Topband: 160m U shaped open loop

[vk3pa]

Has  anyone tryed a open loop U shaped rx antenna for TB
We have no where to put in a RX antenna "but" the house block has 3  
fence lines, 2 sides 160 ft long es the back fence 60ft wide.
my idea is to run a wire around the fence line es feed it in the  
center of the rear run.
how do I feed the center? its for rx on TB only!!
