"He's the leader of the local Socialist club."

We don't have any Socialist clubs around here, but we do have some socialist parks and libraries.

Global climate change? Don't be Daffy!

The temperature of the thermosphere gradually increases with height. Unlike the stratosphere beneath it, wherein a temperature inversion is due to the absorption of radiation by ozone, the inversion in the thermosphere occurs due to the extremely low density of its molecules. The temperature of this layer can rise as high as 1500 °C (2700 °F)

"the legacy of pirate radio broadcasting hip-hop music"

Hip-hop is legacy? Look it up on wikipedia, then look up rock and roll.

"i would tend to believe using highly shielded coax as feedline to the dipole is akin to bringing the TX right at the center fed part of the dipole."

I've seen things that should work not work and things that should not work work before.

6780 is in one of the ISM bands, same (or similar) as 13560.

I must be missing something. Please describe your antenna and feedline for me.

This website:

https://www.tutorialspoint.com/antenna_theory/antenna_theory_full_wave_dipole.htm

Says this:

Disadvantages

The following are the disadvantages of full-wave dipole antenna.

Heat dissipation

Wastage of power

No radiation pattern

No directivity and no gain

Due to these drawbacks, the full-wave dipole is seldom used.

That reminded me, couple months ago I was hearing fighter jets one weekend. Latter that week on the news I heard that there had been an air show and they were wondering why attendance was down 75% from the last one. Well DUH! You didn't advertise it!

Look at the list of things they said were good.
