RG-400 Coax Jumper Cable with PL-259's on each end - 3 feet, Double Shield, High PowerProduct DetailsThis cable is 50 ohm and 3 feet long 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 use with Simple Dipole Feed line Choke (SDFLC) to make a 10 turn high wattage feed line choke. Also useful between radio devices such as transceiver and amplifier, antenna tuner, SWR meter, etc.
** Our Customers also used this RG400 Coax to make ham radio common mode chokes up to 5KW PEP

Christmas lights or yard lights with switching DC power supplies are often the RFI source and a clamp on ferrite bead on the AC AND the DC side feeding the lights is needed to help suppress the switching power supply RFI noise. Suitable snap on beads are FSB31-1/2 for the 1-250 MHz range.
We have also had reported wireless HDTV boxes, and FOSCAM and AMCREST security camera systems causing RFI to garage door remote openers. Use our Garage Door Opener RFI kit to suppress the interference to the opener (VICTIM) – you need one kit for each opener. Maximize the distance from the camera to the openers may also help. Additionally shield cable to the garage door sensors may be needed depending on severity of the camera RFI.
Obvious Tech Note: make sure your remote batteries have enough energy to activate the GDO or the signal they transmit may not be large enough to over ride the RFI signal, but a fresh battery may be able to overcome the weak RFI source and allow the GDO to operate correctly.
