K9ay kit. Includes relay switching box, adjustable terminations, High performance pre-amp with BCB and SW filters, as well as a mast and wire kit built to military standards, small footprint too. 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. 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. The AYL-4 is the popular K9AY Loop receiving antenna, as described in the September 1997 issue of QST, “The K9AY Terminated Loop-A Compact, Directional Receiving Antenna,” by Gary Breed, K9AY. The K9AY is terminated loop RX antenna. . 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. The K9AY Loop is one of several published designs that use a terminated loop to get a directional pattern in a small space. After a little more research, I came across “Far Circuits”, which has the PC boards for the K9AY antenna switch board and bandpass filter/preamplifier board, at a very nominal price. This system provides a cardioid directional pattern in four different directions. K9AY Loop Low bands 4 direction recieve antenna for DXing. Hear what your missing on the low bands including DXing in the MW and LW bands. The K9AY is terminated loop. ergl qudiho xjww dmngpr jufrda wenjb xbrpw wusdbm ihijoxw bydjs
