I show you how I built the feedpoint for the tri-band Elevated Radial SkyLab Starduster. Now, it's 15m, 12m and 10m target frequencies. Will this work? I don't know yet..! Callum.

This is a great project Callum! I remember seeing the "starduster" as well as the "super scanner" on the rooftops of many homes here in Oregon. My dad had an avanti pdl2 and the avanti 5/8 wave vertical ground plane on our rooftop. The huge ice storm of 1979-80 rendered the total destruction of the pdl2, not even repairable. The vertical was arched over from the ice load but straightened back up when things thawed out.

The Starduster was one of the few commercially made antennas that didn't have a DC ground to the radiator. It has a low angle of radiation and it had good frequency range. It compared well to coaxial and 5/8 wave antennas. Supposedly it was rated for about 800 watts. I ran one with an Alpha 374 amplifier, with 3 ceramic tubes and it seemed to work alright, but when I took down the antenna, the RF had arced through the RG-213 coax to the mast pipe and melted the cable's jacket about a quarter wavelength down from the feed point of the antenna. The antenna was still working fairly well though.
@DXCommanderHQ

Ah-ha.. If the components had a reasonable rating, it should flash over.. I gave mine a squirt at nearly 2kW the other day and all good.

Callum, I bought one of those 59 foot fiberglass poles from you specifically to build this antenna. It’s arrived and I’m ready to start. (Nicely made, alarmingly quick shipping!) I see you used 3m of wire for each of the ground radials, but no mention for what lengths you used for the 28 MHz and 24 MHz vertical elements especially the 21 MHz bit with the fold over (total length of wire and approximate fold over length?) I might be contacting you by email for the plastic spacer between the plates if I can’t bodge one up. Thanks, Dave K2CZH

I am really looking forward to the results from the build as this is a concept I also thought about when my antenna farm was constrained to a roof too small to hold a 40m dipole. I didn't have a proper pole to try it myself and share the results but I'm sure you'll tinker enough to make the bottom part work without having too much interference from the line to the top part. Also I am really looking forward to you making a self-supported DX Commander antenna of any type without guying, as I have a great location for it and will most likely get one to put on top of a building with height 45m AGL with strong winds.

Unlike metal parts and their shavings, the nylon does not conduct heat, so all the friction heat is in the drill bit, I am unsure of why not just build verticle dipoles, I assume the angle of those radials makes the take off angle lower?
