    Signal loss at high UHF frequencies

    Overall: 2.5 out of 5

    The newer CM-94444 (identified by round flat lugs on the 300 ohm wires and the nomenclature "Matching Transformer - China" does not have a linear response through the UHF band. I have used a field strength meter to compare it to other manufacturers' devices. At high VHF frequencies the CM-94444 has a loss equivalent to the others. At higher UHF frequencies (physical channel 50 is the highest in my area) the CM-94444 shows a loss of approximately 4 db. If you live in a fringe area where you will be squeezing every microvolt from your antenna, the CM-94444 may not be the best product for your needs.

    Great Value

    Overall: 4.5 out of 5

    I used this to connect an older sd antenna to a hd tuner. The product works great, installed easily without any issues.

    I would recommend this product if you have an existing antenna and need to connect an 74ohm coaxial cable.
