Sg 7900 High Swr
Click to expand.EXACTLY! Gain is not everything. I used to run a Diamond SG-2000HD antenna which is also a 7/8 wave. It was great for simplex mobile-mobile but was almost always beaten by a simple 1/2 or even 1/4 wave antenna when working repeaters high on the hilltops from the valley floor. I later switched to a Comet CA-2X4SR because of that and also the need for wider bandwidth. For somewhere on the great plains a 7/8 wave antenna is great. As for the 'picket fencing', or flutter, I actually had less with the 7/8 wave antenna then any other type.
I run a Diamond SG-7900 now and also have a Larsen 2/70B.it's been really interesting since I've been involved with a 440 repeater setup recently to experiment between the two antennas. 440 is quite a beast to figure out.I've definitely found the 7900 to be better for 2m simplex, but on 440, they both have their plusses and minuses. The Larsen shines on 440 with rolling hills and varied terrain, but the 7900 will kill it given long wide open clear shots to the machines. It's a tough call and I've been swapping them in and out fairly frequently trying to decide if either one is the 'winner'.
