Areas of major concern are the Gigabit Ethernet Cat5(e) and Cat6 cables used for network (LAN) connections between personal computers, printers, multi-port switches, cable modems, routers and radio transceivers, and between many other devices.ĭX Engineering ISO-PLUS RF filters, installed on both ends of Ethernet cables, work two ways. DX Engineering ISO-PLUS Ethernet RF Filters have no effect on throughput Ethernet data signal levels and speed remain unchanged.Įlectromagnetic interference (EMI), also known as RF interference (RFI), can be imposed onto your received radio and data signals from many electronic devices normally found around a residence, a radio room or a business network.
Their patented* design provides common mode RF interference and EMI noise filtering of radio frequencies from well below 1 MHz to 100 MHz and beyond.
“If you can’t hear them, you can’t work them.” Order ISO-PLUS Ethernet RF Filters exclusively from ĭX Engineering ISO-PLUS Ethernet RF FiltersĭX Engineering ISO-PLUS Ethernet RF Filters are very effective EMI Suppressors that are quickly and easily connected inline on Cat5e or Cat6 network cables. DX Engineering offers many useful accessories for the reduction of RFI in the station including DX Engineering Ferrite and the Radio RF Ground Plane KitsĭX Engineering ISO-PLUS Ethernet RF Filters are an important tool to improve productivity and radio reception of weak signals. Proper power and RF wiring and grounding, quality coaxial cable and connector installation, and tight positive mechanical connections are all very important, as well as other good RF practices. However, most wall adapters do not have proper filtering and can cause significant interference problems.īe aware that proper equipment installations will contribute to the reduction or elimination of RF and noise interference. Some switching power supplies that are specifically designed for use with Amateur radios usually have extra internal filtering to avoid causing RF interference in the amateur radio bands. Linear power supplies are usually better than switching power supplies. ISO-PLUS RF Filters can reduce or eliminate this trouble.Īlways use RF clean power supplies. Even if the RJ-45 cables are “shielded”, and especially if the shield is terminated at both ends of the cable, then the shield becomes just another conductor which can receive unwanted signals and reradiate them just as any other wire in the cable might do. Proximity of transmitting antennas near internal wiring can cause interference that gets into Ethernet cables. Once RFI is in the Ethernet cable it acts as an antenna and radiates RF signals that can be picked up by your receiver. The RFI generated internally by the device can be radiated over the Ethernet cable. RFI can creep in from switching power supplies, wall power adapters, dimmer switches, touch lamps, appliances and just about anything near Ethernet cables.
