It can cause nausea and diarrhea, especially in high doses or after long-term use. It might also pose a risk of ulcers in high doses. As a topical treatment, it can cause skin irritation. Caution is advised when turmeric is taken by people known to have gallstones; consult your health care provider first.
Gain is the ratio between the magnitude of output and input signals. Gain controls on an amplifier are basically just small potentiometers (variable resistors) or volume controls, that allow you to adjust the incoming signal to the amplifier.
@BeerHunter125: dBm is an absolute measure of radio frequency (RF) power/signal strength. See the Wikipedia article: http://en.wikipedia.org/wiki/DBm. for the definition of what it means.The reason I mention the above is because you mention as well  Installed an 8dBm gain antenna. Normally, antenna gain specs are stated in dB, which is a signal strength ratio, and not an absolure measure, as explained in this Wikipedia article:ttp://en.wikipedia.org/wiki/DBm. for the definition of what it means.
