[RFI] High noise level....

[Paul Walsh]

Hello All,
              I wonder if you could help me out with the following problem i have got...

Since putting up my new antenna (2 ele quad) i have got a very high noise level on 20m. Wether the antenna is at 25ft or 50ft it is just as strong at anywere between S5 and S7. This is worst when beaming to the West. The noise is worst on 20m, but it still is there on all other bands (10-20m) but the noise blanker on my ft847 gets rid of it on those bands except 20m.
I wonder if there is any filters or something i can make or purchase to get rid of the noise. As you can imagine this amount of noise drives me crazy when trying to work anything from the west. Or is it something i will have to put up with??

thanks in advance
Paul
