The CU-64-1000VLFN is a 64:1 quad core, Unun housed in a NEMA enclosure box (4″ x 4″ x 2″) with top coax connector output of 3200 ohms used to translate a 50 Ω unbalanced coax input to 3200 Ω unbalanced output at RF power levels up to 1000 watts PEP. With a matched 3200 ohm load the SWR over the frequency range 150 KHz to 3 MHz is less than 3:1 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 64:1 balun will have the proper label and frequency range.
