"It's All a Question of Range with Part 15 AM" [https://www.hobbybroadcaster.net/community/index.php?topic=7248] :
|An example install.|
I had another similar installation (about 20 foot, single ground rod) but with a ground conductivity of 8, in a congested area, businesses and tall condos and motels surrounding it, etc. and my range fared about the same as described above.
Now, neither employed an engineered ground with radials and so forth, but I assume with a good engineered ground both those previous installs could have achieved a good signal at around a mile (2 mile radius). But note both described involved more than the 3 meter limit, so were not actually to the letter of the law, at the time it didn't really occur to me.. I wish I had tried it at ground level (like the challenge did) and see how the range was affected.
What I'm getting to is that based on my own experiences, I find it extremely difficult to believe that any legal install could ever possibly achieve greater than a 2 mile radius. But putting my own experiences aside, historically, the range capability of 15.219 has always been documented anywhere from 1/4 mile to approximately a mile maximum radius, dependent on the area.. So is it possible to legally achieve a 2 mile radius with a usable signal??.. With a premium transmitter and a optimal engineered ground in a high conductivity, low interference area?.. Perhaps, maybe, if your really super fortunate. Maybe, just maybe.

Yeah, about ten or twelve years ago I have had a Rangemaster 40 or 50ft in the air tied into a massive ground system and achieved an easy 10 miles range of usable signal here on the coast, but it certainly wasn't legal.
That's my take on the matter, based on 75% factual and 25% speculative. But I'm no real expert.
