Hi to all,
An effective approach to multi-band operations is use a link antenna coupler combined with home brew ladder line and a balanced antenna, one antenna for many bands.
This antenna system allows you to series feed and parallel feed (current feed and voltage feed) your antenna.
If needed, this antenna system also allows you to add shunt or series reactance to your feed line (inductive/coil - or capacitive/ variable capacitor) to change effectively your antenna system electrical length.
Altering your antenna system electrical length provides a desired low impedance or high impedance point at the coupler feed line connection.
No folded back wire is needed. String up a random length balanced antenna and get on all the bands. This is a resonant antenna system.
Another words, once you have your link antenna system up and running you change bands by changing a couple of taps on the coil(s) and twist a couple of knobs to preset know positions. Done.
I have to agree. Put up as much wire as you can and use the tuner and / or feed line length for multiband use. Also be aware a folded back portion will act as a trap to any freq where it's a 1/4 WL.
