The 13dBi gain is what causes the ERP to be so high. It's what causes a relatively low transmit power to be represented by a very high EPR. Because the gain is so high.takara wrote:And 13 dBi antenna gain. Don't know about Nottingham would think that signal could be heard in Devon.radtech wrote:
Presumably power output was meant to be 10W not 100W as they've been licenced for! Also odd that they've been assigned 25khz channels.
The actual power output from the radio will be much much less. 100W is the ERP coming out the antenna, factoring in gain of the antenna. It stands for effective radiated power in case you didn't know.
