Starduster was my very first Base Antenna, purchased back in the early 70's from AES in Milwaukee, worked great, never had any issues with stray currents/RF anything like that, though back in them days 150 watts was about my max. Later in the years I ran quite alot more through the original AS M400, never had any issues, even with the old Two Piece D&A Warrior I ran, other then melting my Moms wire core clothes lines

. And the mysterious deaths of more then one small bird

, that was back in the last Solar Cycle Peak
The Antenna was always a decent performer, had some issues with it breaking the plastic spreaders, made up some of my own and never had another problem. While I did prefer the Hygain, and Avanti antennas it was a solid performing anenna which was much less prone to performance changes due to weather. I do remember one though that apparently the radiator filled with water over the winter months and it split/burst from expansion as it froze, never broke, worked fine other then that.. Had one fall over on 40 feet of water pipe during an Ice Storm, a little straightening, raise it back up and it was good to go...
I did sell a few Larrys clones back in the early to mid 80s, never had any complaints on them the 90s Sirio version were very similar, one thing I did learn about the original Starduster is it worked best threaded onto the waterpipe with plumbers sealant, the original matched the pipe threads for somewhere around the 1 inch water pipe, and my Father (master plumber) always had the sweet ass HEAVY DUTY old school water pipe around which came in 21 foot lengths, and was the best you could get for antenna masting

I think at least one of the clones threaded on as well, no need to isolate from the mast...
Not sure who is actually making the current bunch of clones, my guess is someone over in Italy, and imported By H&Y. I'm sure they've lost some quality over the years, just use a bit of common sense when putting it together, if it looks weak, it probably will be, improvise/replace from there.
All that said and done I wouldn't hesitate to choose a Duster Clone over glass...
