Product Details
Brand: Palomar Engineers
UPC: Does not apply
MPN: SB-1
Type: NEW
Country/Region of Manufacture: United States

Model SB-3 is a static bleeder meant for ladder line use. It is rated from 1-60 Mhz at 3 KW with a maximum SWR of 10:1 on the line. The SB-3 bleeder is used in line with an existing ladder line fed antenna usually at the entrance to the radio shack, and on the “antenna side” of the antenna tuner.

Either ladder line connector can be used for input/output (bi-directional) and a ground should be connected to the Ground Lug. Under normal static conditions, the SB-3 will bleed off residual static. For very high static voltage it is recommended that the ladder line be grounded directly.

TUBE feed line chokes/Line Isolators are used to suppress common mode current carried on the outside of the  coax braid which is often responsible for receiver noise and RFI in the receiver/transmitter. These chokes are very useful for suppressing RFI common mode current at the antenna feed point, at 1/4 wavelength intervals along the coax feed line and also at the entrance to the radio station.  They are available with various input and output connectors so as to conveniently connect to standard output connectors already installed on your feed line.

Palomar Engineers TUBE feed line chokes are designed to have 2-5 times more choking impedance over a broader frequency range than competitor units in similar packaging.  Each choke has the choking impedance and effective frequency range on the product label so you can choose the product best suited for your application.
