Many older cars/trucks have a fuel pump in the gas/diesel tank that emits RFI through the external gauge connections. The simplest solution is multiple ferrite beads on the fuel pump connection wires outside of the fuel pump. You may need to lift the car/truck to gain access to these wires. Use two FSB31-1/2 snap on beads on each wire (usually 2 or 3 wires depending on make/model). Works on boat fuel pumps also.
Due to many requests for antenna static bleeders, we have developed a product line of static bleeders for coax and for ladder line applications. Static electricity is caused by many situations including high desert wind, atmospheric conditions, etc. You may hear static crashes or have a buildup of static electricity that my be annoying during a radio conversation and it may be harmful to solid state electronics if high voltages are present on the RF input to your equipment.
A static “Bleeder” which shorts the direct static voltage to ground while leaving the RF frequency voltage unaffected if very beneficial particularly to those operations in desert conditions where low humidity, high static buildup are quite common. The SB-1 and SB-2 coax static bleeders work on coax line and the SB-3 static bleeder is meant for ladder line.
THESE DEVICES ARE NOT FOR LIGHTNING PROTECTION AND PROVIDES NO PROTECTION FOR LIGHTNING STRIKES!!!!!
