Mobile Transceiver: Kenwood TS-120S
I was using the TS-120S as a base station until I acquired the TS-830S. I have installed it in my Explorer along with 20m and 10m Hamstick antennas.
Base Transceiver: Kenwood TS-830S
My base 20m Antenna is a sloping 1/2 wavelength dipole fed with 100' of coaxial cable, (50 Ohm), through a 1:1 balun. Each arm is 16'-4", (4.88m), in length. One arm points towards the northwest and the other points towards the northeast. At the apex, (balun), they are 13 feet above grade. Both sections slope downwards to a height of 9' above grade. I generally work SSB CQ calls during the early evening hours and do some occasional contesting.
Antenna Analysis Using the EZNEC Application
The following plots were generated for my configuration at 85W power output using EZNEC, (Version 3.0.18). Click on images to see actual size plots.

Mobile Transceiver: Yaesu FT2200
I have this transceiver installed in my 4x4, (Explorer). Antenna is a Wilson 5/8 wavelength magnetic mount. I usually monitor the local 146.880MHz open repeater. This repeater is located on Mt. Potosi, (8500'), and coverage is from Los Angeles, CA to St George, UT and from Kingman, AZ to Beatty, CA. It also links to the Utah "Snowbird" system with coverage up the I-15 North to Wyoming, Idaho and Montana.
