I’ve had an HF rig for a while, but I didn’t have a transmitting antenna. So I finally put one up.
I don’t have a tuner at the moment, so whatever antenna I was going to put up needed to be resonant on the bands I wanted to use. I needed something easy to put up and take down since we are renting this house. And I wanted to cover at least down to 40m, including 30m. After a bit of research, I decided to install a Hustler 4BTV vertical with the add-on 30m kit.
This is a trap vertical. That means that it is electrically resonant on all of its bands; no tuner is needed. It covers 40 meters, 20 meters, 15 meters, and 10 meters out of the box; I added on the 30 meter trap kit, too, as I wanted to cover that band.
Assembly was simple and consisted of unpacking and checking the parts, putting things together in the right order, and placing a pipe into the ground as a mounting point. Since the mount needed to be removable, I dug a post hole, put a 6 foot 1.25″ galvanized pipe into it with about 24 inches protruding above ground level, and used a small amount of quick-dry concrete in the very bottom of the hole. This will allow me to dig out the mount relatively easily when needed.
The antenna covers the whole of 30m, 20m, and 15m with under a 2:1 SWR pretty easily; 40m and 10m are partially covered, but that’s to be expected. Tuning is achieved by adjusting the length of the sections between traps using simple hose clamps. You start at the bottom, tune the 10m section, then the 15m, 20m, 30m, and 40m sections in that order.
So far, the antenna has performed quite well, both receiving and transmitting. It’s simple to put up and take down. And it all seems quite well-built. I’m happy with it.
See you on HF!
