[QUOTE="RimaNTSS, post: 1057895, member: 312276"] One of the antennas in my setup will be .98m Prodelin. This antenna tricked me once :eek: ..... When I got it without any mount and feedarms I just measured it's height/width/depth. Height and width were exactly the same, so I've said to myself it is PFA and calculated focal distance, made feedarms, installed LNB and locked signal. But, for some reason performance of the system was really bad. Then put antenna aside. After some time I've got another dish like that and it had mount and feedarms, then I discovered that it is OMG :-doh an OFFSET! Dish is almost as heavy as CM1,2m but long focus one (length of feedarms about the same). Bottom feedarm is heavy, as it was designed to hold Rx/Tx stuff. I've made new, much lighter feedarms and adjusted them to get LNB in focus. To connect feedarms to the dish made adapters [ATTACH]119530[/ATTACH][ATTACH]119535[/ATTACH][ATTACH]119536[/ATTACH] On the picture antennas are tuned to 28,5*E-23,5*E-23,5*E from left to right. [ATTACH]119532[/ATTACH] Have you ever seen how antenna smiles? :) [ATTACH]119531[/ATTACH] If somebody needs original Prodelin feedarms you are free to have them for price of shipping, other-ways they will go to scrap.
