Do you have to add a converter box to receive free

Will just an HD antenna work or do you need the converter box to receive signal over the air? This is a temporary fix as lightning hit our cable pole.

You will need a converter box or a separate tuner. The TV has an NTSC (analog) tuner.

I hope this helps.

(the $40 boxes that are available are mostly SD. You should check the specs if you want a HD tuner.)

Is the Ematic AT103B Converter Box compatible with Suddenlink cable/digital service?


No, the Ematic AT103B is an over-the-air digital ATSC tuner and will also can convert the digital signal to analog NTSC for older TV tuners. It will not work with any cable service and is for "cord-cutters". The AT103B requires an antenna to receive your local OTA channels. Depending on where you live, you may get some channels with an indoor antenna. You will get better reception with an outdoor antenna. See http://www.tvfool.com or http://www.antennaweb.org for details on the channels you can receive with an antenna pointed in a particular direction.

The Ematic set top box does provide an HD signal output and a DVR (time-shift function) so it is more advanced than the first generation OTA converter boxes. The original (available with the government coupon) converter boxes only gave an SD output.

I hope this helps.

(antennaweb.org gives a very conservative list of available channels but assumes an external antenna. tvfool.com lists the channels that are likely to be received with a variety of antenna strengths. An antenna signal amplifier can improve the reception. (Digital stations will not be seen if the tuner can't lock onto the signal.) However, when the amplifier fails, you may find some channels will not be received at all.)

How to tune samsung tv


Mono is the first point I am stuck on. Mono is an audio reference but I am going to assume that you are only receiving the analog channels and not the digital. If you are coming off of an antenna then the antenna has to be HD to receive HD channels over the air. If you are off of a cable box then this has to be dealt with from your provider. You will also need an HD ready TV or if you do not you will need an HD converter box to make your tv work with the digital signal.

How do I get the free digital channels on my tv?


One way you can get free high quality digital channels is an HD antenna. In recent years, the government stopped broadcasting analog (non-HD) signals, and instead pumped out HD. They advertised their "converter box", that made it possible for people receiving their TV channels from antenna, to get HD.
If you currently have an antenna that you prefer to use, you can buy a converter box here.
But, the solution that in the end will get you more channels is a new HD antenna. They range from extremely powerful roof antenna's, to average tabletop antenna's. A roof antenna has more distance, but can be more hard to set up compared to the tabletop ones.
You can buy a variety of tabletop ones Here
Or, you can choose outdoor Here
You can learn to set it up Here
If your TV doesn't have HD capabilities ("HDTV") than you will need a converter box, which can buy at the link above ( or here.).
Hope this helped!

Since the switch to digital transmission, my antenna no longer works with my Trutech 19 inch TV. What kind of antenna do I need to buy in order to get reception?


to add to what MIKEY-MOORE wrote, OUR government was offering discount ($20 off a $40-$45) coupons on a digital converter box that you can use your original antenna ( I still use my original nineteen and 65 (1965) rabbit ears antenna) to receive the digital signals NOW being transmitted through the air. In order to receive the signals YOU MUST get the converter. GOTO any Radio Shack, Walmart, to acquire the converter box. You will need one for EVERY tv in your house. I have a HDTV (but not digital) and I had to buy 3 boxes.

Hdtv converter box to vcr


Hi Drtrippy,

If I understand correctly, you are using your VCR for the actual tuning of the TV.

The converter box itself contains a tuner, so you should now receive extra channels available only to an HD tuner. You should try connecting your antenna as input to the converter box. Then output the signal from your converter box to the VCR. Your VCR may then remain connected to your projector.

You may simply think of this as if you are inserting the converter box between your antenna and your VCR, which should be currently connected to receive an over-the-air signal. Remember, as the tuner you will be using is in the converter box, you will need to change channels using the converter box, not the VCR.

Thank you,
Jason,
Go Ahead. Use Us.

Bom dia!

If you mean DVB-T signal then you will need an extra box to receive this via a normal antenna if your media receiver does not support digital free-to-air (I don't know your model because I am not familiar with non-european types). At the moment I don't think anybody transmits HD on terrestrial digital. Satellite TV can provide HD transmission.
