HOw to build tv transmitter

In this instuctable, I will show you how to make a
cheap analog tv transmitter for channels 3-4.
Disclaimer: I am not responsible for ANY
damage or an laws broken. REMEMBER, talk to
local officials about any transmissions you plan
to make because in some states, THIS IS
ILEGAL, so be warned.
Anyway, if you succesfully complete theses easy
steps, you could get a transmission radius of 5
miles easy. There is one problem, you need to
have some knowledge about antenna lengths and
tuning them. Other than that you are good to
go! ;)
Step 1: Materials:
This is what you need:
1. one RCA to TV RF Modulator- you can get it
at any superstore like wal-mart or at
Radio Shack (even at most Doller Generals)
B. Most mid-90's vcr players of a tv rf
module, but you have to unsolder it after ripping
apert the case.
2. RF TV cable with type-F connecters.
3. One power strip- can get it anywhere
cheap.
4. Any vhf tv signal amplifiers you can get
your hands on. For short range transmission, I
recomend at least two amps.
5. You need one aditional tv amp but this
one absolutely needs a Gain control. It is
Essential you get one of these because your tv
transmitter will not work. Radio Shack does carry
these but they can get pricey. Try wal-mart first,
or online.
6. You need an 75ohm to 300ohm converter
with a copper wire attached as an antenna.
7. Finally, you need a video source-in this case it
is a jazz digital camcorder- and a means of
connecting your video source into the rca
modulator.
Now that you have collected all of these
components, it is time to assemble your
transmitter.
