Build an end-fed half-wave antenna
WebAs a result, the feed line becomes an unintentional part of the antenna system, resulting in all of the aforementioned problems. In the case of an end-fed antenna fed with open-line, only one wire at the end of the feed line is connected to the half wave antenna. The other wire of the transmission line therefore is unconnected. WebIt is simply a half wave end-fed on 80m which will resonate on all multiples of that frequency, loaded with a small inductance near the feed end. This inductance has the effect of bring the resonances a bit lower, particularly …

It is not a good choice for working lower bands from a too short wire, that is, if you have cut your wire to a 20m halfwave, it ain't much punkin' for 40m, 80m, or 160m. It will be good for 15m, and 10m.
