The devil is in the details – but if I had to have a very simple product brochure that explained what the u.RAT is, this would be it. I would say you can use any analog antenna tuner that you like – in the shack or remote out at the antenna. I’d say that the Palstar BT1500A is my tuner of choice for non coax (open wire fed) antennas. And while my tuner only has two knobs, three knob tuners and even tuners with switched inductors can be used. Its a perfect way to breath life into that old antenna tuner that’s just laying around – or, the antenna tuner you wanted to home brew yourself.
