Can anyone suggest a way to improve our TV reception? very tall trees next door cause the problem?

Do you have a line of sight to the satellite from anywhere in your garden? You can locate it there and run a cable to your house........

Cant you speak to your neighbours and tell them their trees are causing a problem?

We live in a neighborhood with tall trees as well and the only way we can "fix" it is by buying cable or the like, television.

An obvious choice would be to mount your aerial on a large pole.

I had same problembut now have two indoor boosters and the reception is fine

First tought that came to my mind is cable.

Put your antenna on top of the tallest tree that is the cheapest solution in case the trees are taller than your antenna pole.

Get a freeview box it should boost the signal enough for you to get a picture

Higher gain antenna, higher antenna, check the condition of your lead in cables and whether a balun should be fitted at the antenna or near the set. Ensure the antenna is suitable for the bands the TV stations are in. An old VHF antenna is not much good for UHF and vice versa. Check the polarisation of the transmitters. Some TV stations transmit a vertically polarised signal and a horizontal antenna at the receiver will not receive much of that signal even if it's on the right band. Phone the stations if you can't find out any other way. They have an interest in getting you to watch. All this is true whether the signal is analog or digital. The trees should not block too much of the terrestrial signal if its on UHF and less on VHF. If its microwave you could have trouble.
