Typical industries that use these frequencies include: Farming and agriculture Road and bridge construction Volunteer Public Safety Paging Systems Long-haul trucking services. The primary users are properly licensed radio and television broadcasters as well as commercial communication services such as cell phones and two-way radios. Very high frequency is commonly used for FM radio broadcast, two-way land mobile radio systems, long-range data communication, and marine communications, just to name a few.
VHF waves must not exceed the local radio horizon of miles. VHF frequencies are less likely to be interrupted by atmospheric noise, issues with electrical equipment, and other interferences. There are different bands within VHF frequency, including low-band and high-band. Low-band VHF range of 49 MHz includes transmission of wireless microphones, cordless phones, radio controlled toys and more.
Despite the potential background noise this a popular option because of the low cost equipment. Transmission power is limited to under 50 mW, unless you are operating an assistive listening system in the MHz range. Also, a large antenna booster is necessary, measuring as much as 3 feet in length, thus limiting portability.
High-band VHF range is popular for professional applications. Also, be sure to purchase well-regarded brands, as cut-rate brands will often not perform as well. With nearly two decades of experience in radio equipment sales, service, and installation, Two Way Radio Gear understands its products and its customer base, and can help customers find the right solution for their two way radio needs.
One of the biggest questions newbies have about two-way radio communication is whether they should buy UHF or VHF radios. The length of your antenna determines the length of the radio waves.
The wavelengths of UHF ultra-high frequency are short so antennas for UHF two-way radios are typically small and stubby in size. VHF requires a slightly larger antenna to improve its range and how far it will travel. VHF antennas can receive channels 2 through 13 while UHF antennas can receive channels 14 through On a boat, there are a lot of places the noise can come from.
Listen to the receiver and note any changes in noise level. Another way to help with interruptions is bonding. This ensures that the notice goes away to the ground instead of radiated. All motors and such should be constructed in the ground. An issue that can occur with signals is frequency overlapping.
This means that if two radios are using the same frequency then the radio waves interrupt each other, and the transmissions overlap. This will most likely happen when they are in the range of each other or are in the same coverage area. This means that UHF frequencies have smaller waves that produce a greater range.
They are more likely to pass barriers like rocks and trees easier. VHF range is reduced due to signal degradation with barriers such as trees or hills. Together they both reach a good distance.
