Freeview aerial comparison

[Rodders53]

Which is where a sat dish excels..

Until the boat rocks (or is a very expensive sat-following motorised job).
Or especially if there are trees between the boat and satellite, or even canal-side and it if placed on the land by the mooring.
Tricky enough finding a pitch with a clear view on a caravan site sometimes.

I've read that a loft aerial can expect a 30% reduction in signal strength compare to an outside mount.

You have mis-read that: -10dB Voltage = multiply by 0.316.
So you get 31% of the signal cf outside = a 69% reduction.

If you have clear line of sight to make it work. Of course, if you do, then happy days. Satellite carries far more HD versions of the channel mix for a start. Caravanners love them. I find that boaty people are less enthused. They say it mostly comes down to storage space.

So many now use their mobile phone and just stream what they want to watch. An aerial on a mast can be stowed when not in use, so it's an acceptable backup. Cheaper, too, which seems to be important for some. Your mileage may vary, as they say.

Only for a few more years.

Gone in 3.

You would sit the dish, on the ground, which doesn't (usually) rock.
