Hello de KJ4UO.

I have a SF-95 sate finder meter with range of 950 to 2150 MHz.  I'm wandering if anyone has check to see if these finder can detect the 900Mhz and higher amateur bands ?

I really need something for our 33cm 915MHz band.

These meters are so cheap, like $10 new, find them just about anywhere.  They would be so good for a ham related project.

Most (if not all) of these devices are in-line between a device called an LNB (low noise block downconverter) at the feedhorn and a satellite receiver. The LNB greatly amplifies the satellite signal in order to overcome coax losses and to allow for multiple receivers. They also depend on measuring the total power in the bandwidth of the LNB, often 500MHz or more.

They might be useful as a field strength meter if you were very close to a transmitting antenna, but that's about it.
