On the contrary if using MIMO networking topology you will have to broadband in order to execute multiplexing of several receivers & transmitters being simultaneously sharing the antennas and or array . a log periodic antenna structure may be more efficient., making it omni-directional thats a horse of a different color (think discone or double cone ) Or a microprocessor controlled phase array as data distortion will be a problem with increased data rates ..well depends on your application ... and type of encoding & digital modulation scheme you use and its error correction method .
Spatial multiplexing will give you more efficiency in data rates & spectrum usage ....( alike internet time packet channeling ) turning on & off duty cycles of several antennas RX TRX ......

Thanks Hector very cool insights! Add in staggered phase polarized nodes and the antenna gain could go up exponentially but would likely only work with burst modulation techniques so the spectral density would likely drop unless the nodes were MIMO.

Well that is something that can be experimented , i see there is much loss in the transmission line used for RF and if we see the input power does not reflect any gain in the conversion from DC to RF in the resultant terminal power transmission other than the antenna multiplication factor ..
then lets say we have a FREQUENCY amplifier with a unity power factor non RF (non-radiating power signal ) feeding a phase shifting impedance network at the antenna that changes the Phased POWER signal to non phased RF. will multiply the power by a factor of seven within the antenna RF emitting nodes. coupled to the natural antenna multiplication factor , you can imagine , what is pumping 100W NON RF phased signal into a De-phasing impedance match resonant to antenna element and getting 700W RF effective power at a dipole ...
RV goes farther than anyone can think ... its just not just motors & energy savings ..

Hector,
If one has a perfect impedance match to a transmission line and antenna
for a 1:1 swr is there any time a reactive power factor transmits
further than a unity power factor maybe with a certain asymmetric
antenna design?
