Model SB-1 is a static bleeder meant for 50 or 75 ohm coax line. It is rated from 1-150 Mhz at 1.5KW with a maximum SWR of 5:1 on the line. The bleeder is used on a coax “T” in line with the coax transmission line as shown in the picture below.
SB-1 Coax Static Bleeder installed on coax “T” connector
To use procure a coax “T” and a male to male connector. Connect the SB-1 to the male to male connector and thence to the coax “T”. Static voltages are bled off from the center conductor to the outside conductor (braid of the coax). At the entrance to your radio station ensure that the outside conductor of the coax transmission line is grounded so as to provide a sink for the static electricity on the antenna center conductor.
The SB-1 static bleeder is usually installed near the radio shack entrance on the antenna side of any 1:1 baluns/line isolators (between isolator and radio) if used.
the connector is a male PL-259 and will fit into a SO-239 (female) or "T" with female counterpart to the PL-259. Small, convenient, effective and easy to install! "T" connector shown in picture NOT included.
We specify impedance ratios as an output to input ratio where the output (or load) is given first and the input is given second (e.g. 100:50 (2:1) would mean a 100 ohm output and a 50 ohm input; a 25:50 (1:2) would mean a 25 ohm load and a 50 ohm input). Most all products use a 50 ohm input unless otherwise specified.
We have products that are available as kits for the do-it-yourself (DIY) person or fully assembled and tested units for the “Plug & Play” crowd.
Our impedance transformers are available using two different topologies: Binocular cores or toroid cores with multiple turns for increased effectiveness and wide band frequency transformations. We utilize single and multiple core transformers using high order windings when needed to extend product performance.
We rate the power ratings as watts PEP (Peak Envelop Power) with standard duty cycles for various modes. To determine the PEP rating required for your needs, see: Choke & Transformer Power Ratings
