[QUOTE="Vipersan, post: 856547, member: 325666"] ...well ..thats my curiosity sated.. The homebrew open feed definately works ..but not having the slot as is part of the XMW feed.. As expected a more circular reponse is once again apparent. There ARE definate biases for H or V signals depending on the SL3s rotation ...and overall signal levels are up ...but this open waveguide approach would be all but useless in the event 2 signals used the same frequency but oppositely polarised. Good capture level though.. and no doubt a slot cut in a thin sheet of copper orientated correctly ..and sandwiched betweeb feed and lnb would make the whole assembly more linear selective.. Here are some pics.. [/QUOTE]
