Product Details

Purpose. The CU-4-1500 is used as a 4:1 (200 ohm unbalanced load to 50 ohm unbalanced source) broadband transformer for 50 ohm coax cable rated at at 1500 PEP into 200 ohms unbalanced load from 1.8-61 MHz. Excellent for 43 foot verticals and also slopers (51', 85' or 119" work great)

USE: The top connector is for the 200 ohm unbalanced output, and the side connector is for a ground rod or radial connection.The SO-239 input connector shield/ground is shared with the ground connector.

For best results use a feed line choke between the CU-4-1500 and the coax input to isolate the coax from becoming part of the antenna. Our Maxi-Choker (MC-1-3000) is an excellent companion for this unun.
