Okay folks,
I know this has been beat to death, but I cannot find anything on the web to answer my question so i am bringing it to the experts. The manual says the MPE radius is 10 ft horizontally away from and 16 ft vertically above a persons location when transmitting. Well my boat is only 16 ft, I do not have a tee top, and my only mounting location is along the gunnel. Now in the book is also says that this range is needed for a 25 watt radio with a 9 db antenna. (200 watts transmission). I have a 25 watt radio with a 3 db antenna. (50 watts transmission). Since my actual broadcast power is 25% of the maximum value can I reduce my MPE radius to 25% (2.5 ft) or am I over simplifying things? Likewise, if the radio is broadcasting at 1 watt the total transmission would be 2 watts. Would the radius decrease to 0.1 ft (1.2 in)? I have searched for an equation that I could use to determine the radius but I have had no success. If my estimation is correct I could get the horizontal separation but the vertical will still be a problem. So could I keep moving the antenna away horizontally to compensate for the vertical deficiency? Lastly, am I correct is assuming the MPE only applies to when I am actively transmitting and not when I am in standby or receiving a transmission?
Thanks in advance
