Basically I'm getting a 5.5km antenna for a project but don't know wether a 1W amp would be enough to be able to get this sort of range. I also don't know where to get this stuff I've found the antenna but not the amp, I'm thinking of about 2W. Any know of anywhere I can get some stuff second hand as my budget is not unlimited! And would this pose any threat to my health with the antenna being mounted on the side of my house where I sleep. Thanks.
