I have the a wand type tv ariel but find I don’t get good signal, is there anything I can do to boost signal or would I be better fitting a different one

    In a strong signal area it should be okay, as would a coat hanger, but anything less and you will need a directional aerial and better still, a directional one which allows you to change from horizontal to vertical polarity.

    I have used an Avtex aerial for some years.https://www.avtex.co.uk/antenna/sth3000

    It has a built in amplifier that is powered down the co-axial cable if you are also using an Avtex TV. They cost about £35/40.

    Before visiting a site I look up the local transmitters https://ukfree.tv/maps/freeview

    When I get to site I attach the aerial to the side of the van or a window with the suction mount, pointing it in the direction of my chosen transmitter. I then press auto-tune on the TV and carry on setting up the van.

    To date it has not let me down. If a signal is available it will find it.

    I’ve heard good reports about the Avtex, eM Is it interchangeable between horizontal and vertical horizontal polarity? Looking at your info. page on transmitters it appears not to list relay transmitters, just the main ones. As we often visit remote sites in somewhat challenging locations as far as transmitted signals are concerned this info. would be very helpful. It’s not just if a signal is available, sometimes it’s the quality, orientation and strength of that signal that makes all the difference.

    You've got me there micky. I am aware that with the fin type aerials you can rotate them so you can pick up a signal from either transmitters or the relay type that feed off them, but I have always used my Avtex in a vertical manner, as shown in the web pictures.

    There is an application titled "Freepoint" that is specifically for caravanners as it lists the bearing from every site in UK to the nearby transmitters. It give the number of channels available on each as well as the H/V required and the distance.  Only difficulty - and it is outwith the control of the application - is that trees grow taller and degrade the signal strength.

    As far as I’m aware a relay mast is usually the opposite polarisation to the main mast. I’m told that this is to limit any interference from it and other mast transmissions (slight lags) an area could be on the fringes of. Well that’s my understanding but it’s best to match the polarisation for best results in poorer signal areas.

    I use the 'Antenna Aligner' App on my phone which lists all the transmitters in your area - in descending order of signal strength and also shows whether or not it requires Horizontal or Vertical alignment.

    I have never seen a house anywhere with an omni directional aerial on its roof. I’ve never seen a house without an aerial correctly aligned for polarity.  That’s says it all. The video explains all you need to know to get the best possible reception in most areas including those challenging ones.
