VHF stands for “Very High Frequency.” VHF channels transmit at radio frequencies between 54 MHz and 216 MHz. Compared to ultrahigh frequencies, or UHF, VHF bands are relatively longer waves and are less prone to interference, thus they can carry the signal farther on a given amount of transmission power. These days, VHF signals are mainly used on marine vessels or vehicles in situations where signal obstructions will be at a minimum.
Many people use VHF antennas in their homes to receive a TV signal. With the rising cost of satellite TV, people are choosing to “cut the cable” and “ditch the dish” by switching to a VHF antenna to get a TV signal to their home. There is are a wide range of VHF antennas that are relatively simple to use that do not require professional installation. Determining whether you need an indoor or outdoor antenna depends largely on the strength of the signal in the area. Indoor antennas usually require a much stronger signal than outdoor. Once that has been determined, one can look up which free over-the-air channels are available in their area.
VHF antennas are also widely used by vehicle fleets when a two-way radio is needed while out in the field. To get the most gain, the antenna should ideally be mounted above the vehicle’s roofline. There are a large variety of VHF antennas available that can be installed in any type of truck, car, or van without the need to drill holes in the vehicle.
VHF antennas also offer a wide range of unique benefits for marine vessels. First, VHF signals have a significantly longer range compared to other HF bands. The main purpose of a VHF antenna is to transmit the signal the boat’s radio produces and to radiate the signal in the correct direction. VHF antennas for marine vessels need to be rugged enough to withstand the turbulent weather and rough conditions that are present while out on the water. This can either come in the form of a stainless steel “whip” antenna or a fiberglass encased antenna. Smaller vessels usually use a stainless steel whip antenna because they are extremely rugged.
