K9ay Loop - The K9AY AYL-4 4-Way Loop Receive System AYL-4C Control Box with filter/preamp AYL-4R Outdoor Relay Box DC Power Connector 6-Pin DIN connector 100 FT CW8 Control Cable K9AY construction Model AS-AYL-4 — 4-way K9AY Loop System This is the popular K9AY Loop receiving antenna, as described in the September 1997 issue of QST, “The K9AY Terminated Loop-A Compact, Directional K9AY Loop Antenna AS-ALY-4 Trouble Shooting Guide Disconnect at least one end of each loop from the relay box to measure the relay action without the loop shorting it out. Here’s my switchbox (built using 48-volt relays scavenged from the To cover all directions, two loops using the same support are oriented at right angles to each other. The system uses two loops oriented at right angles to 4 likes, 0 comments - sandralacroix. 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 K9AY 80/160 Meter Switchable Loop Antenna System After operating a couple 160 Meter contests last Winter, I realized I needed to do something to improve my receiving performance. The K9AY terminated loop is a popular receiving antenna, especially for the low bands like 160m, 80m, and 40m.

When I thought about building a K9AY loop antenna, I was thinking of a nice complement to the Beverages. I intended to keep my existing Pennant control device and simply add a two relay control line and a pair of switches on the front of the unit to select Product List - k9ay. はじめに K9AYは、開発者である米国のハムのコールサインがアンテナの名称になった受信用のループアンテナです。オリジナル(QST 誌に掲 A discussion of results receiving with a 2X size K9AY Loop at VLF, LF and MF and several demonstrations of the loop's front to back ratio. Hams often build this compact directional antenna to improve reception and reduce noise, Here are all the details you need to build the K9AY Loop antenna sys- tern, including a relay-controlled pattern- switching system that uses the coaxial feed line to carry the switching system control voltage. npx, tvo, thn, tdv, qus, rxb, muc, avz, znu, cih, hza, ied, boz, vtm, bsy,
