TV Aerials

I'm having problems on some sites in the uk for tv picture quality.I have  Round digital roof aerial but on site in Norfolk  other campers were using free standing tv dishes and getting good results.

What do I need to do this and any recommendations welcomw

just bought a satgear with easyfind lnb and will be giving a try next week in the lake district. will let you know how i got on later.

You will need a directional ariel -( the round ones are not very good) together with a booster that has a signal strength indicator. The new digital service does not give a blanket signal like the old analogue system and the masts give out a directional broadcast which can be checked on the internet. You would be surprised to find that some sites (being rural in nature) have signifcant gaps in coverage. Also usehul to have is an app providing aerial direction advice.

antenna aligner for iphones. good app.

As you have avtex tv with sat receiver fitted .May be previous owner was using external point to plug in sat cable by using the converter  jack plugs that come  with the m/home .to save fiddling With screw on type .in what can be a tight position . On external point .did this with my mates caravan made it much easier to connect up .

You will also need to know if the broadcast mast is horizontal or vertical polarised. Another reason why those omni directional or bee sting/stick aerials are less than useless in certain areas.

I haven't read all the previous posts,but on my Avtex television it has a facility to see the signal strength and quality information on a bar graphs.

On my remote control it is one of the 4 bottom buttons.This will give you some indication of the signal strength coming in.

Quick question though,are you actually setting the aerial up with a signal finder,these were readily available from places like Maplins but now on the internet.

If it is a Avtex DRS TV with a free to air sat receiver built in, just get a sat. dish solves any problem with the caravan aerial and always a good picture.

as long as there is nothing in the way like trees.

Never had a problem, have 25mtr of sat. cable so can move the dish to get a good line of sight.
