LNA 200 Preamp. 145 MHz N-male

Product.Nr.: 1011-NM

product description

The new low-noise amplifier for the 2m band represents a completely new development of SSB-Electronic.
It replaces the LNA-145.

In addition to minimal self-noise and stable adjustment, great emphasis was placed on lowest oscillating behavior. The preamplifiers are mechanically very robust and offer excellent sensitivity at the same time.
New: Choose between the standard N Female connector / N connector (for direct sheeting on the relay etc) and SMA and order the appropriate variant.

The amplifiers are built into a rugged tinplate housing, suitable exclusively for indoor applications (IP41 according to EN 60529). The new amplifiers are labelled as "NEW".

The names have been adjusted too. We now consistently use the words of the band in cm, except for amplifiers for specific frequencies. Thus, for example the old "LNA145", an amplifier for the 2 m band (145MHz), is now called "LNA 200".
