Just in case anyone else is installing the Ryan TCAD, here's what we did on our LNC2. We mounted the antennae left and right instead of top bottom. We used the circuit board type of antennae and mounted them internally on the fuselage sides about 14 inches behind the firewall. This arrangement works great. At first I was worried that I'd miss targets directly ahead due to the firewall, but the fuselage widens up enough behind the firewall to allow the antennae to "see" ahead. We have done extensive testing with another airplane and we get very accurate traffic information in ALL relative positions between the two aircraft. By mounting the antennae internally I'm sure that I must pick up at least 3/4 knot :-) Bill harrelson@erols.com N5ZQ
