Body
On discones
I got one sent from Canada as a gift a harvest 130 and bought a second one a tram 1411
I modified the harvest to take a long 3/8- 24 threaded rod and can use any standard or complex whip with it , will use a 11 & 10 meter whip
will also modify the tram one as is sensitive to water intrusion and failure
idea is to be able to use The TYT 9800 in its full spectrum capability eliminating the design failure flaws that will end burning it ,,,,
today's antennas are a bunch of crap , junk , not to mention the radios !
currently i had not set up base , using portables at the time ....
its evident i will have to make my own antennas , thinking in ISS and satellite
my time is real tied up lately ....
on the networking comments you need to deepen your knowledge base
as to work solutions on the specific things you want to work in , in data, time is the key and if you don't regulate the specific phase shifting in your antennas and feed-lines you will be screwed big time , you will have a mess of a QRM crossover problem .. ( try building an oscillator frequency entangled toy radio walky talky pair) you can talk & listen on the same entangled phased signal , distance and placement is critical .. de-phasing the audio avoids feedback .. ( then apply to network enhancement )
I tend to run away from WIFI and 5G even being able to work WIFI 40 miles .

(use stainless steel screws ! ) and shield yourself to avoid brain burn !

Hector,
I was thinking of a MIMO phase synchronized burst so packets conform to the modulation rather than the other way around. This way one could use the hyperbolic accelerated circular polarization and retain some spectral density at a high Q factor narrowband. Futureshit as the transcoding and modulation would require some serious calculations realtime. Yeah an LP would work great for this, perhaps an othagonal pair.
Hey did you setup a diskcone antenna for your emergency comm or yagi or LP with a rotator?
It's hard for me to grasp the parabolic transmitter antenna on voyager doesn't spread enough to loose all signal by the time it gets this far, what is the tightest RF beamformer you know of?

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?
