There Is a Better Antenna Waiting To Be Discovered
The number one name in antenna experimenting is Jeff Station8 who has been working for a long time on improvements in metal types, shapes, coils, grounds, searching for more efficient antennas.
I (Carl Blare) also enjoy messing with antennas and my two favorite measurement tools are the Spectrum Analyzer and the field strength digital indication on the TECSUN PL-310 radio.
We even have a transmitter station, KHZ 1640 AM, dedicated to "Indoor Experimental Antenna Project", hoping to collect useful information for the many micro-broadcasters who are forced to operate from an indoor location.
Some old-line engineers have said "The best antennas are located outdoors away from surrounding physical objects", and so far that is a fact. But because I have a retarded imagination I like to believe that the only reason we don't have better antennas is because engineers have not spent enough time working on the problem.
Even licensed HAMs have written articles about their apartment buildings not permitting outdoor antennas, so they are always working on ways to get better results from indoor set-ups.
There is an experiment coming up this week in which I want to find out... what are the field strength differences between a 5-foot AM antenna (Part 15) and a 10-foot antenna? Is the increase in range-per-foot of antenna a linear progression? If so, it could be extrapolated upward to estimate the potential field strength of a 20-foot and 30-foot antenna (which of course can't be actually used under Part 15).
