I've used this on just about every antenna I've ever had. Helps you dial in low SWR for best transmitted signals. I've also used the frequency counter to align some old CB radios for a friend of mine. Comes with rechargeable batteries. Very versatile! $150 cash or PayPal - no trades please
I also have an MFJ-259 that works great. You'll have to supply the batteries. $100 cash or PayPal - no trades please
