This is a generic linear amplifier RFI kit for DC powered amplifiers. Works on many popular amplifiers including:
Specially designed for the Elecraft KPA500 linear amplifier used with the KX3 and similar transceivers.
Included are the following chokes and installation guidelines:
Included are the following chokes and installation guidelines:
RF Input:F240 ring – 5-9 turns of RG-58 size through center
RF Output:FSB-1 (Big Clamp on) – 3 turns of RG-8 size cable
PA KEY Cable:FSB-1/2 – multiple turns through choke – ½” diameter hole
AC Power Line:F240 ring – 5-6 turns through center
Computer/RS232/AUX Cable:FSB-1/2 – multiple turns through choke – ½” diameter hole
Also make sure you connect a good RF ground to the amplifier ground post.
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!!!!!
