[Antennas] Unity Gain Rephrased Question

[Dan Richardson]

I sorry but I see that I was unclear in my unity gain question so let me 
try again.

In the mobile radio service industry is it normally accepted that the term 
an antenna has "unity gain" means that the antenna is referenced to have 
the same gain as a 1/4-wave whip?

I'm not seeking the definitions or explanations of "gain" other than how 
the term "unity gain" is used in the mobile radio business.

I had been told, at one time, by a technician (non-ham) that in the mobile 
radio business "unity gain" and the gain of a 1/4-wave monopole (whip) was 
the same and I am trying to ascertain if that statement is valid.
