28 MHz has been open most days this solar cycle, and so it’s been my band of choice from the car. The antenna sizes are much more reasonable, so it’s easier to get an antenna mounted on the car that works well.
I have a few options, but if static I have a 1/4 wave whip that’s around 9ft tall. They are sometimes referred to as a “Tank Whip” and can be purchased very cheaply online. The antenna requires virtually no tunning, you simply mount these on a 3/8 mag mount base and they work.
Antenna performance is subjective, but it also can be measured in PSK reporter.
Operating from the car allows you to pick an RF-quiet location and experiment.
