2018-10-24 I've been playing with a two band trap inverted vee for some time now with good success. I very much like the band-switching simplicity, a convenience that for now is worth the decreased bandwidth compared with a regular inverted vee. I'm into the inverted vee arrangement rather than a dipole just because of the simplicity of putting it up, particularly in a portable situation but I think everything I'm learning is relevant for the dipole as well.
My next project is to build a multi-band trap antenna for 17, 20, 30 and 40 meters. I'm wondering how the added traps will impact the bandwidth of each band? If the impact is not too "bad" then the added convenience of band changing will be worth it. I may also add 17 meters to my Sotabeams linked inverted vee. Will make an interesting comparison as each segment of the linked version should perform pretty much like a stand along inverted vee for that band.
