In this video from Peter Parker (VK3YE), we learn how to make this inexpensive, durable feed line from locally available materials. Here are some guidelines from Peter: "Open wire feedline is a cheap and low-loss feedline ideal for feeding HF dipoles. Open wire can tolerate significant impedence mismatches without adding much loss and in conjunction with a balanced antenna coupler allows multiband operation on a single dipole. Unlike a coax fed antenna the length of the dipole is not critical but for best efficiency aim for a minimum 3/8 wavelength at the lowest operation frequency (ie 30 metres for 3.5 MHz or the 80

Open wire feedline is cheap and low-loss, especially if you make it yourself.  In this video, Peter Parker (VK3YE) shows us a simple method of making your own balanced feed line for dipole antennas.  Balanced line feeders, used in conjunction with a balanced antenna "tuner" or "coupler", will allow your antenna system to tolerate significant impedance mismatches without adding much loss.  Balanced feed line used with a suitable antenna transmatch (i.e. "tuner") will permit multiband use on a single HF dipole.
