Chuck, looks great for smaller stuff and tapering towers. But I seriously hope you are not recommending mounting an 8' dish on a 2.5" pipe (item #1 in your PDF's BOM). Every 6' and 8' dish I've ever seen in person needs a 4.50" OD pipe.

The pipe and mount are going to weigh 300 pounds guaranteed... You're not gonna mount a 8' dish direct to a tower, no matter what type it might be, tapering self supported with tubular legs, angle steel legs, or vertical guyed tower.

Do you have any idea how expensive it is to put an 8' dish on a tower??? And have you calculated if the tower can even take the new wind loading of an 8' dish at EIA/TIA 222G calculations for its exposure category? Weight aside the wind loading of an 8' dish is considerable. If you do end up hanging the thing from a man lift I want photos, because there are a few OSHA inspectors I would like to give nightmares to.

If they won’t let me put a 1 or 2’ dish on the tower they run to get extra bandwidth to the school (7 T1’s for 300 kids) or the medical clinic (2 T-1’s), I’m thinking they aren’t going to let me cut down or trim a mile of trees. Everytime I proposed something I was answered with “we have a plan, just be patient”. Not really my strong suit. This plan involves towers but nobody knows who gets awarded or when. So, 2.4GHz through a mile of trees, here I come. I thought of the 2’ dish and see what happens but I don’t want to have to pay tower climbers so do this twice. I’m going to do the 8’ dish on the tower and 2’ dish on the roof. Once I see those numbers, I can make adjustments on the roof. Biggest issue is AF2 through trees. I’m thinking that I’m bringing up a pair of ePMP 2.4GHz radios also to compare. I’m also considering putting up a Cambium 450i 900MHz as backup with a Yagi.

Similar to how they say the AF24 can go up to 10miles, which is effectively bs, the max 99.99% availability reliable range is 3-4 miles almost anywhere on earth that a substantial number of those radios coild be installed.
