RG-400 Coax Jumper Cable with PL-259's on each end - 6 inch pigtail, Double Shield, High Power
Product Details

This cable is 50 ohm and short 6 inch pigtail double shielded with foil and braid and PL-259 connectors on each end. All the connections inside are soldered and the cable is made of copper conductors with coax having PVC jacket. RG400 is generally useful up to 5000 watts PEP at HF frequencies below 30 MHz. Greater power capability and frequency range than RG-8X, yet similar physical size.

Use for short jumper for Palomar Engineers Noise Filters like CMNF-500-50 or SWR meter, etc.


** Our Customers also used this RG400 Coax in longer sizes to make ham radio common mode chokes up to 5KW PEP

Mobile RFI kits work two ways: They suppress RFI from on board computers and other sensing/control devices in your vehicle that may cause your radio to be a VICTIM of RFI, and second they suppress RFI generated by your radio as a SOURCE which may affect your on board computers or other devices.  Mobile operations of HF radios (1-30 Mhz) tend to experience more RFI effects than VHF/UHF mobile stations.  If you have both HF and VHF installations in your vehicles, you may need both kits.

To address separate solutions we have developed two separate RFI kits: one for HF (1.8-300 MHz) mobile installations and another for VHF/UHF (30-1000 MHz) mobile installations.  Each kit uses the appropriate ferrite mix for the frequency range desired.
