I guess Sea Dog's problems breakdown into two issues.
- the faff setting up the dish
- what to use as a tuner/recorder.
I've been using satellite this year and gone down the Sky Q route 'cause I like watching footy and rugby. For setting up the dish, I find my sat finder is great...and if there is a good line of sight to the satellite, i can set it up in a couple of minutes. Sky Q uses a 'funny' lnb so I had to get a normal 60cm dish which is mounted on a vertical stub. Dead easy to rotate etc. The only issue I have is that when using a compass to try and get the bearing, the metal of the boat skews the compass bearing. Usually I get the approx direction from looking at the map of the canal and then tuning via the sat finder and ignoring the compass. The faff comes if there are any trees in the way and the signal is marginal or non existant and then it can be a real faff. The trick is parking the boat where it wont be a faff...no trees...which in this recent weather is a problem. Once I have a signal, it is very stable as the dish seems to give fairly broad coverage if the boat rocks or rotates.
For the tuner, sky Q is a compromise. Great recording potential but you cant watch recorded problems if switched off and no signal on booting up. You therefore need to leave it on in standby when no dish in place. That takes a lot of power .....I think around 3A.....and the box gets hot. That's 36Ahrs if its on 24/7. eeeek. So you either park under trees in the cool and listen to music or park in the sun with loads of power and watch the footy.
We do also have a tv aerial so can get digital freeview if no Sky.
