Maybe a bit of both. The antennas are side by side. I am more than familiar with diversity from my audio engineering days. I'll put the antennas on a switch and try this and that. I suspect that a 6dB gain antenna will yield the best all around performance. But then again maybe just a 3dB stick. The 9dB stick will do great across the ridge, but not well down into the canyons where the HT's will be. Only experimenting will tell for sure. I'm waiting for the controller to arrive so that I can assemble the final pieces. That's all that is holding up further tests. It is snowing quite nicely, but the antennas are already up.
