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
Home Theater/Audiophile RFI Kit
The Home Theater RFI Kits are specifically designed to cure most home theater systems triggered by Radio Frequency Interference problems from AM, FM, CB and Ham radio stations. The kits contain ferrite toroids (“Ring” shaped) for the AC power cord protection and “Snap on” ferrite beads for HDMI, audio, video and speaker cables. The ferrites are selected to eliminate RFI from 1 to 1000 MHz. The ferrites are easy to install, don’t require modification of the protected equipment and work in almost all cases to suppress annoying interference issues.
