As many of you who have been fallowing along on the “Adventure Machine” might already know, I’m adding Mobile HF capabilities to my comms set up. Right now I have an Icom IC-7100 running ham sticks for each band I want to use. These work ok for 10-20m, but the bandwidth becomes very narrow above 20m and changing bands is a real pita.
As some of you know my favorite part of the amateur radio hobby is building antenna systems. My requirements are:
1) the system has to be multi band 10-75m with the priority being 75m. On 75 meter I hang out between 3.940 and 3.988 and the most important frequencies are 3.946 and 3.955 since these are the emergency frequencies used by ARES in Oregon.
2) the Adventure Machine has a fiberglass top, and I’m not willing to line the underside with metal to make a ground plane.
3) I have an ATU that I can use to tune an antenna from 10:1 SWR down to 1.1:1 SWR that I can (and probably will) install.
So as I have been looking at mobile HF Antennas and have seen 2 that might fit the bill so far. A screwdriver antenna looks interesting, but I lack the skills to make it auto tune. The second one would be the Icom AH-4 tuner with a 108” SS whip.
What are you using for HF mobile?
