What is the best and cheapest aerial for tv in motorhome

The best FM aerials are those that go on roofs. Your local TV aerial installer should also be able to supply and advise you on the best FM aerial.

It is not getting any signal. Look at........

- aerial cable connections. digital TV needs the best cable (quad shield) and the best connectors (F-type recommended). Then

- proper lock in of stations. Do another auto-search for detected stations

- is your aerial OK? Have birds roosted and bent it?

- if in an apartment block, check with other residents. The common aerial split system may have failed
.

Digital TV's need good aerials or you might finish up with some stations or none at all. Indoor aerials will only work if you live in an area that has strong signals from the transmitter. You can ask your neighbours if you need a proper aerial or not.
Ideally the above type of aerial is best.

cheapest way is a signal booster........
cheers

optimum reception of colour requires a good signal and will generally mean that an outdoor aerial must be used. the exact type and positioning of the aerial will depend upon your particular area your dealer or service personnel can best advise you on which aerial to use in your area. before connecting the aerial cable,turn off all main power switches. vhf or uhf it must first go to the media box and you will see the input aerial cable connect it there and the output go to the back of your tv that indicates aerial input terminal.

yes/buy a freeview box/cheapest way

If you have got a good aerial, the high gain type- see image, it should run all the TV's you say. Make certain you have decent cable coming off the aerial (the stuff they use for satalite dishes). Then buy some high quality splitters, to feed the TV's. Don't split the cable outdoors!

You may need a digital booster when sharing 1 aerial.
They are quite cheap (£5 on e-bay is the cheapest I've seen) and easy to fit.
Also the coaxial cable can make a differance, you really need shielded and with as few joints as possible.
I hope this helps.
P.S. try tuning with just the problem set connected to the aerial direct.

bodysnatcher ..make sure your unit has a good earth..do not rely on an earth from aerial..some times when units are installed.and there is bad earth connection it will earth through the aerial only .after a while your aerial may start to loose a good connection and unit is trying to sus an earth somewhere
