[TowerTalk] FW: Dipole gain?

[Matt]

A dipole in free space can be mathematically shown to have a theoretical
far-field gain of 2.14 dB over an isotropic radiator.

Even if this is not the "right" forum i still think this is the place there
I can get an answer.


I was told (a long time ago) that the dipole had a 3 dB gain over the
isotropic radiator maybe even a little more. That way you should subtract 3
dB to get a comparison between an antenna gain give over the isotropic. I
was also told that two crossed dipoles were as close to an isotropic
radiator you could get. Now I am reading more-and-more articles that state
that the dipole has a 2.14 dB gain over the isotropic. ??? Can anybody give
me the "true" about this?
