Hi there,

You don't necessarily need anything else, but you may not have a strong enough signal to pick up the digital/freeview channels using an indoor aerial. It could also be that the indoor aerial is not correctly aligned.

If the signal strength is lower than approx. 50%, the TV may detect them during the automatic channel scan but it wont store them. When the signal strength for any digital channel is 50% or lower it's more or less unwatchable - the picture would be constantly breaking-up or freezing and the audio drops out continually. Trying to scan for channels using an indoor aerial is rather hit and miss. Numerous attempts may be necessary before you get any channels.

Assuming you have a roof aerial, it is far easier to temporarily connect the TV to a fixed aerial point while you run the automatic channel scan. The TV will store all the channels and you can then move it to it's permanent location and connect the indoor aerial. You can then adjust the indoor aerial with the channels already stored until you find a location for the aerial where you have a good signal.

Doing it this way also eliminates the possibility of a fault with the TV and confirms that you are performing the channel scan correctly. If the TV is connected to a fixed aerial point and you are still unable to receive or store any channels, then it's likely that you are performing the channel scan incorrectly or there is a fault with the TV.

Please try scanning your channels using a known working fixed aerial point. If you are still unable
to receive any channels - or you don't have any fixed aerial points - please post back for further assistance.

Hope this helps.

Regards,
BElectric

If i have a smart tv, do I need a booster for an outdoor antenna, I am planning on a 20-30ft pole, for the antenna


The benefit and functionality of a smart tv is derived as much from a good internet connection as from decent signal strength from the antenna.

The ideal height, type and direction of the antenna depends entirely on the signal strength available where you are and the length and type of downlead cable.

If the signal strength is poor it is generally better to use a high gain wideband aerial designed for fringe reception than to use a lower gain and a booster.
It is worth noting a booster can usefully help increase the strength of a weak but good quality signal but there is little advantage boosting a signal that is both weak and poor quality so it is best to obtain the best signal possible before considering a booster.

A low specification downlead can reduce the signal and gather interference causing a bad signal/noise ratio. Using a booster at the end of such a downlead will boost the interference as well as the signal - the best place for a booster is as close to the aerial as possible and masthead types are produced to avoid those types of problem.

It is best practice to use the highest quality downlead cable - double wrapped air spaced low-loss 75 ohm coaxial cable.

My signal strength is really bad on my TVs. Should I buy a new antenna?


The more tvs you have hooked up to the same antenna, the lower the signal strength. Therefore you should get an antenna amplifier or get a new antenna with a stronger signal.

Problems on the freeview 21inch Tv Teknica from Tesco was working when we bought it 2 years ago cannot get all the channels and poor reception re installed channels many many times but does not maintain...


Hi,
you may want to try changing the coaxial aerial cable that feeds the tv, these can go faulty. also if you are running a series of tvs off one aerial, you should be using an aerial booster, other wise you will get a signal drop (as displayed on your tv).
If these small things don't cure it, the set requires replaceing as the tuning card is knackered

Most of the channels breaking up despite auto retuning


could be one of a few things,
low signal strength, aerial out of line with transmitter.
bad coax connections losing signal strength.
coax broken inside, or old and not low loss.
Get the aerial checked for direction, half a degree out of line over a few miles and you will lose a lot of signal strength, as will old coax (aerial cable) and if you are using an unshielded coax you could be losing signal strength through the cable itself. Replace the connecters and try to use a straight run of cable instead of having joins in it as these joins, even if using connecters, will cause a weak signal. If yiu are running more than one tv off your aerial, invest in a booster.

I have a DMR-EZ25EB and sometime after the freeview retune last year I realised I had not retuned. I retuned as per the instructions (and have done so several times since) but I have lost all my freeview...


Hi,

This is not related to your aerial as you have good reception with your TV. Some receiving units (i.e your DVDr) need the channel memory to be cleared before the re-scan is done. Otherwise the scan gets corrupted.

To resolve this do the following;

1. Remove the aerial from the equipment and leave unplugged.
2. Go to the menu and select rescan or retune. It’ll take a few minutes, but when it’s done, it should say ‘'no channels found’.
3. Disconnect the equipment from the mains power supply and leave it un-plugged for 30secs.
4. Re-connect both the aerial and the mains power supply and switch the equipment back on.
5. Go to menu again and select rescan or retune. You should now have all the channels available to you.

I believe this should resolve the issue for you. If so please do take a moment to accept my solution otherwise it will not credit to my ledger.

Thanks for using FixYa.

How to use 2 way tv signal booster


On the booster there should be one input plug (probably labelled antenna, or AE) and two output plugs (probably labelled TV1 and TV2). The cable from your aerial should go into the input plug, then your tv should plug into the tv plug.
It's best to have a short a cable as possible from the aerial to the booster. Often the booster is fitted in the attic, with the TV cables running to the appropriate rooms. This prevents the booster from 'boosting' any signal noise.

Technika 19in f/s telly in bedroom cannot get any stations with a portable ariel - can I get a different aerial instead of having to rewire the house!


One solution is to buy an hight gain aerial and a UHF amplifier booster box..but if you dont even receive poor quality signals then i think you will be struggling without relocating aerial into the loft or outside on a wal or roof. or wiring to a main aerial input via a matched splitter

Snowy picture, no reception?


Hi, Your question "Do bigger TV's need an aerial booster or something?" - No, normally it should work straight out. Boosters are used for fringe location not bigger TV. Pls a questions and some ideas: 1. "TV worked fine the night before" was it hooked up to Cable or aerial? 2. If cable, it is necessary that you change the settings of the TV from cable to STD or Air or something like that. Normally this can be done via the remote, menu, setting, set-up; 3. If aerial, you would probably need the assistance of a qualified service personnel. Apparently something got loose inside the Philips TV, not a big problem because you can still receive (BBC 1) but not the other channels, possibly a loose wiring, a disconnected connector. 4. If you feel comfortable working on it yourself, unplug the tv and the aerial, open the back and poke around. Trace from the aerial jack, the lead wires used, the connector to the main circuitry. Wiggle the wires a bit for any loose connection. 5. If #4 is not to your liking or if you do not find anything or no significant improvement after closing it up and running it again, guess you're back to #3. Hope this gives you some idea. Lots of luck and kind regards from the Philippines.
