A dipole antenna is often an ideal solution for an antenna for receiving VHF FM broadcasts.

Switching from an indoor to an outdoor antenna can greatly improve FM reception. If you have a directional antenna, try switching to an omnidirectional antenna, or vice versa. Directional antennas can pick up stations from farther away, but omnidirectional antennas work well for closer stations.Nov 22, 2021

In a nutshell, the longer the antenna the more signals it can catch. So for your truck trying to catch the wavelengths of your radio station, typically what is referred to as a quarter-length antenna is best, so that's about 32 inches long.

This 300 Ohm FM antenna provide a better radio solution for radio stereo receiver on your table top, home, office, garage, basement and so on. Stretch the end of the antenna as far as possible away from the device for the best reception. Fits all receivers with a clip or terminal FM socket.

Wrap the radio antenna in aluminum foil to bring the signal in better and move the radio in different areas of the room. Some areas may pick up the radio signal better. Move closer to the window, or a place where fewer obstructions will interfere with the signal.

ANTENNA WIRE

you get the impression that the thicker the wire is, the better it will be for performance. A thick wire is always better than a thin wire.

The signal quality increases because your body is an antenna. You increase the radio antenna length and hence it's “gain” when you touch it. This effect doesn't happen at all frequencies and the increase in gain is fairly small. It can make a difference if the signal you are trying to listen to is weak.

In general, the length of the dipole antenna is kept fifty percent of the resonant frequency of the antenna. On a general note, an antenna of around 15 inches is enough to ensure the highest rate of reception.

I'd say the most significant difference between the two is convenience. You see, 75 OHM coax can be a lot easier to use when compared to the 300 OHM cable. Plus, most modern receivers come with 75 OHM cable connections. A standard dipole offers 75 OHM of balanced impedance, which is another thing to consider.
