Hi Misko and all.

Its very odd size...

No one known to me Windom's have that pair of size,
27 meters - is the one leg of ~42m total Windom for bands from 80m and up to 10m.

Maybe someone cut it too much trying to tune in band when installed too low
from the ground?

Windom for bands 40...10m usually have total length of ~21m. Its another antenna.

Just mean for half-wave dipole you need 1:1 balun or direct connection of coax
and ferrite-choke on it.
Most of Windom's have typical balun of 1:4 or 1:6, not suitable for classic center feed dipole.
