I am trying to increase the working range of cheap arduino 433 mhz RF link modules like these https://www.sparkfun.com/products/10534.
The page says they have range of 500 feet in perfect conditions however in my case it's more like several feet.
So I know I can extend the range by simply applying more powerful power supply, but I thought if I can take the Tx output and feed it into some sort of high frequency amplifier.
I can't buy any here so I'll have to make my own. I am interested if it is even worth trying or will it be so complicated I am better of doing something else?
