Does the dipper dip on one of these frequencies in te absence of an
antenna?

???? The MFJ-259 is obviously infinity to one when you
have an open....

Is the receiver connected to the antenna, and can you move one of the
dips with the receiver tuning?

not using a receiver.

Does augmenting the antenna cable move one or both dips?

Didn't try this. Didn't have to change this
to fix the problem.

Does relocating the antenna change the dips?

Again, one of the two things i did to fix this
problem was to increase the height above the ground
from 3.5 feet to about 6.5 feet.

Can you guess what the other factor was?

Hint: no inductive choke was needed, and the radial
lengths remained the same.
