[QUOTE="Piggie, post: 21688, member: 2941"]Amps, overload and noise floors have been known for almost a century since the first tube receivers were built. So it's very old knowledge. It's all about "wireless" being rediscovered. Typical for everything in life and history of something being "rediscovered". There are always those during the rediscovery process that ignore old data simply calling it old and saying this is today and past knowledge is irrelevant since it's now the future. I simply call it not knowing or learning from history. I can tell from things posted here from time to time, regardless of how many times I say that an amp DOES NOT boost the signal making the antenna perform better, someone eludes back to the fact amp increases gain. Hog wash! It's a mindset of being bombarded by incorrect information, and misunderstanding. Granted the difference between antenna gain and preamp gain and what it accomplishes seems elusive.
