A friend of mine bought me for tests the special holder and two narrow LNBs, to check how they perform. Main point of interest was to receive 13E+9E in multifeed configuration. Since 9E signal is quite low here (on 1.2m during the bad weather certain TPs fade away), I've decided to test it on my 1.5m offset dish (BILSAT made, Turkish company). Results were disappointing - signal strength is low,compared for plain LNB. For example, where I'm getting SNR 5.2dB with cheap LNB, with these LNBs I got only 3.4dB. I will try to conduct additional tests on dish with wider opening angle (speaking in plain terms - cheap and smaller dishes), because, during the adjustment of multifeed configuration, I've spotted weird, but interesting situation. Say, 13E is in center, so LNB at the right, next to it will be 9E. The 9E LNB will give the best result in that case. But, if I move it further to the side (say, to 5E position), but rotate it with it head pointing to the left side, I'm still getting the strong signal! this clearly indicates that dish illumination area clearly is out of LNBs feedhorn shape, so specialised dish may be needed.
