How did you manage to space out all the elements so perfectly without a ring somewhere down the length of the elements?
It looks perfect.
One more question, at waht angle is your cone and why did you choose that angle?
I am still learning here...I think we all are :shock:

Hi,Merlin;
I have made a approx.60degree wooden jig that I set my drill press up on,(my stuff is pretty stone-age,but it works!)I spent about an hour measuring the cone/disc blocks for center,and double checked(measure twice,cut once!)-ever heard that one?
The welding rods were purchased from the local shop for about $18.00 for a 5lb box.These are approx.3/16" diameter.
How do I keep everything straight?I have been doing this for almost 20 years,and I guess it's just a little experience.You have to know how and where you are drilling to get the angles right.
Also,you must have patience when working with aluminum!

I wish you had a picture of the mateing block where all the cone elements are connected....
Climb your butt up there and get one!!!!

That is one beautiful job!!!!

Ok! Merlin, 
will do!
Tomorrow(if it is a pretty day) I will harness up,and try to get as close as possible.
Getting ready now to take family out to eat.
Thanks!

That is a very sturdy and good looking discone. I love it.
I saw your other antennas as well. You do very good quality
work I must say.
Kinda makes me wish I was your neighbor, I'd be offering
to take you to dinner or something for making me one.

just out of curiosity, how much did all of the parts cost to make it?

The welding rods are about $18.00 for 3 or 5 lbs(I can't recall)(they have been laying in the garage a few years)the 1/2" alum stock I already had,had to spec order the allen head set screws(40) for $5.00,and other assorted S/S hardware,about $3.00.
It is a very labor consuming job!(cutting the element blocks,lots of tapping the 10/32 threads,and drilling the element holes)Patience in getting the right angles!
I left the cone elements full length of the rods(36"),and each disc element is 13"I beleieve.
I also had to cut out a special piece of the alum stock to mount the support pipe with,which is held in place by the SO-239 connector,in turn,with S/S screws which bolt into the support pipe.
I was just going to build another 8 element discone at first,but decided to go for the 16 element.
16 elements(784") gave me more surface area than the store bought 8 (336")element kits.If I calculated this right.
Bondo filled skoal can insulator I already had!
Everything is weather proofed with black silicone.

Oh,yeah, then there is the challenge of hoisting the the thing up the tower without bending or breaking any of the elements!(this has happened to me before on another discone project)
