Just to note that the URI test report showed the standard DLM on 3.5 MHz to
have about 2.33 dB less gain than the Navy's reference monopole. That means
that its groundwave field was found to be about 59% that of the reference
monopole.

Some might consider the performance of that DLM antenna to be "degraded,"
compared to a standard 1/4-wave monopole using the same r-f ground.

Correcting myself...

That means that its *radiated power* was found to be about 59% that
of the reference monopole.

Showing my work:

[ 1/(10^(2.33/20)) ]^2 = 0.585, approx
