Shucky durn, I never cease to be amazed at what I can do with my "mighty
5 watts" to an antenna "Proven to be a few dB better than a dummy load
buried 6' underground." This antenna is 28 to 40 feet high at the
center, a 130 feet dipole, configured as an inverted V, with ends about
10 feet from the ground. It's on "average terrain" fairly level for a
mile in all directions. Base elevation is 817 feet above mean sea
level. Empirically and anecdotally, I note that when I take the
trouble to elevate the center of the antenna to 40 feet, I seem to get
better results than at 28 feet.
And, when I get to a higher location - which can be as high as 1050 feet
(in the highest "knob" in the county), or even 920 feet (an elevation at
which I found myself during the Michigan QSO party in 2014) I note
considerably better propagation with a very similar antenna and power.
So, as you say, height does matter. I'm sure if I'd find myself at a
location high in elevation above mean sea level with a contest grade
antenna farm, I'd do even better.
Operating from here in Michigan, at 43 degrees north, is considerably
different from my location in SW OH for some 45 years at 39 degrees north.
All of the above are anecdotal observations, I admit, but quite
surprising to me
it seems very difficult to "level the playing field." Even the WRTC
2014 contest planners found differences in antenna performance from site
to site, and the luck of the draw affected the outcome of that contest
to some extent. I don't fully understand the mathematical analyses done
for each operating site, but differences of 1.5 dB or more in some
directions between the sites, were reported, particularly toward
Europe. Did this present a challenge to those with the lower
performance, or provide a "boost" for those with a higher scores? Even
I noted differences here, on 40 and 80 meters, where antenna orientation
should not have had much effect, some of the 1x1's were LOUD on these
bands, and others were only moderately loud..
It "probably" would be a good idea to have a "Tri-bander/Wires" category
for the ARRL contests, similar to what the CQ contests have. It would
give an illusion of a "more level playing field" but there are many
other variables to confound the situation. Things like "Height above
Mean sea level" and "Height above average terrain" both affect
performance. Maybe, asking everyone to call CQ at appointed times (not
all at once, but on a randomized basis) and analyzing the results from
the Reverse beacon network to get an idea of the effectiveness each
contestant's station could be a basis for a multiplier or divider of the
total score?
Such an analysis would seem "way too far out." - and too esoteric in
practice.
Perhaps we contest ops should stop being myopic, fixated on our small
(and seemingly shrinking) sub culture? Perhaps we could spread out
amongst the general ham population, proselytize the masses and build
support in the next generation? Could this happen? Or, are we all a
bunch of olde fogeys who will do nothing except die off in the next 20
to 30 years? I talk up contesting at any chance I get at local radio
club meetings, at hamfests, etc. Only a small number of "suckers" errr,
newbies are attracted, so maybe my approach is not working. Ideas on
how to solicit more newbies?

After every contest in which a relatively large number of "casual" operators are worked,
I receive many QSL cards which state the antenna is a "wire antenna in the attic,"
multiband vertical, or other marginal antenna.
