I have a single K9AY broadside NE/SW that I use with a palomar 108 Pre-amp on my table. It is is the best RX antenna I have ever used. I took down my AB0X shielded loop and stopped using snakes. Wish I had gone ahead and put up another with all the switching circuit but it does reasonably well on South America. I use it on 160 and 80. 73 Dave K4JRB
