5:1 CUBE™ Unun – Model CU-5-1500 (50:250 Ohm, 1.8-61 MHz, 1.5KW PEP)
Application. For traveling wave, end fed or portable 20-31 foot vertical antennas the 5:1 unun makes a good transformer for converting 50 ohm coax to a 250 ohm feed point. If you use the antenna on multiple bands, the feed point impedance may not always be 250 ohms and use of the unun at high (>350 ohms) or low (<100 ohms) will require reduced power input or the unun may have its power ratings exceeded and damage to the unun may occur. The (5:1 conversion ratio will change for loads other than 250 ohms unbalanced.
Typical application:
Also available as a balanced output – CB-5-1500
Smart Appliance RFI Kit - Washer, Dryer, Microwave, Refrigerator, Vacuum Cleaner, Clock or Lamp - 6 filtersProduct DetailsMPN: RFI-HTS-SWType: NEWCountry/Region of Manufacture: USAFilter Power Rating (PEP watts): not applicableRFI Suppression Range (MHz): 1-300 MHzThis RFI kit is specifically designed to suppress interference triggered by today's smart appliances used in the kitchen and household that act as "transmitters" and affect other appliances or radio/TV/Cable audio systems OR these appliances may act as "receiver" of energy from other devices such as ham radio, CB, AM broadcast and other electronic devices in the home. The problem is generally the AC power cable acting as an "antenna" picking up or transmitting signals.
The RFI kit has ferrite filters are selected to eliminate RFI from 1 to 300 MHz and are typically used on the AC power lie of your Washer, Dryer, Microwave, Refrigerator and AC powered Clocks and Lamps. The filters are easy to install, don’t require modification of the protected equipment and work in almost all cases.
What is included in the kit?
The RFI kit contains 3 ring filters (1.4" ID), 1 large snap on (1" ID) and 2 smaller (1/2" ID) snap on filters for clock or lamps. Installation examples are shown in the included manual. Simple, easy to install and effective in almost all conditions.
