UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. ... The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz.

VHF radios are suited for long distances in and outdoor use. UHF radios operate at a higher frequency. This makes them ideal for wireless communications that need to penetrate through buildings, walls, or concrete. UHF radios are suited for indoor communication solutions, where obstacles are easily penetrable.

The J-Pole antenna is a common omni directional antenna used in amateur radio, particularly on the VHF and UHF bands.

So if your antenna is designed for UHF/HDTV frequencies only, then it will not receive the FM broadcasts very well. But if it is a combined UHF/VHF antenna, with low-band VHF reception, then you should be able to receive the FM broadcasts.

The standard TiVo remote control supports both radio frequency (RF) and infrared (IR) transmission. An RF remote control can “see” the RF sensor whether it is visible or not. However, IR transmission requires that the remote control be able to “see” the IR sensor on the front of the DVR.

Can a UHF radio communicate with a VHF radio? It is not possible to match UHF and VHF frequencies, because UHF radios only communicate in UHF 430-470 MHZ range and VHF radios communicate in VHF 150-174 MHZ range.

The ionosphere typically neither reflects nor absorbs waves with VHF or higher frequencies, but passes them through to space. There are no reflections back to the ground, so there is no useful propagation between stations on the ground.

Handheld UHF radio is a handy tool when four-wheel driving and the Aussie-made Oricom UHF5500 is one of the best on the market. ... For the past few years I've been using an Oricom UHF5500 model, which has proven extremely reliable and robust, and also provides clear and effective transmission and reception.

One way to make RF waves visible is with something like a radio telescope. An ordinary (light) telescope collects light and focuses it onto a receptor (CCD, photographic plate, the eye), thus making it possible to see the visible radiation emitted by a distant galaxy.

UHF frequencies are used for both analog and digital television broadcasts. UHF channels are typically given higher channel numbers, like the US arrangement with VHF channels 2 to 13, and UHF channels numbered 14 to 83.

1 Answer. CB or its close relatives fall into the HF frequency range (covering somewhere around 26 to 28 MHz, depending on country), so anything that accurately calls itself a VHF radio will not transmit (and most likely will not receive) CB. ... Therefore it cannot receive or transmit on CB frequencies.

Cell towers are usually grouped in areas with high population density or those places with the most potential users. ... The signals from a cell tower do not need a clear line of sight but a greater radio interference will eliminate reception.

UHF. UHF (ultra high frequency) signals operate at the higher end of the radio frequency spectrum. They can more easily penetrate metal and concrete structures, which makes UHF radios a good choice in built-up areas like towns and cities, or for densely wooded or hilly areas. It also makes them popular for indoor use.

HVT do not have the gps lines, there will be a sort of glowing light blue cluster marking where the target is on the map then you fast travel to the nearest safe house or mission and run to it. They do have GPS lines if you click on them.

The answer is yes, but it won't be over these high-frequency antennas. It will be basically where 4G is today, so you won't get the high-capacity [service].”

The primary mode of propagation for VHF radio waves is through direct waves. These travel in a straight line, becoming weaker as distance increases. Transmitting and receiving antennas must be able to 'see' each other for communications to be effective, so antenna height is critical in determining range.
