Thanks for those answers.
The gain minimum as stated is to my opinion overrated.
Have you got an idea how much 30dB actually is? And what you would need to get it?
Just to give a idea...thats at leasti in the direction of 50..60 times 6elements stacked.
It is know that about 14dBi would cover it. (not talking jo-gunn gain lol).
You can hear your own echo's using 5kw and boomlengths in the order of 20...30 meter
This although im certain one could do with less.
So, if one is capable of hearing his own echo's, you could make a qso with someone with similair equipment.
I wasnt talking about voice, but for starters JT65a for example.
There are quite some ways to calculate if the "equipment" and "path" is good enough for a qso.
Probarbly looking at a minium of a kw
and boomlengths preferbly over 36 feet, but then again...who knows...with less.
