I bought this meter in May of last year but I have another meter so I don't need it. It is in great condition and comes with connectors for PL259's to connect to it. It reads SWR and wattage and is very accurate. It would be perfect for trouble shooting mobile antennas as well as base antennas. You could even take it up the tower and use it while you tune your antenna. Save your self trips up and down the tower with this meter. No owners manual but it is very simple to use. Just plug it up and press the button on the front and get your SWR then press again and get a forward wattage reading.
