I want to replace my Winegard batwing antenna with the Jack Digital HDTV Antenna Replacement Head. The Jack states, "Power it by your existing antenna power supply or use the included power injec...

I'm told by most that the JACK has a wider "Beam width" (The main lobe of the antenna is wider) .. From the performance figures the technician with the spectrum analyzer posted in this thread,, I strongly suspect that is true.
So if you are in the middle of an area where there are stations covering a wide arc.. THEN the Jack may work better.. (or not)
But if your are MILES from the station... The Batwing can "See" Farther, in no small part due to the narrower beam width.
Here is a demonstration, All you need is 2 toothpicks, A state map, a pin and a necklace chain or a length of string formed into a large (necklace size) circle.
Take a state map, and put a pin in the center of it, Now arrange the necklace in a circle around the pin.
This is the pattern of the Wineguard Roadstar omin-directional antenna.. I will add a note here... This is representive of the pattern, the actual pattern and range is going to be different..
The antenna can see stations within the necklace.
now lay the toothpick against the pin so that it points UP and Down.
Streatch the necklace right and left so it forms an oval, about 4 to 1 on the axis ratio.. .. The pattern of the standard Batwing.
now take the 2nd toothpick and put it so one end is against the pin and it's 90Degrees to the original toothpick pointing right.. Pull and pat the necklace so it's egg shaped, Short axis and left from the pin are about 2/3 of the last step.. This is the pattern with the wingman.
Now.. Double the length of the necklace.. You just added the Sensar Pro and cranked up the gain.
Again I say, this is representave it is not the exact pattern of the antennas and it's much simplified. But I have parks where I stay where I need every bit of that range. And the Jack won't provide.
