It might not take as much antenna as you may think would be necessary to make two-way contacts on shortwave radio (as an amateur radio operator putting an HF transceiver on the air). However, often, makeshift antennae are effective enough to be viable. Just look at all the contacts many amateur radio operators make with their low-power (QRP) rigs (transceivers) using short, helically-wound, mobile antenna sticks.<br><br>If they can work magic with such inefficient antenna set…ups, surely your effort at an antenna would pay off to some degree. Right?<br><br>Of course, I want to make a proper dipole out of this example antenna. But, while I wait for the rest of the parts I need to complete this antenna project (pulleys and a ladder, and maybe a potato launcher), I've put this makeshift antenna on the air, with it just high enough so that I can enjoy some time on the shortwave bands.<br><br>With this antenna, I've made successful two-way voice and Morse code contacts (QSOs) with stations in Europe and across North America. I am able to tune it on the 60-, 40-, 30-, 20-, 15-, 17-, 12-, and 10-Meter bands. Reverse beacon detection picks up my Morse-code CW signals, especially on 40 meters (the band on which it is tuned physically). Yes, this antenna, even at its current elevation, works. It works well enough that I can be patient on getting the rest of the supplies and hardware needed to erect this antenna high up in the trees.<br><br>The bottom line for you: just get something up in the air and start communicating. Improve things over time.

What is the most important aspect of life? Having fun! (Of course!). (I'm referring to one of the founding documents of the USofA, "... life, liberty, and the pursuit of happiness...")
Perhaps it is unusual to wax philosophical but to me, this is the most important thought experiment; I am going out on a limb to share a perspective that hopefully is refreshingly new and full of life: Systems thinking -- in my case, an ama…teur radio approach -- but this is applicable to any of our social/societal pursuits.
EACH OF US ARE AN ACTOR IN A GRAND PLAY: LIFE.
We are not autonomous players. We are intrinsic to the whole community, society, in which we pursue life, liberty, and yes, the pursuit of happiness. In any of our smaller communities in which we interact with each other, we have to ponder that we have an impact on others--and a responsibility.
Some thoughts to ponder, regarding freedom of speech, community, ham radio, and so on, consider 2 videos (these are NOT mine):
1. https://odysee.com/…/you-either-side-with-free-speech-or-yo…
2. https://odysee.com/…/Live----Privacy_-Check!,-Freedom-of-Sp…
IMHO, these two expressions are spot on observations and insights.
I'm into amateur radio, a social network, worldwide, via radio communications--shortwave, satellites, moon-bounce, VHF, and so forth. Amateur radio transcends the politics of any one country. I have made some observations that are, when you ponder them, related to this topic.
See:

I concur with the points made in the two videos, above: there is no middle ground. That is a ponderous thought. Regardless of opinions, convictions, we still have overarching responsibility, right?
How we pursue our course in life, what is it that our pursuit requires of us?

Pretty sounds. I picked an atypical configuration of tones and bandwidth for this transmission of Olivia Digital Mode on HF Radio (Contestia included). This is 64 tones, in 500 Hz bandwidth; 64/500. Very robust but very slow. Overcomes deep fades and high noise on HF.

At 13:11 UTC, 29-Nov-2020, the largest X-ray flare so far in new Sunspot Cycle 25 peaked at M4.4 (NOAA scale). It wasn't Earth facing; the active sunspot region hasn't rotated into Earth view. This is exciting! The new cycle may become highly active in a rapid pace... we might see many flares in the coming days, too.

This is exciting! Why? Some scientists are speculating that a rapid start to Cycle 25 will result in one of the most active cycles in recent solar cycle history. Which could mean that we could work the world with a wet noodle, on the 10-Meter band!
With a rapid increase in sunspot activity as we ramp up in Sunspot Cycle 25, the solar flux (the 10.7-cm Radio Flux measurement) will be increasing. That means, generally, we will see better HF conditions on the frequencies above 7 MHz on through 30 MHz or higher.
The bad news is that larger flares cause radio blackout events, because the ionospheric D-Layer absorption increases for the duration of an Earth-facing solar X-ray flare. During this M4.4 X-ray flare, we had a level R1 event, causing some shortwave blackout regions.
