5:1 Baluns/Ununs

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:

CU 5 1500 antenna - 5:1 Baluns/Ununs

Also available as a balanced output – CB-5-1500

Product Details
MPN: RFI-INVERTER
Type: NEW
Country/Region of Manufacture: United States
Filter Power Rating (PEP watts): n/a
RFI Suppression Range (MHz): 150 KHz - 10 MHz
Typical Use:: DC-AC switch mode inverters common mode noise suppression

The RFI-INVERTER is a common mode noise filter set which filters both the DC input and AC output of DC-AC inverters. These filters effectively isolate the DC power cord and AC output cable from acting as antennas for the internal switching power supply. The filters suppress RFI from 150 KHz to 10 MHz. Simple to install on cables without any device modification. DC filter is a ring and AC output filter is a snap on with 1" inside diameter hole.

For larger cables use the ACCF-3 and DCCF-3 ring filters with 3" inside diameters and use multiple turns on each cable for best results.

AC power strip shown in picture NOT INCLUDED - this is user supplied and shown for illustration of filter installation.
