DIY Field strength meter !

darkm4n · 5th January 2004, 08:54 PM

Hi ,

I need help again .. maybe i'll found it here ...
I need a scheme / howto for a FSM that can help me setup satellite antenna's .. so .. with a large freq. range ..

I need that for positioning mobile antenna's ( TV use ) on satellite's .. to see on the FSM in what position the signal is the best .
Thank's !

These Sattelite Finders (and similar types) are easily available from Sat-TV suppliers are are not expensive.

I can't find that device in romania ...
I need a simple scheme ... but it'a another problem .. the LNB need a power supply to work .. the satellite recevier give about 12 V to the LNB .

Search on google for 'field strength meter' and you should find a few schematics, some good, some bad. Most of them are for HAM use so they are tuned to some AM frequency bands like 80 MHz to 100 MHz. Some of them go a little higher. If you're doing sattelite, you'll probably be wanting a little higher frequency so you might have to tweak your own design.

I need to build a FSM myself for a project but it needs to detect from 400 Hz to 24 MHz. Here are two sites I think were useful.

Hmm ...

I don't need only a higher freq .. i need a power supply included in to it ... to power the LNB of the antenna ...
