We are toying with making the app available for a small price to the general public, but it will need some mods so you can enter your tower locations manually and store them in a local file/db on the phone. Hit me offlist if you are interested and we'll try to get it out quicker if there is a big show of hands.

If the distance is really long beyond site, such as 20-30miles, I'd agree. But if say LOS within 10 miles or so on a clear day, its pretty easy. After our tech eye balls the alignment, I'll usually have the tech do a fine align just in case we can improve it. BUt 9 out of 10 times, it was not necessary and maybe we'll gain a half DB. The secret to aligning dishes is to look through the feed hole before the feed is screwed in. (for example PAC wireless parabolic dish). You then home in on the far side area aiming for, positionioned in cetner of hole, and make sure the Ring around the hole appears equal size all around to verify it is aligned. Because the hole has metal around it that has DEPTH, maybe 1/4-1/2 inch, you can see the depth of this inside surface all around the hole. As matter of fact, if we dont get our link budget acheieve and we need to trouble shoot why, we check cables first, because the odds of having a bad cable is higher than the tech getting the first alignment attempt wrong. Panels are harder to align, because looking from the side. Sure it can be harder to align a big dish with radome that does not have a removable feed.

You can't align the dish without both radios being powered. You could do two 3 man crews, one at each site. Both install at the same time and they should finish around the same time frame. Align before coming down at all.

Could you use the binoculars to find an object on the horizon on the right azimuth and then point the dish there?

Details: When deploying ptp dishes... 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. ---------------------------------------------------------------------------- ---- WISPA Wants You!
