Antenna Diameter : 1.25 meter
Freq : 7.25~8.4
GHz
Efficiency : 60%
First Sidelobe level
: -14 dBc
Sidelobe
level : 32-25log(theta)
Type : (Cassegrain.
Gregorian, ADE whatever)
It's very hard to
satisfy that spec (SLL).
This Antenna is 30 lambda
big, and our customer request 32-25log(rheta).
(It should be 52-10log(L/D)-25log(theta) by ITU
Recommend Regulations though)
If anyone knows
any product, please let me know...
