres is: When made with a suitable ferrite core, the antenna gives excellent results over shortwave frequencies. The only thing I cant find online is a formula for number of turns specific to this type of antenna, because its so different from other types of antennae. Build a powerful long loopstick antenna for enhanced AM radio reception. Many of these are multi-turn loop antennas wound on a frame, usually square, some as small as 12 inches across. Dec 12, 2011 ยท Monday, December 12, 2011 Loop Calculations, Part 1 The Search for an Accurate Inductance Formula Mediumwave DXers routinely use passive antenna devices to enhance signal pickup to a portable or handheld AM radio. This is a common approach for constructing compact receiving antennas for AM radio. . I started this ferrite rod antenna project ( I call them loopsticks) by building a substitute antenna for the military AN-190 that is used with the BC-611 and the BC-1387 antenna coupling unit for directional finding duty. This universal product is compatible with various brands and is essential for achieving optimal performance and signal strength in radio communication setups. The number of turns of wire needed for the loopstick can be worked out from the single layer, air core inductance formula: Inductance = (radius^2 * turns^2) / ( (9*radius)+ (10*length)) where dimensions are in inches and inductance is in microhenrys. xzvdrjdrghuxvtwdfyvpquevmzzqtlvzkfsdivozkcuwqweemunshlakd
