[TowerTalk] 160m. Inverted L

[op155342c at mail.telepac.pt]

Just replaced my 160m. Inverted L old 2.5 mm wire with a 6mm flexible wire
(total length 38.9 meters, Vertical component 14.5 meters)and spite the antenna
seems to be transmitting ok with SWR below 1:1.8 from 1810 to 1870 I started
having a S7 noise (that I wipe out using the radio's NB filter), this noise
wasn't definitelly there with the old 2.5mm wire.

The noise resembles a motobyke noise when working at low RPM and I can't figure
out why Iam catching it now just after I replaced the antenna conductor.

If some of you got a previous experience with this type of antenna any help to
help get rider of this noise would be mostly apreciated.
