    This 4:1 unun toroid was NOT attached to the mounting tape. Also, the TOROID was TOUCHING both coax CONTACTS wires and was rattling around. The Toroid was not even pushed to the back. The wires wrapping the toroid were loose. This is the second problem I have had with LDG in a row. It seems their quality control seems non egsistant as of late. I have heard of many others having problems. If you do buy, be sure to OPEN THE BOX and do your own QUALITY CHECK!!!

    4:1 low power UNUN

    I don't run over 100 watts on this unit so works well. I did seal it better for outdoor use.
