Where is the antenna wire or plug located from radio to external antenna?


Possible failed amplification unit (may be internal to the radio or may be external somewhere in the car, usually in the trunk or under the rear seats)

Is Clear-Cast TV micro antenna for free TV access a legitimate thing?


The advent of HD TV has allowed for a new round of hucksterism to occur in the TV antenna industry. The televison channel spectrum is the same as it always was but the signal modulation scheme employed now is "digital", which is for the better. Signal propagation is the same as it was and it is not necessary to buy a "digital" TV antenna unless you fidn it necessary to receive TV channels that have sprung up from new directions. VHF and UHF TV signals travel in straight lines and are the strongest when your receving antenna is "aimed" at the transmitter for that channel. Since transmitters are lcoarted all over the poalce, you can eoither use a mechanical antrenna rotator to position the antenna to aim the transmitter of choi ce or use multiple antennas aimed in various directions.

Genrally speaking, the "cheaper" antennas have fewer elements and are thereby less critical to aim. They have a broader beamwidth, so-to-speak, provideing less "gain" in a specific direction in favor or a larger average gain over a broader "angular displacement.

Digital TV signals are not prone to "ghosting" so an array of cheap antennas aimed in several directions will suffice to capture the digital TV signals in your local area. Amplifed antennas are poor substitutes for "real" (passive) antennas placed in attics or as high as possible outside. TV signals are blocked or absorbed by buildings, trees, and such and the signal intensity can vary with the weather and even when leaves are on the trees and when they are not. All your digital TV requires is enough signal in order to work. A small amplified antenna sitting atop your TV may work fine though the signasl is barely above the minimum threshold. When the weather grow wetter, that singal may be beleow threshold and you won't get that particular channel until there is less moisture in the air!
The same is ture, of course, for an antenna placed high up on the roof, but the odds are far better that it will work so much better than the tiny amplified antenna on the top of the television simply becaeu the TV suingal inside the house, at lower elevation, will be inherently weaker to begin with.

Hope this helps you decide.

What is the video single output VHF FM UHF 12db


That sounds like the description of a broadband amplifier. It likely has "F" type (cable-coax) connectors and a power cord.
Commonly used to increase the signal level of TV cable to compensate for inserting a signal splitter, or in some cases to increase the signal level from an antenna, typically outdoor TV or FM radio antenna, so it is connected between the signal source (antenna, or cable) and receiver with antenna as input and receiver connected to the output of this little box. The gain (amplification) it provides is 12 dB, so the output is more than 3 times the input.

Some TV's have poor amplification of the antenna signal, make sure you have a high quality RG6 signal cable, mount antenna with line of sight to TV tower as any obstruction can affect signal strength, AntennaPoint has directions you can use with a compass. If the signal is still low, try a HDTV booster amplifier. If the antenna is indoors, you need to move it around to find a hot spot that brings in all the channels (preferably in the attic).
Buffering on Netflix has nothing to do with the with the antenna, as you have to connect via the web to receive this service. In my opinion, TV's like Samsung are not very good with streaming video, and you are better off using some other device like an old laptop or external device hooked up to the TV to do this.

Cable in my area has switched to digital cable. I own a Hitachi HDTV about four years old. When I scan my channels it will only scan analog channels...the digital channels are an option but I don't...


Unfortunately, you need a set-top box. The Hitachi 65F59 has an ATSC (digital OTA) and NTSC (analog) tuner. It doesn't have a clear-QAM (unencrypted digital cable) tuner.

There are a few DVR set-top boxes with QAM tuners that you can buy separately. (You will need to make sure a given model is compatible with your service. FIOS uses a different option on the Cable Card than other providers.) Alternatively, you can get a cable box from your company.

Retrevo has the manual for this Hitachi TV here: http://www.retrevo.com/support/Hitachi-65F59-TVs-manual/id/371ci977/t/2/ . You will need to enter a code to access the PDF.

If you want OTA HD, you will need to determine the correct antenna for your area and the direction to the transmitters. (External antennas pick up more stations. In some areas amplification may be needed to get a good signal.) See antennaweb.org or tvfool.com for searches on the appropriate antenna to get a signal and where to point the antenna. Antennaweb assumes an external antenna but is very conservative in the received channel list. You would need to set the TV signal input to Air and rescan for channels if you choose to go with the OTA signal.

I wish that I had better news for you.

Alpine CDE-9845, no audio from cd's either normal or mp3. Tuner works fine. Where to troubleshoot?


You have the wrong blue wire connected.
Your power antenna wire is hooked to the amp remote wire and vice versa.
Your radio thinks the tuner is off - and is dropping the signal thru the power antenna wire - and turning off your amplifer.
Switch the 2 blue wires in your install - and you'll be all set.

I installed the zenith Digital converter box lastnight..used an digital amplified indoor antenna..only got 5 channels but today its not recieving signal at all and i bought another indoor antenna thinking...


I understand your issue as not getting the Digital reception from your converter box. The antenna plays an important role in what you can get. If you still have the Amplified antenna try to reduce the amplification and readjust the antenna positions. You might have to do this several times until you get it right. Also, if you live in a city and not a rural location do not use an amplified antenna and see if it is any better.
Good Luck.

Lisa, your set is switched to antenna mode, (roof top type antenna) you need to find the switch usually located inside a little door on the front of the tv and switch it to "cable" position.
If the tv is not that old than it will be located in the tv`s menu listing which is electronically set not a slide or push button, either way that`s your problem , good luck finding the switch it`s there somewhere.

Teac Receiver lost AM and FM


Well, if your unit had that happen, it sounds like it is possible. ;)

I would imagine that the radio, like all the other inputs, is in itself a separate unit or circuit board. If something fails on it, it probably wouldn't harm other inputs or the actual amplification itself... just a guess on my but it makes sense. A repair shop could probably open up the case and visually inspect the tuner circuits to make sure there isn't a short or dead something somewhere.

If there is still sound in Jim's case, I would try a different antenna and/or make sure its hooked into the correct antenna hookup. if sound but antenna change doesnt help, it could still be an internal but maybe simply problem.

i'm no pro but that's my 2cents
