Product Details

The CU-16-1500VLFN is a 16:1 quad core, Unun housed in a NEMA enclosure box (4″ x 4″ x 2″) with top coax connector output of 800 ohms used to translate a 50 Ω unbalanced coax input to 800 Ω unbalanced output at RF power levels up to 1000 watts PEP. With a matched 800 ohm load the SWR over the frequency range 150 KHz to 5 MHz is less than 2:1 on the coax input.

The GROUND terminal is connected to the 50 Ω INPUT connector shield.

Input and output connectors are type "N".

Also includes ground lug/wingnut connected to input and output shield connectors.

Note: Picture shows unun with 9:! ratio which is shown for illustration of the form factor. Actual 16:1 balun will have the proper label and frequency range.

16:1 Baluns are useful between 750-850 ohm balanced loads where the impedance at the  end of the feed line is 800 ohms (1/2 wavelength feed line), or high impedance feeds for rhombic,  T2FD and traveling wave antennas.

16:1 Ununs are useful between coax and long wires with a load impedance near 800 ohms like a beverage antenna.  Shortwave listener antennas also can benefit with the 16:1 unun and it may provide a better match than 9:1 ununs – this means quieter noise levels and stronger signals so you can hear distance stations easier.
