Try using the Cushcraft A-144-20T yagi, all you have to do is move one set of elements a 1/4 ahead of the others. I have done this and it works well. The other 435 antenna I have is a homebrew 10+10 which is RHCP. I can send you all the dimensions if you want, email me direct. The M2 436CP30 yagi is another way to go. At this time I have 5+5 on 2 meters for the downlink and 10+10 for the uplink and I can start hitting the birds as soon as the outer ring comes into view from my QTH.
