testing an lnb

[billhiggs]

is there an easy way to test whether an lnb is working or not??
I picked up an old school rca dish w8ith the second lnb attached with one of the skewed metal brackets, and wanted to test if the lnbs are working before trying to do the aim

thanks

You can test the switch by removing it from the system and bringing it inside, using a 9 volt battery and a DVM, you
connect the battery positive to the switch output using a small piece of center conductor; the battery negative is
connected to the metal case of the switch.

Using the DVM you can test the 4 input ports of the switch by using another piece of center conductor; each port
should be about .8 to 1.2 volts less than the battery voltage (measure it first) any port less than 1.5 volts then the
battery voltage is a bad port.

Example:

Battery = 9.2 volts DC, port 1 = 8.2 volts, port 2 = 8.23 volts, port 3 = 8.15 volts, port 4 = 8.24 volts, this is a good switch.

Battery = 9.2 volts DC, port 1 = 8.2 volts, port 2 = 6.23 volts, port 3 = 8.15 volts, port 4 = 8.24 volts, this is a bad switch.
