INTRODUCTION
Thank you for choosing KA1 as one of your antennas. We are sure KA1 will make your DXing
more competitive as well as enjoyable.
You can adjust elements length by the controller in your shack which means you can adjust not
only SWR but also F/B ratio and gain of the antenna.
Please read this manual carefully to understand how KA1 works and how to use it.
KA1 is much heavier than ordinary Yagi antenna that has the same number of elements. It also has
some sharp parts which may hurt you if you touch them roughly. Please be careful when you
construct it or do maintenance
.
CAUTION
*Do not use AC adaptor or cable that doesn’t come with KA1.
*Before installing KA1 on the tower, please make and confirm Adjustable Element Unit (AEU)
working on the ground.
*Pull off the DC plug from the controller when you attach or remove the Amphenol connector.
*While in operation (elements are not fully out or home, in between), push HOME button to get all
the elements home position if you pull off the DC plug. Otherwise KA1 may lose the accurate
position. This should happen when you experience black out.
＊Please use the only parts(bolt, nut, washer, etc.,) that are supplied with
KA1 or the same ones as supplied to assemble KA1.
