Got a Sirio m 400 Star duster

Now I have to find the right size pipe to fit the hub...of the antenna..

I can't remember what size I used. Water pipe is measured by inside diameter, I believe. Your best bet would be to take the hub with you to see what fits. I do remember cutting the threaded portion off the pipe so the hub screws could get a good bite on the straight part of the pipe.

The Rule of One

One Man
One Radio
One Antenna

Undertaker, it’s E-Z.

Just change hats to be a different man. With a different radio.
With another antenna



No one will notice the extras that way.

Yep I should have known take the DAMN hub!! This is what happens when you have been around chemicals for 30 years. They mess with your bean...

I am the King of getting to Lowes or Home Depot and not having what I need for comparing or measuring. And I haven’t been around chemicals.
Radiation yes, but not chemicals.

It feels like I spend more energy in writing lists, measuring and such than ever before. Not that it’s a problem to have to do so (organizing is half the fun),

- But then I leave the list behind.

- Believe (could swear it, by crikey) I ordered the KEY supplies off Amazon.
Nope

- Get project vehicles mixed up.

Etc.

I was thinking about 10 foot sections of fence rail . where can I find the electrical pull box? Sounds like a great idea...

Hardened electrical conduit is stonger than water pipe.
Used it for a mast on my 4 element yagi when it was up.

These are the directions for the original AS m400. Takes 1" threaded which would be MIP male iron pipe thread or 1 1/4" steel mast min 10'
I dont know how similar they are but maybe this will help.

I agree, unless you are only shooting for ~30'.
For heavier I can buy used oilfield flow line for far less than rigid plumbing.

You probably are already aware, but be careful cutting welding and grinding on used oilfield pipe it’s almost always full of radio active scale aka norm. A lot of scrap metal places wave a Geiger counter over it before they will even accept it.

Yep in the 1980's I was an oilfield welder....

HomerBB,
what's the best height for the Starduster to have the best all around performance local/dx?

 

[HomerBB]

If you want local, 9' to 43'.
If you want DX, ground mount it, or go to 52'.

Can't tell you about all around. Mine is at 44', but no real DX conditions right now. Worked out from 300 to 1300 miles. Nothing internationally.
Works fine locally.

Here's an original antenna specialist if you've got that kind of dough to throw at it
