K9ay loop. Here are the instructions for constructing the loop itself.

K9ay loop. A 9:1 impedance-matching transformer is connected from one end of the loop to the ground and terminating resistor is connected the other end of the loop to the ground. . Here are all the details you need to build the K9AY Loop antenna system, including a relay-controlled pattern-switching system that uses the coaxial feed line to carry the switching system control voltage. The K9AY is terminated loop. It consists of a wire loop of any convenient shape (diamond, delta, etc), hung from a single support and with a ground rod at the bottom. Here are the instructions for constructing the loop itself. If you don’t want to make the loop using ‘homebrew’ construction, we also offer the AYL-M kit that includes a mast, wire and all the hardware needed to construct the antenna. Each loop provides reception from two directions when the feed point and termination are reversed, for a total of four separate patterns. (SM6LKM photo) The next figure shows the basic pattern plots for the K9AY Loop. Feb 9, 2018 · Thank you to Frank Sessink (PA0FSB) for submitting to us his document describing the K9AY loop antenna (pdf), which is the antenna that he successfully uses with his RTL-SDR for HF reception. The antenna combines magnetic (H) and electric (E) field reception in order to create a directive radiation pattern. The K9AY loop antenna for 160 and 80m bands You don't have the space to put up a 4 beverage antenna's, an EWE or a 4-square and want 'good ears' on 160 and 80m? No problems try a K9AY loop antenna ! This is a very performing receiving antenna for frequencies up to 4 Mhz, which exhibits an impressive F/B ratio, especially on MF. Frank extends the idea by showing a method that can adjust the directivity electrically The K9AY Loop at SM6LKM shows how one user implemented construction. The AY Technologies AYL-4 K9AY Loop Control system provides the electronic portion of the K9AY Loop receiving antenna system. Here are all the details you need to build the K9AY Loop antenna system, including a relay-controlled patternswitching system that uses the coaxial feed line to carry the switching system control voltage. Note that there is one deep null off the back, and at least 10 dB front-to-back is maintained over a modest vertical and horizontal angle. daw shnww vndl ruhayx rxdqlp qwtzq rogqgosx qrwki rowufy qjbgzcd
