Just a hint for you, if the set screws on the capacitance hat ( horizontal elements) and the threads on the angled elements do not have thread locker on them already, I would recommend Loctite blue thread locking compound. Do NOT use red ! Blue will hold the elements in place, wind over time will vibrate the elements loose and one day you will look up and notice missing elements. Red Loctite requires high heat to break the bond, high enough that you will ruin the antenna to take it apart. Blue will hold the elements in place while still allowing you disassemble the antenna if necessary. W1VJL

@@jdock32778 it acts as an insulator but enough of the element should still be metal to metal contact that it should not be a concern, you only need a very small amount don't completely cover all the threads and most also have a locknut on the element to tighten against the hub don't use it on the locknut if one is provided, the locknut will also provide a path to the element from the hub. If it is the type where an unthreaded hole is in the hub and you just slide the element into the hub instead of screwing it in and there is a set screw to hold the element in place, Loctite on the setscrew will not affect capacitance

Josh ... love real life "lessons learned" presentations. I originally had one of these Diamond D3000N discones. I just replaced it with a new Comet DS-150S Discone Base Antennas. I also have an RSPdx that I have dedicated it to. This antenna does not use set screws, but, all of the shafts are threaded with a lock nut. All of them including the capacitive type hat have black plastic covers on the ends to protect your eyes. I routinely use this antenna for all of my HF listening as well. I find that the S/N ratio is much better than my full length wire antenna that I have in a horizontal plane. Keep up the good work! 73 - KF6IF

I started out with a Tram discone, and a raspberry pi running cubic sdr on debian. That's what sent me down the ham radio rabbit hole. The Tram is a lot easier to put together and has an 11 m whip and two longer tunable base whiskers that do 10m , so I also successfully used it as a cb antenna (for local stuff) before I got my ham ticket. The transmit range is very limited though - I never made any CB or HF contacts with it outside of maybe 10 miles away. Discones have BIG EARS - I can hear VHF/UHF/GMRS repeaters 80 miles away in other states with it, mounted about 30' up in the air... and I live in hill country. You're going to love it for SDR and scanning. The downside is that discones have zero gain/directionality. So you won't get out with it past 5-10 miles on transmit.

I've done dx to NZ & Aus, all over North & South America and Europe on 10. I haven't been able to beat it with anything I've tried so far on 10m including dipoles.

@@aandpman You must have caught some magic sky to DX with a discone! The best I could do with the tram on 10m was a guy in the next state. Maybe is has something to do with 10m being a "daytime" band and time zones - I'm an east-coaster with a 3 in my call, so most of my DX window on 10m is closed to the east across the Atlantic, by the time the band is warming up for me. I did hear a lot of Caribbean CQ's, but I never could hit them. I normally can't hear west of The Rockies, unless the caller is pumping some serious wattage. I have mine on top of a 10' stick of 1" galvanized conduit, that I hose-clamped to the top section of a 25' telescoping flagpole that I bought at Harbor Freight. When I'm not using it, I just collapse the flagpole, and it's hidden behind my garage. I got the idea for the flagpole setup from a power antenna I had seen on an old Buick.

Caveat Emptor : It has been my experience, that over time, if you don't tighten the elements properly, that exposing these antennas to various wind speeds, they will respond to the vibrations, and lose elements ! I have learned to combat those vibrations, by incorporating a UV resistant monofilament fishing line, tied to each long element around the skirt of the antenna, in daisy chain fashion ! Knoting the line around each element as you go ! This, if done properly, acts as a damper of sorts, helping keep those pesky antenna disassembly vibrations to a minimum ! 🤔.....? Just a thought ! Addendum : I would also suggest if the model antenna you purchase doesn't have nuts for each element, it would be a wise investment to purchase the appropriate size nuts, as when tightened appropriately, they aid in helping keep the elements from backing out !

I would imagine if it performed as well as this one and still covered more, that the demand would be high. Am I right to question it or is Moonraker usually pretty reputable?
