dBq, don't see that reference mentioned very often... I think its been years since I've seen anyone mention it...

Unless you are over a body of salt water, the ground in your area is nothing like a perfect ground.

When referring to vertical antennas, a 1/4 wavelength antenna that has the same tip height as a longer antenna, say 1/2 or 5/8 wavelength, will have very close to the same amount of gain. There are exceptions of course, but this is true in most cases.

I wouldn't dwell on the figures you see for dBd and dBq. Yes, they have 2.15 and 0.15 dBi gain, but only in freespace, which doesn't exist on earth short of being inside an anionic chamber... Once an earth is present, it dominates the gain and radiation pattern of all antennas.
