In the last years, i have found that some antennas with less gain (or size) can equal to a offset dish with bigger gain/size...why does this happens?
I give three examples:
**broken link removed**
". At just 43cm, this powerful dish offers the performance of an offset 60cm dish.
Gain (dB): 33.0"
**broken link removed**
Digidish 45cm
"The carefully calculated parabolic shape ensures that the reception performance of the DigiDish 45, which has a diameter of only 45 cm, is better than that of many 60 cm dishes - in spite of the much smaller size."
