    I test EME2-144 and it works excellent.
    I can hear beacon i didn’t hear before.
    This is really professional LNA amplifier

    The 12-element 2m antenna 2m12DX7 (PA144-12-7BGP) and EME2-144 are working brilliantly in the contests.

    I have received the EME2-144 Outdoor and Bias Tee.
    They are installed on the tower and working great!!
    Thank You for making a quality product available to the Amateur Community!!

    My EME2-432 preamp arrived on Friday, the day before an ARRL UHF contest, which was the first test of the 432 preamp. My 432 radio is an Icom IC-9700 and the sensitivity was greatly improved. I did a few tests with other stations running FT8 and in some cases could not decode the stations with the preamp in bypass mode but they had very strong signals with the preamp enabled. I also have the EME2-144 2meter preamp and have been completely satisfied with its performance.
