Dont loose me guys...
Sorry, but it really is not as simple of a question as it sounds. The radiation pattern is
three-dimensional, and will be different on each bad due to how the currents are
distributed on the wires. The three-dimensional nature means that, since contacts
over different distances require the antenna to radiate at different vertical angles
above ground, the directional properties will be different if the other station is 50,
500 or 2000 miles away.
40m is the simplest case: the antenna radiation pattern is similar to a dipole. In the
inverted vee configuration the overall pattern for shorter paths will be nearly
omnidirectional. At somewhat further distances it will be a bit better broadside to the
antenna. So the alignment isn't critical, but if you had a particular interest in working
New England or Alaska you could point it in that direction, but it might not make a lot
If the antenna was horizontal, maximum radiation on 20m will be at roughly 40 degrees
to the line of the wire, with nulls broadside to the wire. Sloping the wires changes it
somewhat, but also starts to fill in the broadside null. The signal in the direction of the
long wire is slightly stronger, but not by a lot, but there is still more signal off the ends
than broadside to the wire.
On 10m the pattern has 8 lobes. The relative strengths vary with the vertical angle, but
it is hard to say that any particular lobes are much stronger than the rest. You'll get
somewhat stronger signals in some directions and weaker ones in others, but not any
My thoughts are to place the angle of the legs at 120deg or close to it
Looking at the computer models, the best results are with the antenna as flat as possible.
I was also going to place them in a East to West direction so North and South is broadside, is this a good idea for the QTH of Southern Arizona?
That should cover most of the Western US on 40m, with some contacts further out.
On 20m, putting the long wire to the East might be the best choice, as it would cover much
of the Eastern US.
On 10m you'll have contacts in many directions, and I don't think it matters much which way
you point it.
