THere is a lot of hype out there about HDTV antennas. Most of it is just to get your money

See this?"John N3bvh"
That's his HAMM Radio License number. I read that stuff
from when I was 8, on. (No one TOLD me that there were
kids' books and adult books.) This guys KNOWS from
whence he speaks when it comes to antennas & related.
>Go to www.antennaeweb.org <http://www.antennaeweb.org> . you can put in your location and it will let you know where the stations are in relation to you.
Thanks, John. Didn't know that!
>Keep in mind that not all of the stations broadcast on
the UHF frequencies. I live in Philadelphia, and I put
up one of those HD antennaes and I got about 30 stations,
I replaced it with an old style UHF/VHF antennae and now
I get 50 stations.
Would you still suggest, as I might, to locate them both on a pole
and run dual wires? (& a rotor?)
You dont need to got that elaborate, just buy something like this http://www.radioshack.com/product/index.jsp?productId=3740641&znt_campaign=Category_CMS&znt_source=CAT&znt_medium=RSCOM&znt_content=CT2032189it will get all the TV signals and FM if has a 100 mile range UHF and 60 Miles VHF. The only reason to put up more than one antennae is if you were in a situation when you needed extremly strong signals or where you only got a very weak signal. Then you could get antenaes cut for the frequency of each station and aim it directly at that station. The thing to remember is that with an antennae like this is that it can be very directional. So it would be designed to reject a close signal that was not in its path so that you could see the distant one that was. So a rotor might help.>The bigger the anenna (or longer the rated range) the higher the signal strenght. I would go with a bigger antennae and no amplifier.
I meant the amp for splitting once inside the house.
If you have a 20 Amp circuit and plug 2 things in, each may draw 10 A.
TVs are similar so they each draw TV-Signals about equally.
Plug in 2, and the split that power. Plug in 4 and you are almost
guaranteed a little snow. Beat antenna youi can do, THEN a
splitter/amp, if you see snow and run extra TVs. With a crummy
antenna, an amp just amplifies the snow.
> that you need to ground your installation. If at all
possible you should run a grounding rod and ground the structure and the antenna. There are a couple of reasons
for doing this, the main reason if the set up ever gets hit by lighting you give it someplace to go.
Versus torching your balcony or house.
> Number two, it will improve your Signal to noise ratio
and give you better results.
Sorta like improving your antenna. Or better tires on a hot car.
>I have been a Ham Radio operator for some 20 years and a decent antenna installed well will make the rst of the set-up sing.John N3bvh EXACTLY True! You don't put a mansion on a crummy foundation.
The signal is sent out to exacting specs. A licensed signal Dr is on
site at all times it is sent to be sure of that, like a pilot in a plane.
An antenna is the literal foundation of receiving a good signal.
Take a crummy photo and no magnifying glass (amp) will make
it better. More see-able, but you will just see bigger flaws.
I like RCA's metallic blue antennas for TV... LMAO! Pretty...!
This VHF will also link to your FM radio!
Now, about your Eight-Track...
