SWR and Feedline
The 25FM antenna has an input impedance of 200 ohms. The supplied balun matches the input to 50 ohms. If you are using transmission line with a characteristic impedance other than 50 ohms or 200 ohms, a matching device must be made. Refer to any current Amateur Handbook for information on constructing a matching device.
