| I run a ground mounted Hustler 5BTV here. Up to a few thousand miles my Cobwebb on 20-10m beats it. Above a few thousand miles the Hustler wins. Talking to a Brazilian station a couple of weeks ago on 20m the Hustler was 2 S points higher than the Cobwebb and my Cobwebb is at just over 30ft up.
Unless the antenna is designed as a vertical dipole all end fed vertical antennas need a ground plane, even those advertised as not needing one. Therefore that means radials which in my case being ground mounted is loads of wires laid out on the grass. If it's an elevated antenna then that means radials. If you don't put those in then the antenna system will use your coax as a radial and you get all the issues that come with common mode RFI such as noisier receive, causing interference to neighbours etc.

| Just to add to this, where HF verticals come into their own is for low angle radiation if you’re chasing DX. This is especially true if you can’t get a dipole high enough to get a decent pattern.
I run a Hustler 6BTV at home, coupled with a 80-10 EFHW running as a sloper and not that high up, and the wire antenna is far better for local nets, NVIS, etc.
Just to reiterate......it will need a decent ground, and that means radials. LOTS of radials. As I was tuning mine, I could watch the tune changing as I added more and more....

| If you want an all band vertical with relatively small amount of radials (25-30) then get a DX Commander. No tuner needed with 6 bands and great performance for a low price. Mine beats a Hexbeam at times for DX - low angle of take off and not as noisy as you might think - certainly no noisier than a loop or dipole at my QTH (which is happily quiet) Worth a look.
