Topbanders,
thank you for the comments so far.
With the initial setup the feedline crossed the entire run in the air,
high enough to let even cars with antennas pass under it.
After i buried the feedline, the antenna had become so quiet that i
checked for loose connections at the feedpoint and the termination
resistor. Amazing.
The feedline is buried about 3-4 inches for the first 7-8 meters, then
about 1 inch for the rest (about 20m).
The transformer is a BN73-something binocular core, wound as suggested
by W0BTU and others.
Someone suggested to ground the feedline where it leaves the ground (at
the shack end), will this improve things?
