Hello Folks,

I am a newcomer to the list.

I am still trying to become "aufait" with EZNEC, but I have some difficulty 
with Rx antennas' in that the gain quoted is in dBi. Whilst this is easy to 
understand for Tx antennas, it is only of comparative use for Rx antennas. How 
do I simply convert dBi to Antenna Factor ( dBV/m to dBm ). Otherwise it is 
going to be very tedious if I have to build some of the modelled antennas and 
compare them to a calibrated active loop antenna?!

Another question I have; for example with the EZNEC model of the K9AY the gain 
quoted is -26dBi; is this gain dependent on the matching transformer as this 
transformer is not in the model? Or am I missing something?
