Hello!
I want to make a question.
We have installed several months ago beverages, one for USA, EU, JA and ZL. The
180 meters long are most of them. The transformer is the DXE, and the other 3
the W8JI. RG59 coax it shack and the feeding point about 15 to 20 meters. At
the point of feed use 1/2 ground rod and the termination of 400 to 600 ohms
resistance (depending on the F/B) that gave us the EZNec. The height of each
beverage varies from 2 to 2.5 m above ground.
The problem we have is that beverages make too much noise, and is not an
electrical noise, the question is to disconnect the ground that the noise
begins to fall.
It may be that the shield or ground make noise? the noise floor is from S5 to
S7 160m depending on the day.
As I can remove noise entering through the ground? and how to isolate the
shield?
Thank you!
