unique dish mounting option

Are you confused by all the conflicting and partial answers about the tube dimensions? I sure was. So as soon as I received this mount, I took careful measurements of it and created a drawing, which I've uploaded in the hope that it will help clear things up. (Note to DRM: You're welcome to use it as you wish.)

I have no idea why others are saying that you also need to buy a mast. The expanded diameter at the top of this mount matches the original "1-5/8" Dish tube size, so the antenna should bolt right on. I say "should" because my eaves are 20 feet up and I haven't yet worked out a safe way to climb up there!

There was a suggestion here to use 3/8" lag bolts, but I don't see how they would fit without enlarging the mounting holes, which measure only 0.322". 5/16" lag bolts will fit, but I'll be using 5/16 x 2-1/2" carriage bolts with split-ring lockwashers and nuts on the plate side.

Overall, I like this product very much. I didn't pry off the end cap to measure the tube wall thickness, but it's heavy and strong; the plate is 5/32" thick steel. The tube is beautifully formed, and the welding and powder-coat quality are very good. I expect it to last at least as long as the rafter to which it's bolted.

Works great. I used it to mount my ham radio 2 Meter Antenna. I only wish they would have included screws. Other than that, it worked for my needs.

Worked perfectly for mounting a 10' aluminum pole for my weather station

Really solid and well built. I liked the idea the idea of being able to anchor to a rafter for a more solid base. It does not come with mounting hardware (four screws), but that doesn't bother me.
