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

The Bullet-2-1-500EB (500 watts PEP) or the SBULLET-2-1-1500EB (1500 watts PEP) are both multi-core, 2:1 (50 ohm to 100 ohm) baluns plus a 1:1 feed line choke in a single compact (looks like a bullet) enclosure that is lightweight and easy to transport for your fixed/portable.

Very useful for single band horizontal or vertical loop antenna systems. Halyard hoist at top of balun for convenient attachment point. Input is via SO-239 UHF coax connector and output with side eye bolt output.

For multi-band loop antennas consider the Bullet-4-1-500EB or SBULLET-4-1-1500EB

Remember we over engineer our products, to out perform our competition - just compare the weight and frequency range of our baluns to theirs and you will know we put much more into our products so you don't have to worry about failure at a critical moment.
