Broadband VHF/UHF/WX Satellite RX Preamp

  • Here are the internal components and the case.  Note that unlike some preamps this unit is NOT RF switched.  It MUST be protected from inadvertent transmitted RF. 






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!

Full details and schematic can be found in the November/December 2012 AMSAT Journal article by Mark Spencer, WA8SME, or downloaded here:
