Ok so here is my question. I dont have the money to spend on a legit ka band radar unit at the moment, but it would be nice to be able to test ka sensitivity, range, etc. I have noticed that you can purchase a used ka band radar antenna for a dash mount unit on ebay fairly cheap sometimes. Would it be possible to buy one of these and power it up in order to transmit only or is there some huge reason this will not work that I am just not aware of? Any thoughts would be great, if it is just a dumb idea that would be good information as well lol.
