So I want to make a high altitude ballon. I have my ham license so I was planning to use the 433mhz band. I have some hc12s I would like to use for it. The hc12 gives of 100 miliwatts of power. I need at least 1 watt. Can I use a rf power amplifier to boost it to 3 watts? I found one on eBay for 20 dollars. If I can, I think that's better then buying a 100 dollar 1 watt rf module online.
