EV's Best Top Rated FM and HD Radio Antenna Guide & Reviews
No offense taken! I know Hogwash and you have it right, it's Hogwash....
Actually stir fried, with lots of garlic hogwash is good served over Jasmin rice.
If you want a vinaigrette mix olive oil, wine vinegar, balsamic vinegar, fresh basil and oregano, with fresh squeezed garlic. Mix all ingredients then wisk in the oil.
It's also good any turnips you root out of the ground also.

No the Terk Pi is amplified with adjustable gain on FM, passive on the fold out AM loop. It really looks like a good antenna, from reviews, comments, and information that Ive been gathering on it. Its got an antenna designed by Larry Schotz for compactness, yet still rendering solid performance. The AM Loop is great too.....you can buy straight up AM loops that really work well....like the Select-a-tenna, Terk AM Advantage, Kaito/Grundig AN 200/AN 100....its a proven AM design.
Im enthusiastic about it now, and the Terk and Parsec Obelisks (also designed by Schotz).
The Terk FM Plus (FM+) uses the same antenna design without an amplifier....and no AM loop attached. Its FM only. For the anti amplifier crowd.
The Terk Q has signal strength meter and adjustable amp and memory for some number of stations......Im looking into it, it may be something I have to physically try out to understand it fully, but it doesnt seem to be user friendly....another thing you have to mess with for little benefit...when a set and forget antenna would work just as well, and with less fussing about with it.

0db compared to?
It is an end feed 1/2 vertical! yes.....
Besides gain, what advantage do you get from a halfwave vertical over a 1/4 wave vertical? (hint. relates the direction in which gain is obtained.) This gain will often make it appear the 1/2 is way better than the 1/4 in some cases.
Now that case is the question. It is also where the antenna exhibits it's gain.
That should give it away....

Ah, you were there, and I may have asked the question bad.
The maximum radiation of any vertical is at some angle between 90 degrees (orthogonal to the whip) and all verticals have zero (well it approaches an asymptote) off the end of the vertical (provided it's a pure vertical radiation, ie no capacitance hat). So if you look at the vertical from space the radiation looks like a doughnut.
Now just like stacking antennas in phase the radiation from each if spaced correctly will add to create at some angle to the antenna there is more radiation (hence less somewhere else) and we call that gain. Adding two antennas is like the 2 slit experiment some of you may have done in physics class, where there is a bright spot on the wall between the slits (where there is no slit) cause by the summing of the waves passing through the two slits.
Now since a 1/4 wave maximum current is at the base of the antenna near the feed point it's maximum radiation above a good ground plane is about 25 degrees above the horizon.
Now think of an end feed 1/2 wave as two stacked 1/4 waves. Since the antenna is feed at a high impedance point where the current is very low, all the energy is "pushed" into the antenna by an electric field. As the signal approaches the center of the antenna the current builds to a maximum at the center. Now the strongest magnetic field is created where the current is maximum as shown by Maxwell.
Hence thinking of a 1/2 vertical as two 1/4 waves stacked, the current is maximum at the top part of the bottom half and the bottom part of the top half. Hence why I say it's very close spaced stacked verticals. Still there is some gain. There is a about .85 db increase from the "stacking". This lowers the radiation maximum to about 20 degrees.
So with lower radiation maximum, more signal is receive or transmitted closer to the horizon where the signal from distance stations is also maximum.
Though only .85 db gain (over a 1/4 wave vertical) it will appear one is doing better than that. This is because the antenna is then aligning with the maximum signal coming from the horizon.
After that much typing I hope I kept to the point and answered my own question.
