80m monoband dipole or G5RV for 80, 40m?
I have 140ft of solid copper wire and a length of 300 ohm twin lead feed line. I am primarily interested in the 80m and 40m bands for now and want to build a dipole that will suit my needs. I will probably use it for both CW and phone. I would like to gather some opinions on whether I should cut the wire for an 80m half wavelength or if I should follow the G5RV spec and cut the wire even shorter.
I have an MFJ-949e antenna tuner, so I have a decent range for tuning as well as the opportunity to bring in a balanced or unbalanced feed line.
I don't have any coax or an so-239 so I am planning on using the 300 ohm twin lead. Unfortunately, the twin lead is the cheap flimsy kind until I can get the heavier duty kind.
Let's assume the best configuration due to space will be an inverted V at probably 20ft apex (I know, that's low for a dipole). I don't know what kind of ground soil I have.
Let's pick the following frequencies (just a middle spot on the bands):
Will I be better off cutting for 80m monoband or going with the G5RV? Depending on which, what would be a ballpark length for the 80m inverted V monoband? (62'6")?
How about for the G5RV? (51')?
And feedline length? (32')?
I also have thought about trying out a fan dipole and just getting another length of wire, so perhaps both a 102ft wire and a 125ft wire....
