What about the lawn chair and b-b gun? Safety equipment is always important.

Now I already had a ptp link to another tower from tower 1 so this helped. I used Google Earth to map out the points and then used the ruler to connect each ptp link. I took the map with me on tower 1 and mounted and aligned the dish. I just eyeballed the direction of the dish in relation to the existing dish using the Google map. I got everything powered up and then went to tower 2. At tower 2 I had a landmark that I thought was close to the right direction. Mounted dish and pointed at landmark and had a signal. I then aligned dish while guy on ground gave signal reports. I have not gone back up on tower 1 yet to tweak dish. I actually have a 67 signal when lingowave said it should be 57 so I do need to align dish on tower 1. I did not want to believe Google maps at first but when I actually got up on tower I could tell it was about right. I have tried using a compass but on a tower the compass will not work correctly. Guess the metal structure throws the magnetic field off.

One team doing both ends at different times. The first dish must be aligned without a connecting radio at the other end. We know how to get uptilt/downtilt/azimuth from Radio Mobile. Uptilt/downtilt is easy to do with a simple gauge. Azimuth is a different story. If you can see the site that you're aiming for, no big deal, but what if you can't? We have a number of backhaul upgrades to do in the next few months, and we have alot of fog here in the mornings this time of year. -- This message has been scanned for viruses and dangerous content by the <http://www.dtisp.com/> DTISP MailScanner, and is believed to be clean. ---------------------------------------------------------------------------- ---- WISPA Wants You!
