cheap 433 module - antenna please? Is this a waste of time?

Paul_KD7HB: I just realized I could actually use a piece of equipment to tune into a frequency and HEAR what is going on. Does a newbie/entry level radio receiver allow me to tune up to 5.8 ghz to hear those signals too? Do they come with strength meters ?

The quick answer is no. An entry level receiver probably stops at about 30MHz. The 433 MHz is part of the band of frequencies from 430-470 MHz that is shared between amateur radio, government radar, and the 433 part that is used by all the various devices sending telemetry data, including industrial devices running low power. Government has first priority, then amateurs, then all the rest.

There is an amateur radio band from 5650-5925, so some equipment may be available, but is usually separate converters that allow part of that band to be translated down to a lower frequency receiver.

pretty rare that you can find any regular commercial receivers for that high a frequency.
