These antennas represent a radical departure from previous attempts to design a horizontally polarized omnidirectional antenna. I recently saw that my 80m (3. GRA-1899T Muti-Band HF VHF (80m-6m) 3. This makes transportation easier. 03 twinlead Quarterwave Vertical is: 4. The 6m band is his most popular one, since he get best results on this band. The goals of the project were to provide an optimized antenna for 40m, 80m, 20m, and all other HF ham bands, in that order of priority.
