Re: [DIY] TV HD antenna?

 

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?)


>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...
