I would suggest a fanned dipole configuration with elements cut for 80, 40 and 20 meters - feed it with the RG-213 directly (or through a balun if you have one).
Cut the elements for 40 and 20 plenty long (about 15%) and cut the 80 meter elements for the low part of the band (3.5 MHz). You will have to do a lot of cut and try to get it tuned - fan the elements for each band as far away from each other as possible to reduce interaction (maybe easiest to guy them in a circle 60 degrees apart around your center support), then start tuning on the lowest band and work upward. The theory is that the 80 meter wire will also serve on the 3rd harmonic at 30 meters and the 40 meter element will similarly serve on 15 as a 3/2 wavelength antenna, giving you coverage of 80 thru 15 meters with the 3 elements. The harmonic operation will only provide a low SWR if you cut the 80 and 40 meter sections for the low end of the band. The SWR may not be perfect on all bands, but then you have a tuner to compensate, so it will be tolerable with the RG-213. Try it and see - it would give you a good multiband antenna even without a tuner in many cases. 73, Don W3FPR > -----Original Message----- > > My only antenna currently here at the home QTH is an HF2V vertical > which does great for long haul DX on 40 and 80 but in general is not > good for local or regional work.
