What is the best way to tune a fan dipole in the attic? I built my first "test" 20m dipole and put it in the front room of my house (I have high vaulted ceilings). For some unknown reason my wife wants me to build a more permanent solution in the attic very soon (HOA rules) so that I can remove the lovely decoration and center piece of her friends discussion. It took some work to tune the dipole using a loaner swr/power meter and that was with great access to both legs. What is the best way to tune in an attic where I will have to walk across my joists and other features (vaulted ceilings)? Will I get close enough if I tune outside where I have space to work prior to putting in my attic? Should I use an antenna analyzer rather than the SWR/power meter? I can get a loaner analyzer if needed.
Also, I don't have enough space for an 80m inverted V on my home diagonal, but I do if I go with one leg along the back edge and the other leg along the side edge ( think inverted V if looking from the sky). Should I do my 80-40-20-12-10 dipole all this way or just the 80m and the rest as an inverted V on the diagonal?
Thanks for the help.
