Reflector antenna with very low sidelobe level - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

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
