The Vari-Loopstick Antenna Coil. There are several different loopstick antenna coils listed in electronics catalogs and it is necessary to buy the right one to use in assembling the radio receiver with crystal-diode detector. All the loopsticks specified in the list of parts and materials have been tested in building models for this book. These loop- sucks haveÆZ "Q" or quality factor of at... The coil will slide along the ferrite rod. There is about 1.5 inches of space available on the ferrite rod when the coil is all the way to one side.

27/06/2017 · Hi. Frequently, read that antennas are generally as good for receiving as they are for transmitting. Plain AM radio receivers (300m band / 1MHz) use mostly ferrite rods with a wound coil as antenna for reception, that gets nearby stations during the day and can receive long distances at …... 29/11/2018 · By loopstick, I assume that you mean the item that we call a "ferrite rod antenna". If you want to receive 100kHz, then the antenna should be resonant at 100kHz. If it is resonant at some other frequency, the wanted signal will be attenuated.

The Vee antenna is another field expedient, directional antenna. It consists of two wires forming a Vee with the open area of the Vee pointing toward the desired direction of transmission or reception. To make construction easier, the legs may slope downward from the apex of the Vee (this is called a sloping Vee antenna). how to make essiac tea for dogs radio that uses a built-in loopstick antenna. The loopstick (see insert) is an inductor wound The loopstick (see insert) is an inductor wound on a ferrite rod, usually …

27/06/2017 · For a small loop (or just about any type) antenna the only thing you can do is to make it larger because radiation resistance mainly depends on geometry (EM wave phase difference across physical free space vs the electrical "shorter" size of the antenna at the frequency) of the antenna with the 'best' loop being a single loop cut and tuned to the correct frequency. how to make wifi antenna for android phone The antenna - ground portion is 30 turns #28 gauge wire about 1/8" from the primary. The original coil in the Morgan book was probably smaller, with smaller gauge wire. The original coil in the Morgan book was probably smaller, with smaller gauge wire.

How To Make Loopstick Antenna
Just wind it normally with small litz at one end or make it latice wound. Some of the better antennas were space wound and the wire covered the whole antenna.
- 30/01/2011 · The Twin Coil Antenna Patent Let's continue our discussion of the ferrite loopstick, a most interesting device. A curious animal appeared on the radio scene in March of 2003. It was called the Twin Coil Antenna. Its inventor was one Christopher Justice of the C. Crane Company. A July 2001 application for United States Patent number 6529169, "Twin Coil Antenna", shows an "antenna for a radio
- 10/09/2018 · This 7.5” loopstick D-808 construction article will guide you through the assembly of either a 7.5” Medium Wave loopstick D-808 or a 7.5” Longwave loopstick D-808, so make sure that you order the parts necessary for construction of your chosen model. The picture above shows the parts that will be necessary for construction of either model, but the Litz wire and 7.5” ferrite rod
- Hello, I am working on a 'just for fun' project where I am building a compact receiver for signals in the 10-200 kHz range and ideally would like to use a ferrite loopstick antenna, since these seem to offer good performance in a very small form factor.
- Long Loopstick Antenna Wound on a 3 foot length of PVC pipe, the long loopstick antenna was an experiment to try to improve AM radio reception without using a long wire or ground. It works fairly well and greatly improved reception of a weak station 130 miles away.
