Yes, the gutters are coupling with your loop. MOve the loop as far away from the gutters as possible.

Try winding about half that on the PVC. I think that your coils are too tight and there is a lot of coupling going on between the windings, which would increase the inductance and not be a good match for shortwave frequencies. . You didn't say how long the PVC was. Last time I did a helical vertical like that, I used a 20 foot long bamboo pole and wound plastic coated speaker wire on it and spaced the coils about 2" apart. Worked really well in the 49 meter international broadcast band.
