If you are working at low frequencies, I have seen an idea using a very long
wire (say 4-5 wavelengths) at a low height above ground (say about 6 feet).
The antenna can be directive in it's long axis. It can help to reduce QRM
from a particular direction. Of course you need a fair bit of room...

Hey group,


I build a PI network antenna tuner with 2 variable caps and an air
form coil. Is there a componant I can add to this device to reduce
noise from my random wire? I have heard a 1-1 transformer may help.

I have a few toroids with very high Al (79uH per hundred turns)
kicking around. Can I wind one of these to use a noise reducer?

any other suggestions to reduce noise?

can someone toss me a link to a howto?

thanks,

mike
