Although I prefer balanced feedlines for my homebrewed antennas, they sometimes prove difficult to install because of limitations imposed by your home's or apartment's structure. In this respect, coaxial cable feedlines have a definite advantage. In this video from KJ4KAF, we see how a little creativity can overcome some of installation challenges presented by balanced feedlines. Generally, balanced feedlines such as 450 ohm ladder line, 300 ohm television twin lead, and homemade 600 ohm feedline show lower losses than coaxial cables. Balanced feedlines, along with a sturdy antenna transmatch ("tuner") and a 4:1 current balun will allow multiband use from a single HF dipole antenna. Hopefully, this video will give some suggestions on how to use a balanced feedline in your shack.
