Hello,
I'm getting ready for the next CQWW SSB contest and I'm working in phasing 2
1/4 wave verticals for 75 meters and all simulations shows that best gain is
obtained with 135 degrees phasing, but I would like to know how to obtain
135 degrees phasing with the length of the phasing lines; 90 degrees is easy
because it uses 1/4 wave electrical length for the phasing lines, which can
be calculated using the velocity factor of the lines used, but 135 is not as
easy.
I can obtain 90 degrees phasing using two 1/4 wave RG-11 and one 1/4 wave
RG-8 for the phasing that will be switched using 2 relays, but 135 degrees
is another story.
