New SNAP-AROUND Chokes

These can be closed and opened several times without damage.

They have a separate flap for attachment with a tie wrap or tape. So you do not have to tape around the large choke then the coax.  One or two turns, of tape, over the flap and around the coax and you are done.

 

 

Small Choke

This fits over RG58 and 8X easily and will slide on those size cables for easy placement after closing.   They have a separate flap for attachment with a tie wrap or tape. So you do not have to tape around the large choke then the coax.  One or two turns, of tape, over the flap and around the coax and you are done.

Although not recommended for this size coax, Personally I use these on my 9913  jumpers in my shack. It stretches to snap around and will not move.  If these are put on an RG8 sized cable that will move they will damage the cable or fall off.  

PRICE IS $2.00 each or $18/10

Small choke Dimensions: 

ID= .382 (.98cm) 

OD= .909 (2.33cm) 

Length = .495 (1.27cm)

LARGE choke

This fits around any of the commonly used cables and will slide for easy placement.  I also use them for headphone and power supply cable chokes.  Several turns (wraps) of the wires can be made prior to closing.  It shortens the cords to the needed length and works as a RF block at the same time. If you need to lengthen the cables later, you can open the choke unwrap a few turns and close it again.

    I personally use these on my headphone cables, I no longer get the hash in my ears while transmitting with my amp.  As well any AC or DC power cord I need to shorten and all my moving larger coax cables.   If it is outside these go on it because it is going to flex and move with the sun and wind. On small or large coax it fits and attaches to the rear of a standard PL259 connector, shown in photo below.

PRICE IS $2.50 each or $23/10
