RF Systems "MLB" {Magnetic Longwire Balun} - What Is It ?snip
I've got one, not that I use it anymore. It seems to be the only balun
with low frequency specs. I did MW reception with it, but I never
compared it to the ham baluns.

- Get a Wellbrook.

M-Sushi - Is that like Get-A-Life ! ) ~ RHF

FWIW - The Wellbrook "Universal Magnetic Balun" [ UMB ]
is a Receiving Antenna Balun with a 9:1 impedance ratio.

Note - Universal Magnetic Balun [UMB] is specifically designed
to Reduce Noise, especially mains borne, by isolating the feeder
winding of the Balun [Matching Transformer} from the Antenna.

How does it distinguish between noise and station signals?

Pretty smart balun.

- Much of the noise you encounter is generated in your own house.

-R- That is true.

- Any balun allows you to run coax near these noise generators,
- which is better than just running the bare wire antenna by them.

-R- OK - But why not move the Balun and Wire Antenna
Element out-and-away from the house and the noise.

Again a key-point that Wellbrook makes is the Five Metre (5m)
{which is about 16 Feet} "Noise Zone" that exists around a
House and getting the Wire Antenna Element away {out} from
this area. = http://www.wellbrook.uk.com/longwire.html
