Hi! Under the influence of another thread I have decided to play little bit more with CM 1.2m antenna, namely to convert it to double-reflector design. All I need is to make set of parts (mostly INOX) which will allow to nicely install Fibo bottom feedarm with the subreflector and feedhorn, or even without Fibo feedhorn to play with standard Ku or C band LNBFs. Feedarm, subreflector and feedhorn from 1.2m Fibo or 90cm Fibo can be used here. Actually, set is almost ready, only sidearms are missing (need to buy some INOX 10mm tubes). At the end of the day I will have 2x CM 1.2m installed shoulder to shoulder, one in usual setup and another one in double-reflector mode and then see which performs better. By theory dual-reflector antenna systems should bring ~10% better performance, side-lobes and X-pol minimized.
