has anyone actually used one of these, and if so can they verify that it's better (in the sense of lower losses) than the channel master baluns ?
it would be for use with a CM4228
to partially answer my own question, I came across Tin Lee's web page a couple of years ago and got a quote (so the prices are out of date).
I was looking for a balun for a CM4228, which gets high vhf as well as uhf.
Maybe I've misunderstood their quote, but they offered to sell me a "MT-37X 0089",
and at the end of the quote, it seems that this is simply a channel master balun ???
