We have always liked Yagis better than grids. Additionally, we prefer higher gain (tighter beamwidth) antennas with lower transmit power. Of course, with 900Mhz is can be tough to get higher gain. Besides going the parabolic route, which is problematic with 900Mhz; you can look at using loop yagis. Checkout the following:

I have a situation where interference is playing a part in degrading my signal. I am currently using flat panel 13db antennas. I want to try a yagi or grid (been looking at Pac-Wireless) to narrow the beam and hope to overcome this problem. We were fine until the leaves fell off all the trees- they must have been guarding us. So, does anyone have a comparison or preference... they have a 13db yagi, and a 15db grid. Other than the fact that a grid is not cosmetically preferred, what kind of results can I expect or is there a preference of yagi type or manufacturer.

Thanks in advance-
