text: Matching to an antenna using a cut segment of transmission line (described below) is perhaps the most efficient of all matching schemes in terms of electrical power, but typically can only cover a range about 3.5–3.7 MHz wide in the HF band – a very small range indeed, compared to the 27 MHz bandwidth of a well-made broadband balun.
