[TowerTalk] [RFI] where to buy FairRite?

[Dennis Vernacchia]

*Kostas,

You can try going to Mouser Electronics for the clamp on type by going to
www.mouser.com   and entering manufacturer's number in search window as I
know they carry several 31 mix
( and other Mixes ) clamp on type ( see info below )

Otherwise here is more info I hope will help you

*see below info and maybe pass on to others
( Info is couple years old so prices have surely increased since then )



  I was in the process of making a group buy for our local radio club
of some -31 Mix Ferrite clamp on beads
that will fit tightly on RG-213 size coax and also be good for smaller
cables that I could
thread thru several times for efficacy. ( Hole is approx 0.400" )

    I discovered that Mouser Electronics now sells at least this one
particular -31 Mix Ferrite
bead that works well for RFI problems per Jim Brown's recommendations in the
past
on this reflector. ( These do well in place of 43 or 77 mix and I now use
this
mix from 160 thru 6 mtr band to resolve RFI probs with good results )

    They are $2.70 in small quantity but drop to $1.70 for 100 pieces, so
get together with
a few buddies or your local contest or DX club and snap up the discount !

You can get to Mouser's order page by typing

0431167281

in Google search and it will be the first hit you get

or go to www.mouser.com and enter part number  623-0431167281

NOTE: Important !
I found one anomaly with these and that is that if you do use them to snap
directly onto
RG-213 type coax ( approx 0.400" Diameter) or coax with the same diameter,
the plastic shell that comes
with the bead has a slightly smaller diameter than the hole in the ferrite
bead itself and will not allow
you to clamp the bead onto the coax until you take a pair of diagonal
cutters and trim the
plastic making the hole bigger. Just a nuisance for now as I have alerted
Mouser  and Fair-rite
and hopefully they will use the correct plastic shell in the future.

2.4 inch Donuts

    If you would like to buy 2.4" Round ( Donut ) type, ( Fair-Rite
P/N 2631803802
)
and these are really great for really tough RFI problems, you can order them
from Dexter Magnetic Technologies
     I am not sure what their minimum order is but when I do my group buys
of 100 pieces
I have gotten a piece cost down near $3, though I hear the price will be
rising sharply soon
due to the price of one of the materials use in making the -31 MIX - ( like
going to $4.28 ea in 100 Qty ! )
