The Ferrite Snap On Combo Pack is a convenient solution for troubleshooting RFI/EMI with various diameter cables ranging from 1/4″ to 3/4″ for use as either single turn or multiple turn ferrite chokes. The snap on chokes are useful for RF coax, AC/DC power cables, and device interconnection cables.
Always use a snap on with a larger inside diameter than the diameter of the cable and use multiple turns if possible (2 turns through the snap on is the same as 4 snap ons with 1 turns). Included in these combo packs are our most popular snap on sizes as follows:
SABRE 50:100 (2:1) CUBE™ Balun (1.8-31 MHz), 2KW Top Studs Output
Product Details
SPECIAL ORDER SABRE 2:1 CUBE Balun™ – (1.8-30 MHz)
(Original product part # was 770013S - circa 1999)
Model SABRE-2-2000 is a 2:1 (100:50) quad core balun used to translate a 50 ohm input to 100 ohms at RF power levels up to 2000 watts PEP when used with a matched load. This assembled balun features a quad core configuration for increased power handling and flatter frequency response to 31 MHz. With a matched 100 ohm load the SWR over the frequency range 1.8 to 30 MHz is shown in the following table measured with an AIM 4170 network analyzer. Notice that the conversion from 100 to 50 ohms is very consistent from 1.8-31 Mhz and SWR is less than 1.5:1 over the range allowing easy tuning by most radio internal antenna tuners or an external tuner. Graph is for a 2:1 balun often used with delta loop, log periodic, horizontal loop antennas and HF Radar.
Input connector is 50 ohm type N (SO-239 also available - inquire).SABRE-2-2000 is in a NEMA 4x4x2 weatherproof box with mounting flanges at bottom to attach to fixed location (mast, wall, beam antenna, etc.).
Eye bolts and studs are all stainless steel for long life.
