OFF CENTER FED DIPOLE NOTES Here are some typical OCF dipoles that are successful designs 160-6 meter Double Off Center Fed antenna layout (using a double tuned stub for better 20/40 meter performance) Here is the 160-6 meter SWR graph using 200 feet of RG213 feed line and an average COAX FEED LINE COMMON MODE CHOKES (1:1) Coax Common Mode Chokes Common Mode Current (CMC) carried on the outside of a coaxial cable braid from your antenna can cause unwanted RF in your radio shack and can radiate this unwanted RF into you and your neighbor’s electronic devices. These currents can burn your fingers on the key or lips on your microphone FERRITE MIX SELECTION BOAT OWNER’S ELECTRONIC INTERFERENCE SUPPRESSION KIT Boat Owner’s Electronic Interference Suppression Kit. Use this filter kit to suppress interference noise between electronic devices on your boat including: radar, fish finders, audio/video systems, inverter noise, solar controllers, vhf radio, marine/ham radio, auto pilots, electronic gauges, PA systems, and many other electronic

devices.

SOLAR SYSTEM RFI

The Problem As solar photovoltaic (pv) system installations are becoming more popular, solar pv radio frequency interference (RFI) is also becoming more evident and effective RFI suppression techniques are needed to ensure the performance of electronic devices connected to or in the presence of the pv system.

FERRITE CORE PRODUCTS Ferrite Rings, Beads & Snap Ons. Ferrite Flat Cable RFI/Noise Filter, 1.35" wide slot RFI Range 10-500 MHz, 1 Piece QRP BALUNS/UNUNS (1:1-16:1) 1:1 MINI-BALUN/Line Isolator, 50 Ohm input, 50 ohm Balanced Output 500 Watts PEP, 1-61 MHz, Ladder Line Interface to coax, Flagpole Antenna LIGHT DIMMER SWITCH RFI/EMI SOLUTIONS Light dimmer Switches are often a significant SOURCE contributor to electrical interference to surrounding electronic VICTIMS connected to the same AC power line. When the dimmers are turned off, the interference goes away, but when active interference becomes a major problem. Many times the use of dimmers is mandatory, such as in a commercial establishment HAM RADIO/SWL ANTENNA APPLICATION NOTES BULLET END FED … Revised11/18/2020 Bullet 148 Inverted L (vertical 25’, horizontal 123’, Bullet-9U (2 feet above ground) – 100 Feet coax, choke at 64 feet from antenna feed point only – two 15’ counterpoises wires. MIX 31 | SLIP ON FERRITE BEADS Application Note: Use impedances for each bead at your desired frequency to select number of beads needed for desired Z. For example if you have a 50 ohm RG-8 coax cable and want a choking impedance of 500 ohms at 10 Mhz, you can check the FB102 column (since FB102 will pass RG-8 through its center ID) at 10Mhz and find that Mix 31 has a Z of 108 ohms/bead and Mix 43 has a Z of 91 ohms/bead.
