Uhf Vhf Hd TV Antenna

I want to do this so that I can continue to receive a few VHF programs through my old combo antenna in the attic and get better HD TV with a new UHF antenna installed on the roof.

Just connect both antenna's to a splitter and run the single connector to you Television. Splitters can also be used as a combiners.

If you want to help save free TV - and YES it is in danger - PLEASE go to to thefutureoftv.org and voice your opinion! Let ypur politicians know ...

I was thinking is it possible to just change out the old UHF/vhf wire and replace it with cable wire and just add a good in line splitter (1000mhz) into the house and maybe add an Antenna amp and branch it into all the rooms since there nothing special about a hd antenna what do you think

I don't think that will work replacing with rg6 and having a splitter with out an hd antenna wont get it. I have installed hd antennas where they a supposed be getting hd and nothing.
Maybe if you have a HD TV with the box inside the tv run some rg6 to the roof, then try the hd antenna.
Just get Direct TV all the channels are digitally encrypted and you get lots of hd.

The prices suck though.

After initial setup, the ten year old analog TVs received most channels, but never close to all the possible stations. After a week both began to lose stations and now one gets no signal at all, and the other only receives 3 channels. I have gone up on the roof to realign the antenna one tv is connected to and changed or moved the set top antenna on the other tv with no effect. We purchased a better quality set top UHF/VHF/FM antenna at a garage sale, with no effect either. Since the conversion was clearly and widely advertised as one in which the previous antennas would work, an HD antenna shouldn't fix the problem. We can watch DVDs and old videos that we have connected up to the converter box as well, so the box itself is at least marginally working.

Lots of misstatements in your post.

First, there is no such thing as a HDTV converter box. They are digital converters. They do not provide an high def picture.

Secondly, the statement "We purchased a better quality set top UHF/VHF/FM antenna at a garage sale, with no effect either". Why do you say it is a better quality?

The fact is, *ANY* indoor antenna is lousy and replacing a lousy antenna with another lousy antenna clearly accomplishes nothing. Price is also not a good indicator of anything.

Fourthly, the statement "the conversion was clearly and widely advertised as one in which the previous antennas would work" is not entirely true. They said you at least had a good starting point of being able to receive a signal but they never implied the reception would be exactly the same because we all know it is not.

Fifthly, the statement "an HD antenna shouldn't fix the problem". At least I agree with this one, but the simple fact is there is no such thing as an HD antenna and I do recognize that many places are selling them. The simple fact is what is important for antennas is the frequency range (UHF or UHF/VHF) and the forward gain.

Absolutely nothing in your post indicated to me that you had any methodology at all of looking at your antennas and evaluating if they were adequate for the task you expected of them. So instead of basing our plans on falsehoods and bad information, lets use some science.

Put your address or at least your zip code in here:

If you keep clicking through, you will eventually end up with a list of stations in your area where the left most column is color coded antenna information. Print that out and come back here if you would like and I'd be glad to provide more specific help, if we know some of your info. There is a lot of good info on these web sites and I've given you some of them. Making an evaluation of the antennas you have versus the color code of the antenna is difficult, but if you click on the antenna pictures and compare with what you have, you will get an idea.

For an antenna lots of elements and a large complex antenna are good things for getting a strong signal. The antenna must be able to receive both UHF and VHF signals.

Price: $119.00 $17.94

Channel: VHF1-12 UHF21-69
Frequency: 45-860 MHz Gain: 22-38dB Rotation: 360°
Support full 360°rotation using the infrared remote controller included in the package
Solid construction with water-proof capability
Rotation speed: 2-4 rounds/min

I installed a TV rotor and a mast mounted pre-amplifier and I can receive a watchable analog broadcast of some analog stations but not even a trace of their HD broadcast. I do receive several HD broadcasts of other stations but there are at least 3 stations where the reception is analog only, even though these stations do have HD broadcasts on air. I have a decent UHF-VHF fringe outside antenna with the rotor and mast mounted antenna. So I was wondering if HD signals by their nature travel shorter distances than theiir analog counter parts? If this is the case are their going to be wide spread
problems for some when the analog signals are eventually turned off?

To some extent yes. As most cities use UHF frequencies for the HD side of things, they travel shorter distances (same with analogue UHF stations) The more significant difference is how directional the UHF HD broadcasts are. Have you rotated your antenna in search of those 3 other stations? You actually need to know the location of each tower for each station. In most cities, these are clumped together in one spot, in others a few stations may be off by several degrees.

Try getting the largest UHF yagi antenna you can. This site should help too:

TV picks up analog great. Roof top antenna is high gain uhf/vhf. ?

If you do a channel scan from your set's menu, the digital channels will be clearly displayed with decimal channel numbers, like 3.1 10.2, 36.1, etc. With the antenna you have, you should get everything watchable in your area, especially if you have a rotor.

When stations do their digital test, what they do is break the simulcast between their analog and digital (DTV) transmitters, then send a PASS message via DTV and a FAIL message via their analog transmitter. (Some stations simply turn the analog transmitter off instead of sending the FAIL signal.) If you happened to be tuned to the analog channel while watching the test (i.e. channel 3 instead of 3.1), you'll get the FAIL signal.

Check the antennaweb link provided by another responder for digital channels in your area that you should be able to receive.
