I found a great place to operate my radios that is out 20 miles or so from town, with little RFI, and on a levee well above the surrounding ground level. In the past I have set up portable vertical antenna's on tripods, etc... (There are no trees for EF wires on the levee.) So, now that it is getting colder, and because the coyotes and hogs tend to be curious about my runnin' buddy (Gunny the dog) once the sun goes down; I have decided to use the 2m antenna NMO mount on my trunk lid with an NMO to 3/4 x 24 adapter and an MFJ 17' SS collapsible vertical with coil base. I will attach counterpoises for the bands that I want to work by just threading some 24 awg wire under the nmo threads to make contact with the ground side threads and stretch them out. I'll be using my MFJ-9296 cw rig with an Elecraft T1 tuner. I'll be stationary while operating, but technically "mobile"...hehe AND, warm and cozy inside the car with Gunny asleep and safe in the back seat. I'm kind of excited to get out of the wind and weather. I'm sure I'll have some noise when the car is actually running, but I'll shut off the engine when it gets toasty inside. I have had good luck with 40m, 30m, 20m, and up when the antenna was on a camera tripod at around 6 feet high. I've worked all over the US and Eastern Europe with around 8 watts on 30m with that set-up. We'll see if my shenanigans work out on the trunk mount. Has anyone done anything similar?
