LNA 200 Preamp. 145 MHz N-female


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".
