Hi folks,

I have some questions. If I had two power amps at 15W each, 2 feet
apart, and they are connected to two similar isotropic antennas, would
the two far-field patterns add up? How would I calculate the power
received by a receiver at a certain distance?

I wonder since each antenna will have 0dB gain, then ideally the loss
that I would need to take into account would just be free space path
loss, eh? Will the antenna patterns change in terms of beamwidth and
gain? What other changes/factors do I need to know about?


Interesting proposal.
Interaction between the 2 would depend on several factors.
Your only stipulation is that they are 2 ft apart, so...
The frequency would matter and [[Relative]] lengths of coax to each antenna
would also matter.
Its possible you could have a phased array.
Under certain conditions gain could be broadside to the two,
in some other conditions, gain could be endfire.
Its probable, though, that all you have

is a mess.
