TV issue

[AlyJay]

Things being new is no guarantee they are good.
You say you tried in the house and it worked but not in the MH? did you use the same aerial cable in house and MH?
Has the TV got a way to show you the signal quality and strength? For example, an Avtex has an S/Q button to show what is being provided.
You say issues with new TV? did you have an TV in it previously? and did it work ok?
Is it a Directional aerial and if so is it pointing in the right way and orientation (V or H)? could it be pointing to a different transmitter to the aeriel on the house?
Is the TV 12V AND 240V? have you tried both and not just 240V in house and 12V in MH?
Have you another TV you could take into the MH and try?

I don't know if any of the above is of use to you but these are the troubleshooting steps I would be taking.

The TV is 12 v so when in house it was mains but through 12 v transformer.
I've tried 2 new aerial cables in moho , however they are F type connectors and not same as simple push in fits that are used in house so cables are not like for like.
House TVs are a mains 230v and not 12v as moho.
Moho had no TV before as it was missing.
I've been fannying around with it in vertical position today and I do get a very weak signal when I'm physically near aerial, the aerial does look to be pointing in correct position and the signal indicator is green.
I realise new stuff doesn't always work but generally these day you would have to be very unlucky or buy very cheap for it not to, so I'm going to move location of van when it goes bk on road and retry before I start condeming aerial/booster and see what happens.
What your saying makes perfect sense but I've checked as much as I'm able to and scratching my head
TV does have signal strength indicator and its not even weak as its not registered a signal most of time, I'm starting also to wonder if there's such a thing as TV - aerial compatibility? The TV is recommended for moho / caravan use as its 12V but like you say never take anything for granted

I was about to suggest the same And try the booster in the house to see what happens.

Yeah Ive bypassed it but it doesn't make any difference, cant test it in house as its 12v. Where I stay its middle of nowhere so I'll wait and move van when its taxed nearer town and try to re tune.

I have had green light on my booster and not been able to get any channels, but when we have moved to a different area all channels working fine

No differance whatsoever, ther has to be a fault with either the antenna and cables or the booster, easy test is bring a small desktop antenna and a new bit of cable out to the van, put the small antenna out through a skylight pointing to transmitter and see how that goes.

Post back when you discover what the problem was
I remember fairly soon after I got my Motorhome I couldn't get a TV signal. Spent ages messing around with the aerial position and in the end I think it was someone who asks if I turned on the booster? never had a booster before so didn't occur to me to check often the silliest things!

I dont have any other aerials to use.
Like I say I'm just going to move van when I put it bk on road probably in end of April.
I've done everything I possibly can and cant condem the main components until I try maybe in a more open space.
I totally agree with your logic but even in my house we are so rural we need aerial booster to recieve DTV.

I will do. I'm hoping its just van in crappy location, which could be very possible.
Thankyou for all your input.

This is what I'm wanting to hear, hopefully our van problem is the same. Cheers .

 

[Scotia]

Is the booster 12v or 240v ?

 

[trevskoda]

They are all 12v

 

[TJBi]

Does the booster have a Min/Max dial? Have you tried adjusting that?

Just one other comment .... It used to be a right pain getting the aerial aligned for a signal when I got my Motorhome (and remembered to turn on the booster ) and I decided after a year or so to upgrade the booster with the Status PLUS booster model that had the LED that changed colour as the signal improved.
It was an improvement on the old booster for sure but I was a bit disappointed that the it showed green when there was only a bit of a hint of a signal rather than being a progressive indicator from no/poor to good. I use it as more of a 'ballpark' indicator then anything else. I think you have the same booster by the sound of it?

I've done everything I possibly can and cant condem the main components until I try maybe in a more open space.

I remember one meetup in Kelso where a couple couldn't get any signal from their Satellite setup. Sods law that they happened to park in such a place where a lone tree a hundred foot or so away was in direct line of sight between their dish and the Astra satellite just had to repark and problem gone IIRC. In my van, I can't use the Sat system where I usually park, but if I move it to the other side of the driveway, it is ok.

even in my house we are so rural we need aerial booster to recieve DTV.

Same for me. I got a Sky system as DTV is just too poor to be reliable. Weirdly though, the TV setup in the Motorhome with the directional Aerial works a lot better then the house when at home. Odd.

 

[AlyJay]

Yes, had it high/low gain.

I'm leaning more towards the indicator being false hope as you say, it's lighting up green but signal is still crap.
It's the vision plus VP5 so possibly same one you mention.

Just checked ... I bought the VP4 back in September 2021 - exactly a year after I bought the Motorhome.
Looking at the pictures, not sure if the VP4 is older tech or is the same booster as VP5 but with less outputs (no radio and only two TV outlets)? Can't remember what the gain is set to - I never really fiddle around with it.
Overall I find that plus the directional aerial (same as yours looking at the mast there in the photo) overall pretty good.

As an aside, there are a couple of good phone apps you can get to help you get started on what general direction to aim it at and if it needs to be horizonal or vertical. Might be worth looking at if you haven't already? If there are other MHs or houses around, I tend to just look where their aerials are pointing and start off the same

 

[Wightman]

however they are F type connectors and not same as simple push in fits that are used in house so cables are not like for like.

So are you saying both ends of cable have f plugs and not normal push in coax type at tv end? If that's the case you are plugging into satellite socket as no TV I know of uses f plug for terrestrial reception. What make of TV is it? If it has coax plug at TV end can you not get mains and another TV on extension leads near enough to try your aerial setup with different TV at least it'll prove your aerial is working
Sorry if I've misread your post
Good look and let us know how you resolve it

Aerial booster is F type and also the inside of plug in connection is F type, then the outside of plug in connection is normal push fit as is TV.
I've bypassed the whole lot from booster to TV with a new normal cable with a F type cross over for booster.
Ive also tried direct from aerial to TV using the crossovers supplied for fault finding in the aerial kit.
I've tried 2 sets of cables.
The house cables are fixed aerial side which is on roof so I'm not going to be trying them in van.
I've 3 TVs in house, all large and all mounted to walls so cant be bothered removing them.
I'm 99% sure its a reception issue anyway from what others with same system are saying, the green light sometimes isn't a help.

 

[Wightman]

It does seem very strange with everything being new, didn't think that type of aerial would work straight into TV as thought electronics within that box powered the aerial signal. I've got very similar/same unit and only once have had to reply on our sat dish and we've got some pretty awful blackspot reception area's where we live/camp
If your signal strength meter on your TV isn't registering a signal in the van does it when you take TV indoors?

 

[merl]

I'm starting also to wonder if there's such a thing as TV - aerial compatibility?

Fortunately there's no such thing.
Does the TV have it's own signal strength meter/indicator? If so what does it say?
I'm in a rural fringe area and the LED on my unit barely changes from red to a sort of reddy orange, if you're getting full green in a poor signal area then I'm wondering if it's because you're actually picking up and amplifying a strong NON TV signal. Maybe the new amp is simply faulty.

 

[CriftinsCampers]

@AlyJay
I fitted a vision plus to my first van, never again absolutely appalling product, exactly the same problem as you described it would give the impression there was signal but often absolutely nothing unless in a really strong signal area with good line of sight

I also messed about horizontal vertical pointing it 180 out etc.

On both my current vans I now use the truly incredible Necvox magnetic antenna, if there’s signal out there these will pick something up where the vision plus would not.

I also have a fire stick however for 100% reliable tv I carry a portable satellite dish in the vans as backup, for when there’s no mobile or terrestrial tv signal often there’s not even radio 4 in large parts of the UK!

 

[Tezza33]

Is the Vision Plus aerial pointing the same way as the house aerial when you get the green light?
If you are in an area between two masts with different frequencies it is possible that you are pointing at the wrong one, if that is the case the TV would need retuning, if it is pointing the same way then it could be just a weak signal as already mentioned, unlike the old analogue system where you still got a fuzzy picture with a weak signal digital TV's are either on or nothing
