I had two HF6Vs. One was roof mounted with the roof mount radial kit. The other one was ground mounted. I now have the GAP Voyager. On 80 and 40, there is no comparison. The Voyager hears and transmits a lot better. I have helped install several Titans. The difference is not as dramatic but still, I tend to favor the Titan over the Butternut. 73 Bill / K8DXX
