I don't use a TV when caravanning John. But have been dispatched onto a roof of an RV more than once to get the satellite dish set up and I haven't a clue.
The compass on a lanyard acts as plumb bob for the post and then a shout for the compass settings and you are as near as dam it on the right set up, often the meter is not even needed and in far from ideal positions!
A stressed out race team boss or race driver is 10 times worse than a good lady wanting to watch her favourite prog I can assure you.
They want what they pay for working, or the guys are down the road! Forget Swiss Tony, the guys mostly work on tight budgets so expensive equipment is a non starter they have to turn up and have the media systems working pronto.
John,
I never use a compass to find the satellite, I do however, use a dash mounted compass to select my pitch on-site.
I drive around the site until I find a pitch that will give line of site to 151.2 degrees.
Lining up to Astra is not difficult nor magic and the Televes is very accurate. Just mount your dish on a tripod or your jockey wheel or where-ever. Connect the sat.finder to the LNB and the output of the satfinder to you digibox and turn the box on.
You should now hear the audio from the Televes, if you wish you can now switch the Televes to meter only.
Rotate the dish further East than you will need it, turn the gain up on the Televes and turn the dish clockwise until the meter deflects. Reduce the gain so that the meter needle is about half way, then rock the dish slowly from left to right to obtain maximum deflection and lock the dish.
For the vertical setting, flex the dish from the bottom and then the top whilst standing behind or to the side of the dish.
This flexing will deflect the Televes needle and indicate which way to move the dish, up or down if at all. It isn't rocket science. The above may sound complex but once you have done it once you will find it a simple 5 minute job.
Just ensure that you have line of sight to the satellite (no trees etc).
