Things between your TV aerial and your transmitter will affect the amount of signal that you receive. This isn’t to say that you need to have line of sight with your transmitter because the way TV signals flow through the air is not unlike ripples in a pond when a stone is thrown in. But obstructions closer to the aerial side rather than the transmitter can hugely affect your TV signal and ruin your reception. Nearby buildings can block the signal, this usually happens when a large building has been built nearby which starts to block the signal because an existing TV aerial probably wouldn’t have been installed in a location where the signal was already being blocked and not working properly. This has happened with in my neck of the woods Eastbourne, where the transformation of our local shopping centre has started to block TV signals from nearby buildings. Trees are an aerial & satellite installer’s worst enemy. The main problems with trees are that they grow over time, move in the wind and leaf in the summer. All of these can give inconsistent reception and affect some frequencies & services and not others. I have installed aerials where the signal was pretty much perfect and a year down the line had to move the aerial because trees had grown and completely ruined the signal. It’s best to avoid trees altogether if possible but if there are only one of two then they usually won’t be a problem but where trees are dense they can become a pain in terms of reception. Temporary structures can also be a problem too, like scaffolds. Although these are usually far more of a problem with satellite dishes rather than TV aerials.
To fix, sometimes it’s easy to fix this problem other times it can be more difficult or even not possible. Some of the things that can be done to avoid nearby obstructions like buildings and trees running your aerial signal are, relocating your TV aerial to a new position where it’s not being affected, I have already mentioned a case where I had to move an aerial from a chimney to a side wall to avoid some nearby trees but often just moving antenna higher can help. Realign your TV aerial to a different transmitter. Or where neither of these works opt for satellite instead of a TV aerial, this doesn’t mean that you have to go and buy Sky because free satellite TV services like Freesat exist which is actually very similar to Freeview. With Trees of course you have the option of pruning the tree to a height which no longer blocks your TV signal. With temporary structures likes scaffolds, you could move your TV aerial onto the temporary structure until to get a good signal until after which when the scaffold is not longer required and then it can be 
re-fitted to its original location.

Because all TV’s makes, and models are different there is no definite hard and fast way to tell you how to get around this, especially if you don’t know your way around your TV or TV remote. But it is actually a very fast & easy fix.
9- Faulty Amplifier/ Distribution Equipment or Power Supply Unit
To fix, get a good quality piece of coaxial cable and make your own. You will also need a couple of coaxial plugs and a couple of hand tools. Fortunately, I have made a video on how to make your own high quality TV aerial fly-lead for you to watch, please also visit our Youtube channel for lots more videos like this. If you don’t fancy doing this then I recommend buying a good quality factory made lead. You don’t have to go bananas and spend ВЈ100 or $125 (whatever the current exchange rate is) on a gold or platinum lead. Just a lead that looks good quality and not the skinny type will normally suffice.
11- Poor Coaxial Cable Termination
To remove interference from 4G & 5G, modern aerials are designed to reject these frequencies, so an aerial upgrade might not be the worst idea in the world. You should also install a 4G or 5G filter to remove the unwanted interference. This should be installed before any amplification which may be in place so that the unwanted signals are not getting the benefit of extra amplification. It also means that where one aerial is serving multiple TV’s that, all the TV’s will receive the benefit of the filtering and you wouldn’t need separate filters at every TV. To remove interference from neighbouring transmitters bandpass filters which allow a small fraction of the frequency band through, but it really does depend on the transmitter you are using and the frequencies that you want to keep and to filter out so generic advice is difficult to give in this situation.
