Test mounted my new HF discone in the loft. Good signals down to the 60khz time signal, VHF/UHF ham bands were dead which is probably about right. Hopefully get this up outside soon but will need a much more robust aerial mast first.
@kr4dio unlike that one, I don't think mine is resonant on any ham bands. Even if I can tune it up it'll probably not be a very good radiator. I might try some day but it wasn't intended for tx anyway.
@M0TDN oh, I see. I’ll have to keep that in mind if I ever get around to installing a real antenna for my rtl-sdr — for now I just have a long wire.
@kr4dio it's commercial (https://www.moonraker.eu/scanking-hf-discone-0-05-to-2000-mhz-antenna?___store=english). It is about 6 feet tall. I suspect the top section conceals a coiled up long wire or something but didn't fancy dismantling it before first use to find out. I doubt it is as effective as the full size model but it lets me scan the full range of my Airspy+Spyverter without switching antennas so it's a decent solution.
@M0TDN Nice! Is that DIY or commercial? I was under the impression that a discone would have to be prohibitively large (25m tall?!) for HF.
