hi,now a special antenna is needed in a microwave project.The situation is same frequency must be used but branch angle is 40 degree(SDH link, STM-1, 3+1).
I used Bosch Shell antennas in same situation 6 years ago in P.R.C. It has worked perfectly until today, no interference. I find Shell antenna is showed by Marconi WEB now. But they say they do not sell this product in China for some reasons. so i need a kind of microwave antenna such as Shell antenna, but i can not find likely product in Andrew(catalog 38). My quesstion are:
1.Which kind antenna can i use instead of Shell antenna?
2.What is the right way to purchase?
3.If anyone has details of this kind product,would you please send me by e_mail? What i need are technology parameters and Radiation Pattern Envelope for all frequency band
4.If possible, i want to know the catalog price(CIF China better).
