I’ve used the uptilt mitigation technique, but not had any where near the success of just placing a concrete brick on the roof in front of the antenna to block the view of the multipath source (I’m dealing with multipath off the SF Bay in my links).

Of course this relies on an antenna pattern with fairly sharp cutoff at the edges.

We try to get clever about using features on the rooftop, building, etc.. to block the multipath reflection.

We have a handful of customers we have to go out twice a year to move their equipment up 5 feet or down 5 feet. In the fall, I love to point out they just harvested the field across the road, didnt they. theyre always "how did you know" I could take the loss hit in many of these cases to do a splitter and diverse antennas, but would that harm or hurt more? Some of them we just have 2 radios installed a spring and fall radio, we just have them swap which ones plugged in. 2 450b SMs leaves a lot of budget for something that doesnt require touching One of you geeks has to have come up with a solution over the years other than truck rolls. -- AF mailing list [email protected] <mailto:[email protected]> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
