buy a motorola or similar RF module. aka a "CATV Brick" or "CATV
AMP".
cost 60-90$ US.
usually runs off 12 or 24 volts, and get the app note/manufaturers
data from RF parts
make sure you have a good RF wattmeter and adjust the source before
the amplifier to avoid overdrive. overdrive is BAD. It will need a
heatsink!
if your really transmitting with it, put a filter on the output as
many of those modules have bandwith from 0 to 550 mhz or so. The law
says any harmonics and spurs you generate must be about 40 Db down
from your output
time spent building anything else without the proper equipment,is
priceless, and judging from the language in your post, you dont have
the skills/milliwatt meter to do it.
Dont expect this fowarded via email.
