I am going to do my 1st attempt at phasing verticals. I have 2 Butternut HF2V verticals. I would like to have the phasing work on both bands. If I have them 66 feet apart can I phase them 1/4 wave on 80 meters and 1/2 wave on 40 meters. I know that it would be better phasing them on only one band. But could I do it without distorting the radiation patterns to bad. Get a good SWR in the phone DX windows and do without a tuner? Or if not, can it be setup for 80 and using tuner get good results on 40? I have done reading in ARRL Antenna Book, Low-Band DXing and Internet sights. But really could not find an answer.
Tnx and 73 Mike K4MIA
If you want them to have essentially the same end-fire pattern on both bands, they have to be spaced about 35 feet apart and you have to use a 90-135 degree delay on 40 and a 135-145 degree delay on 80.
You could use cross-fire phasing and use one delay line for both bands, but antenna impedances are an issue.
