Description

Fully assembled, tested, and installed in a metal enclosure with female
BNC connectors on input and output.
Based on the MAR7 device, this receive only preamplifier (no transmit
switching) covers 100 MHz to 500 MHz.  
This includes the137 MHz WX, 2M, and 70cm satellite bands.  
Operates from +9-15V DC (a fresh 9V battery works great!).

Ready to operate–not a kit!  Includes low power (about 5W)
protection diode on the input for accidental transmissions into the
input.

Perfect for portable operations using a dual band hand-held Yagi like
the ARROW, Cheap Yagi, etc.  
Just put it inline on the correct receive band for operations in either
mode U/V or V/U.  You won’t believe what you’ve been missing!
