We make a 20 amp, hard-wired filter, p/n AF300. It has a 40:1 blocking
ratio at 80kHz-150kHz. Since you mentioned a 30 loads in your post, it
may be a little more complicated. I would find if hard to believe that
you have all 30 receivers and load on a single 20 amp circuit. However,
it may be what you want. Many of the mail order places handle them, but
if you can't find them, call our office at 800-886-2281 (ask for PCC
sales) and they will tell you a local ESC who has them. Since we deal
mostly in commercial / industrial work, you can't get our stuff as
easily as Radio Shack. We sell mostly through independent companies
which we call "ESC's" (Engineered Systems Centers). There is probably
one near you.
