T.V. displays 'No signal'.......?

Here is an interesting site which explains the significant deficiencies of the omni type aerials and recommends alternatives which work far better in both weak and strong signal areas.

I appreciate all the comments and feel better informed now but I'll leave it until we can try again when the 'van is in different locations. TBH I'm beginning to feel that being able to watch T.V. isn't worth the faffing around and I'd be better off just getting a couple of jigsaw puzzles (and an extra couple of bottles of St Emilion)!

We have a Moonraker DTV Digi PRO portable and an Avtex fitted in the 'van. Neither can get a signal on our current site.
The owner says he cant understand why - there are 2 masts to choose from and everyone else on site has no probs.
We have tried every option inc. changing cables and connecting direct to the TV. We also have 2 TVs and neither can get a signal.
On a site with TV hookup we have no probs.
Is it just that both TV aerials are rubbish or are we missing something?

I have come to this post rather late,and could I suggest plugging in a signal strength meter into the aerial socket in the van and see what indication this gives you.
Maplins or any good caravan shop sells them.
I always set up aerial first with the finder then set up the television.

Unfortunately today there are still areas across the country, many in those beautiful 'remote' areas caravaners enjoy visiting, which have a weak signal. The principals of gain and polarity blight omnis in these areas and better options are available.

But only in strong signal areas, anything less and you probably will need a directional one! That's why there have been problem occurring with those new caravans with omni aerials fitted in certain areas of the country. As the 'researcher' says, 'a metal coat hanger' may be better than the omnis!

Just look up to the roofs down every street in every town. How many houses have omni aerials fitted, none possibly I'd bet. Why? The answer is that they are inferior compared to directional ones and ill suited to many locations. Beggars belief that the manufacturers still fit them to caravans in my opinion.

Out of interest, here is our list, from the past 12 months, of sites where our omni was not good enough and we had to use either our satellite dish or TV on the bollard :-
Twyllite private site Banbury, CC&C Moffat, CC Strathclyde, CC Maragowan, CC Brora, CC Stonehaven, CC Yellowcraig, CC Dunnet Bay, CC York, CC Buxton, CC&C Keswick, CC Grassington, CC Bury, CC Barnard Castle, CC Broadway, CC&C Corfe Castle ... I would hardly class this number as very few... quite the reverse, there a very few in our experience, where it DOES work ..

A big factor in houses not having omni direction whereas caravans can have must be most houses don't relocate their position?
I have no argument though with not liking any omni I have yet come across, even very expensive marine ones. I much prefer directional types that can inherently have some level of "gain", before any amplification electronics come into play.

And that's where the rotational and polarity changeable directional aerials out perform the omni types, They provide the flexibility required in order to 'find' that optimal signal. We've been on sites in rural areas which have the possibility of tuning to either the main transmitter or a more local repeater. That's one circumstance when the directional ones can come into their own!

We find we have to retune the telly wherever we go , just find menu/auto tune set it off and wait , usually 5mins , you may have to move ariel about for best results but a quick look at your neighbours on the park will show you which way to point it.

I use Antenna Aligner which has been spot on every time and it's free👍😋
