Dear Bryan, LF Group, ERP is defined by the field strength at a point distant from the TX. Field strength is a measure of how much signal is present at a particular point in space. Of course, if you

Well I always thought there was a large loss depending on the extent to which polarisation differed between emitter and recvr.? This is from qsl.net: :-....... Notes Polarization Mismatch Loss (dB) =

Hello Bryan, thank you ........and is this comparison half-wave antenna vertical or horizontal ? Are there limits about how far away is the 'notional measuring' position . The reference antennas for

Hello Bryan, ERP, EIRP, EMRP ... It's just a matter of what reference antenna you take ERP is the power which would be required to be fed to an 1/2 WAVE DIPOLE antenna to achieve the same field stren

Gentlemen, I have long been fully familiar with 'isotropic antenna ' and 'Effective Radiated Power.' ......indeed I hope no-one can get a transmitting licence without such knowledge but......... ERP

Bryan, As others have pointed out, the "I" is for isotropic, a theoretical radiator that sends the same signal in all directions. A 3-D model of the radiation pattern would be a sphere. The far field
