Topband: [Bulk] Re: Elimination of Treadmill RFI on 160 meters

[Grant Saviers]

Pretty hard to find a box with the volume you need and already cut for 
outlets.  What I do for large size line filters is use a plastic 
junction box from Home Depot (Carlon or Thomas & Betts).  They come 
4x4x2, 4x4x4, 6x6x4 and larger.  Then a pigtail out to a standard outlet 
box of any type you desire and in with a power cord with plug.  Use 
rubber grip cable or Kellems strain reliefs on both cords from HD or 
McMaster or Grainger.
