Discone antennas
« on: December 16, 2019, 2359 UTC »
I'm looking forward to purchasing an RSP Dx SDR receiver and want to utilize the 3 antenna ports. I plan to use one with my 135' OCF dipole, One with a small loop and another for VHF/UHF frequencies. It seems so far like a Discone would be logical for this. I don't know if I will be able to shell out the money for a Diamond discone, but also want to know what a decent compromise discone such has a Tram model would be. My main focus will be HF, but I want to make use of as much spectrum as possible.
Listening on an Icom-718 with a 135' OCF dipole or a RSP2.  Grundig G3 and MLA-30 when portable. When QRP I use a Hendricks PFR-3 I built. Coverage is 20,30 and 40 meters.

The Diamond D130J is a nice antenna, well built stainless construction.

They're all going to perform about the same if they have a vertical element. The diff will be in construction materials, some use cheap hollow aluminium tubing that the wind will eventually break. Pick one and use good coax, lmr, 9913, etc.

I bought a Sirio Antenna SD2000N Discone antenna a year and a half ago, very pleased with it. I wrote a review here: https://www.hfunderground.com/board/index.php/topic,42993.0.html

It's mounted up at the top of a tree, that was the easiest way to get it as high as possible. I used the Big Shot to launch the rope straight up along the side of the tree, so I could have a clear path to pull the antenna up.

I have the mobile one on my car. It picks up Fltsatcom like a champ. And, it looks goofy as heck.
