Hom(e)brew open wire feeder

If you can't see the video, please insert this title URL into your browser search box:  https://www.youtube.com/watch?v=-d3g957EaQ8.  This post 2181 in a continuing series of simple ham radio antennas.

Thanks to George Donaldson (EI7KO) for this simple, inexpensive method of making open wire feeders for HF antennas.  The main problem with do it yourself (DIY) balanced feed lines is getting a sufficient number of wire spreaders for the feed line.  George has come up with some good ideas in this regard.

Balanced feeders are great for feeding loop and dipole antennas.  With a balanced "tuner", it's possible for a HF dipole to cover several Amateur/Ham Radio bands.

For another interesting open wire feeder design, please check out the March 2020 "QST", pp. 30-33.  Robert J. Zavrel, Jr. (W7SX) shows you another method of making open wire line for your antenna.
