The CU-49-2000LF is a 49 Unun housed in a NEMA enclosure box (4″ x 4″ x 2″) with top coax connector output of 2450 ohms used to translate a 50 Ω unbalanced coax input to 2450 Ω unbalanced output at RF power levels up to 2000 watts PEP. With a matched 2450 ohm load the SWR over the frequency range 1-10 MHz is less than 2:1 on the coax input terminal.

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

Input connector is a SO-239.

Also includes ground lug/wingnut connected to input shield connector.

This unun is DC grounded.
