"Don’t waste your time or money on the cheap buzzer things."
Given a little aptitude, awareness and patience the audio satellite finders are anything but "a waste of money", they indeed save 90% of the investment in the more sophisticated units like the Primesat 500 and its clones.
The latter identifies the correct satellite has been found, rather than the audio units that typically respond to any signal.
However, this is where “awareness” comes into play, the satellite cluster we need for our UK TV is fortuitously located at the most Easterly side of the band of satellites likely to be found. Thus, if we set the dish at the correct elevation and move from a bearing of 140 degrees to the south, the first scream will be from the "right satellite". It just needs the said “aptitude” and “patience” to do this in a disciplined manner.
For those with the popular Avtex TV there is a further helping hand for setting the dish up. That TV range features an “Easy Find” licensed decoder. If used with a matched Easy Find configured LNB you have a “red amber green” LED on the LNB that displays green if targetting onto the “right satellite”. Therefore you can benefit from a cheap satellite finder sounding as you approach the satellite and the comfort of the flashing amber then green LED confirming you are on the correct target. No need to be told what is showing on the TV, all done where you stand setting the dish.

That said, you need the aptitude to do things systematically, then setting up is very straight forward, lack that gift and as we see so often people make a real tasks of doing it.
Edit: The inclusion of a signal attenuator into the aerial feed of the satellite finder, desensitises it, making it an even more precise unit. I use a 6db unit but up to a 10db should work as least as well. Remove it along with the finder after the job is done.
Whilst ordering from cpc including some of these "push on" "F" connectors make for less hassle than fiddling with the screw on type, in our portable application and particularly putting in and taking out the finder.
