Works fine but a problem! Time Owned: more than 12 months.
Use this balun with Mosley TA32-Jr-N.
I chose this balun because the power I use is limited to 100 watts of transceiver and prefer it to the choke suggested by Mosley.
After a year of use, I had problems of swr.
After disassembling I saw that a weld was cold. I remaked all the welds and now works fine.
The advantage is that it is easily disassembled without breaking anything, the defect is that you should not disassemble for some sloppy welding in.
Anyway I have seen that after a very wet and rainy year inside there was no trace of moisture.
Note: BU-55 can be marked Diamond either Proxel ... Change the label but are the same!
